Leakage currents are present on solid-state outputs; these currents are capable of energizing highly sensitive output load devices such as low-power latching relays. Open contacts on output relays assure that no leakage currents occur in critical applications. ") ) %$ *') %$ #% %' %*)&*)( Allen-Bradley relay contact output modules offer either normally-open (Form A) or normally-closed (Form B) configurations. You can select the form configuration for four of the contact output modules, the 1771-OW, -OW16, -OWN, and -OX. The 1771-OW has eight selectable outputs. The 1771-OW16 has eight normally-open and eight selectable outputs. The 1771-OWN has 32 selectable outputs.The 1771-OX has four selectable outputs. Selectable–configuration means you can predetermine whether an output will be on or off when local power is lost to the control system or the output module. The 1771-OWNA has 32 non-selectable normally-open contacts. 1771 Digital I/O Relay Contact Output Modules 2 Isolation helps assure that a failure on one output circuit does not pull down another output circuit, thus increasing overall system integrity. This isolation also protects the backplane logic from line transients on the output circuits. !" You can apply either ac or dc voltages to relay contact output circuits. The range of these voltages can be broad (within the module’s operating specifications) without impacting the module’s performance. Contacts on relays permit dc outputs to be sinking or sourcing as required by the devices being controlled. Solid-state outputs require specific compatibility with the load device as to current sinking or sourcing. " You can use analog module inputs for different devices by switching circuits through relays. Analog signals are typically low voltage (+10V dc) and low current (4-20 mA). Contact resistance can be critical, and should be accounted for in low-impedance circuits. This publication provides you with information about Allen-Bradley’s relay contact output modules. The publication is divided into two sections. The first section contains general information that pertains to all of the relay modules; the second section contains module-specific information. The following table lists the relay contact modules and the page number on which you can find information about each.

Electromechanical relays contain the most economical design for power applications. These modules typically can handle line surges and noise through closed contacts. Electromechanical relays are not recommended for low voltage/low current applications. Electromechanical relays are generally slower than dry-reed relays. They are not recommended for use in environments with contaminants such as acid, ammonia, nitrogen, or chlorine (noxious environments) because they are not hermetically sealed. Allen-Bradley modules that use electromechanical relays include the 1771-OW, 1771-OW16, 1771-OWN, and 1771-OWNA modules. Dry-reed relays are noted for their speed. These relays are well-suited for low-voltage, low-power applications. They are hermetically sealed and thus offer protection in noxious environments. Dry reeds, however, cannot handle surge currents due to their low-voltage design. Allen-Bradley modules that use dry-reed relays are the 1771-OYL and 1771-OZL modules. The mercury-wetted relay is a power version of the dry-reed switch. These relays feature long life and high contact reliability because the mercury re-coats the contacts on every operation. Mercury-wetted relays are also hermetically sealed and have no bounce on outputs and offer a clean switch. Of the three types of relays, mercury-wetted relays are the slowest (10 ms). ATTENTION: The 1771-OX module contains mercury-wetted relays. At the end of the equipment's life, it should be collected separately from any unsorted municipal waste. ,$#+#'& .

