Publication 1771-IN028D-EN-P - October 2008 6 DC (10...30V) Input Module Before You Begin The 1771-IBN series C DC input module is a sink input and requires a source output. A sink input provides a path to ground and a source output provides a positive voltage path. You must use this module in a 1771-A1B through 1771-A4B or later 1771 I/O chassis. Refer to the table for processor compatibility. Processor Capability System Type Use with Processors Cat. No. Local Mini-PLC-2/02 Mini-PLC-2/16 Mini-PLC-2/17 PLC-5/15, series B and later 1772-LZ, 1772-LZP 1772-LX, 1772-LXP 1772-LW, 1772-LWP 1785-LT Remote with a 1771-ASB remote I/O adapter PLC2/20 PLC-2/30 PLC-3 PLC-3/10 PLC-5/15, series B and later 1772-LP2 1772-LP3 1775-L1, 1775-L2, 1775-L3, 1775-L4 1775-LP4, LP8 1785-LT Do not place this module in the same I/O chassis as the 1771-IX thermocouple module. You can use this module in the same chassis as the 1771-IXE thermocouple module. This module has input filtering to limit the effect of voltage transients caused by contact bounce and/or electrical noise. Specifications for input filtering are listed in the specifications section of this document. Calculate Power Supply Requirements Your module receives its power for internal logic circuitry through the 1771 I/O chassis backplane from the chassis power supply. The module requires 280 mA from the output of this supply. To calculate the requirements for the backplane power supply, add 280 mA to the power requirements of all other modules in the I/O chassis. Calculating the requirements prevents an overload to the chassis backplane and/or backplane power supply. Publication 1771-IN028D-EN-P - October 2008 DC (10...30V) Input Module 7 Key the Backplane Connector Place your module in any slot in the chassis except the leftmost slot that is reserved for processors or adapters, noting that you: • should position the keying bands in the backplane connectors to correspond to key slots on the module so that you place the keying bands between 14…16 and 18…20. • can change the position of these bands if subsequent system design and rewiring makes insertion of a different type of module necessary. ATTENTION Observe the following precautions when inserting or removing keys: • Insert or remove keys with your fingers. • Make sure that key placement is correct. Incorrect keying or the use of a tool can result in damage to the backplane connector and possible system faults. Publication 1771-IN028D-EN-P - October 2008 8 DC (10...30V) Input Module Install the Module and Field Wiring Arm The 1771–IBN module is a modular component of the 1771 I/O system requiring a properly installed system chassis. Refer to Universal I/O Chassis Installation Instructions publication 1771-IN075 for detailed information on acceptable chassis and proper installation and grounding requirements. Limit the adjacent slot-power dissipation to 10 W maximum. WARNING ATTENTION If you insert or remove the module with power applied, or connect or disconnect the field wiring arm with field-side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Remove power from the 1771 I/O chassis backplane before you install the module. Failure to remove power from the backplane could cause: • module damage. • degradation of performance. • injury or equipment damage due to possible unexpected operation. IMPORTANT Apply firm and even pressure on the module to seat it into its backplane connector. To install the module and field wiring arm, follow this procedure. 1. Place the module in the card guides on the top and bottom of the chassis that guide the module into position, noting the following: • For a 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B I/O chassis, snap the chassis latch over the top of the module to secure it. Publication 1771-IN028D-EN-P - October 2008 DC (10...30V) Input Module 9 • For a 1771-A1B, 1771-A2B, 1771-A4B I/O chassis, swing the chassis locking bar down into place to secure the modules, making sure the locking pins engage. 2. Attach the 1771-WN wiring arm to the horizontal bar at the bottom of the I/O chassis noting the wiring arm pivots upward and connects with the module so you can install or remove the module without disconnecting the wires. Publication 1771-IN028D-EN-P - October 2008 10 DC (10...30V) Input Module Connecting Wiring to the Field Wiring Arm You make connections to the module through the 1771-WN field wiring arm. The arm pivots on the I/O chassis to connect with terminals on the front of the module and acts as a terminal strip. The wiring arm allows the module to be removed from the chassis without disconnecting wiring. WARNING WARNING ATTENTION The optional 1771-WHF and 1771-WHFB fused field-wiring arms are not certified for use in hazardous location applications. Use these optional accessories only in nonhazardous applications. If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury. • Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation. 1. Be sure all power is removed from the module before making wiring connections. 2. Swing the wiring arm up into position on the front of the module, noting that the locking tab on the module secures it into place. 3. Make your connections to the field wiring arm as shown in the connection diagram, using the label on the front of the wiring arm to identify your wiring. IMPORTANT The field-wiring arm terminal identification number is not the same as the number of the bit that controls that output. Publication 1771-IN028D-EN-P - October 2008 DC (10...30V) Input Module 11 I/O Module Groups Each module condenses two full-module groups (32 inputs) into each I/O chassis slot. For example: • module group 1 = inputs 00…17. • module group 2 = inputs 00…17 (module group 2 represents the second set of inputs). ATTENTION Observe proper polarity with DC power connections. Reverse polarity or application of AC voltage could damage the module. In the graphic on the following page, note the following: • Terminals 1…20 represent module group 1, with terminals 9, 10, 19, and 20 DC common. • Terminals 21…40 represent module group 2, with terminals 29, 30, 39, and 40 DC common. • Terminals on the left are even numbered 2…40 and terminals on the right are odd numbered 1…39. • If multiple power sources are used, do not exceed the specified isolation voltage. • The arrow in the figure shows that actual wiring runs in this direction.

Publication 1771-IN028D-EN-P - October 2008 DC (10...30V) Input Module 15 Status Indicators The module has 32 status indicators on the front plate. These represent the control status of the input. Each indicator is lit when voltage is present at the corresponding input. These indicators can flicker (momentarily light up) when the chassis in which the module resides is first powered up. This flicker is normal and in no way affects the control parameters of the system.