" ! Publication 1771Ć2.181 - September 1997 Relay contact output modules receive power through the 1771 I/O chassis backplane from the chassis power supply. Refer to the module specifications on pages 11 through 24 for the current required from the power supply (in mA) to operate the module. You should total the current requirements for all the modules in the chassis to avoid overloading the power supply or the I/O chassis backplane. Plastic keying bands shipped with each I/O chassis let you configure your I/O slots to accept only one type of module. You can configure any backplane connector in an I/O chassis to receive your contact output module except for the leftmost connector, which is reserved for adapter or processor modules. Since mixed voltages are often used on relay modules, most of the contact output relay modules all have the same keying slots. Refer to the module specifications for specific keying positions. Status indicators on the front of each module show the system logic side status of the output relays. Each module has one indicator per output. When the indicator is on, it means the output relay coil is energized; when the indicator is off, it means the output relay coil is not energized. You can quickly isolate many types of external hardware-related faults by comparing these indicators with their corresponding output devices, and the control program. 1771 Digital I/O Relay Contact Output Modules 5 When using relay contact output modules, you must consider the following: Relays have a finite number of operations during their life. This varies depending on the current loads and voltages you apply relative to the relay’s design specifications. A relay that is always operating at the same load conditions has a very predicatable life. A low power load delivers longer contact life when the minimum load conditions are met. Varying load conditions can drastically shorten contact life. Do not operate a contact at low current or voltage conditions after operating the same relay under high power conditions. Operate at low power first, then at high power. Electromechanical relays typically have a longer life than dry-reed relays. When selecting a relay type, we recommend that you consider the number of operations expected over time and the load placed on the relay. The switching frequency of a relay is limited by its mechanical characteristics. To obtain maximum relay life, do not exceed the maximum switching frequency of the module. All types of relay outputs have a specified time in which contact is made or broken (pull-in or drop-out times). Dry-reed relays are notably faster than electromechanical. Electromechanical and dry-reed relays have contact bounce. Mercury-wetted relays do not have bounce. All wiring between the module and the load creates a certain amount of capacitive loading for the relay contacts. This capacitance is discharged during contact closure. The resulting peak current flow causes additional wear of the contact. Avoid this effect by keeping your cable lengths as short as possible, and, if possible, insert a resistor in series with your load. Locate the resistor as near as possible to the field wiring arm. Size the resistor properly. Publication 1771Ć2.181 - September 1997 6 1771 Digital I/O Relay Contact Output Modules Many loads (relays, coils, motor starters, solenoids, motors, etc.) contain a certain amount of inductance. This inductance does not allow an instantaneous change of current when the relay contacts open. As a result, the voltage across the contacts rises to a very high level, and causes arcing between the contacts. This arcing reduces the life of the contacts.We recommend you use a resistor-capacitor (RC) network (also called a “snubber”) across the contacts in all circuits. ATTENTION: Failure to use a resistor-capacitor (RC) network across the relay contacts can result in generation of electromagnetic noise which could disrupt nearby electrical equipment, including the 1771 I/O chassis. ! The best location for the RC network is across the relay contact terminals on the field wiring arm. This location suppresses the noise where it is generated, and does not let the noise radiate along the wiring going to the load. The 1771-OW, -OW16, -OWN, -OWNA, -OYL, and -OZL modules are not approved by UL/CSA for use with reactive loads. The 1771-OX module is designed with selectable dc surge protection circuitry. The formula necessary to determine the appropriate values for the RC network is shown below. Use a capacitor with an ac voltage rating greater than the maximum voltage seen across the contacts. Use a 5%, 1 Watt carbon composition resistor. Resistor-Capacitor Network Calculation of Values I R C = I2/10 in µF R = V/(10Ia) in ohms V C Publication 1771Ć2.181 - September 1997 Where: I = Amps V = Volts a = 1 + (50/V) 1771 Digital I/O Relay Contact Output Modules 7 Incandescent lamps also create a spike due to their low turn-on resistance before they become hot. Therefore, you must use derating or surge suppression (for example Allen-Bradley surge suppressors 1492-H2K120, 1492-H2K024, and 1492-H2K240). Specified relay current is typically derated at ten times the steady-state current of the incandescent lamp load. For derating, you can calculate cold-start load by measuring the cold load resistance. You can also experience large current surges when bulbs burn out (e.g. 20-50 amps). The operating temperature of the relay greatly influences the life of the relay contacts. The 1771 relay contact output modules have a maximum operating temperature of 60o. Operation at lower temperatures will extend relay contact life. Since electromechanical relays are not hermetically sealed, they are not recommended in environments with contaminants such as acid, ammonia, nitrogen, and chlorine— especially with voltages under 24V ac/dc or for prolonged periods without operation. Such environments contaminate the relay contacts, causing reliability problems. Higher voltage usage, between 24 and 120V ac/dc, and continued operation help keep contacts clean as a result of the burning off of contact contaminants. Relays are also subject to reliability problems under high vibration environments as mechanical motion can intermittently break contacts. Mercury-wetted relays and dry-reed relays are hermetically sealed from the environments, thus preventing environmental reliability problems. Mercury-wetted relays are generally sensitive to mounting position. The life of the relays in the output modules is directly affected by the load through the contacts and the operating temperature. Minimum currents and voltages specified for 1771 relay contact output modules are selected to provide clean contacts throughout the life of the contacts. The relays can operate below the minimum specifications, but operation will not be reliable. Exceeding the maximum power ratings for the module will shorten the life of the relay contacts. Do not operate relay contact output modules at power levels greater than maximum specifications. By using the operating range graphs, you can determine if you are within the operating capability of the relay. You only need to know any two of the following: • voltage • load current (mA) • load power consumption (W) Publication 1771Ć2.181 - September 1997 " "+$ $0 '&++ ,+(,+ ',$* 8 Using Figure 1, follow this example: Given a 30V dc, 4W indicator, is this in operating range? 1.

If this is within the shaded area of the graph, you are in the permissible operating area for the relay contact output module. (In this example, you are in the permissible operating range.)

You can use the 1771ĆOWN module to drive an input of the following ac modules: 1771ĆIA, ĆIA2, ĆIAD, ĆIAN, ĆID, ĆID16, ĆIN, ĆIND. The 1771ĆOWN module can drive an input of the following dc modules at nominal voltage: 1771ĆIB, ĆIBD, ĆIBN, ĆIH, ĆIQ, ĆIQ16, ĆIT, ĆIV, and ĆIVN. For reliable operation, a load current of at least 10mA should be maintained. . Do not attempt to increase load current or wattage capability beyond the rating by connecting two or more outputs in parallel. The slightest variation in output relay switching time may cause one set of the contacts to switch the total load current. When the output image table bit at the address corresponding to any output is energized (set to 1), the corresponding relay contact is closed or opened, respective to the jumper setting. All outputs are individually selectable for either normallyĆopen or normallyĆclosed operation. They are preset for normallyĆopen operation at the factory. See next page for relay output jumper settings.
