For example: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V). A value with the unit (V DC) at the end is a momentary value without any additional tolerances included. Indicates a nominal value. Indicates a typical value. A single dash alone in a table cell indicates that there is no information to be included in that cell. Use of two identical power supplies in parallel to provide continued operation following most failures in a single power supply. The two power supply outputs should be isolated from each other by using diodes or other switching arrangements. For example, two 10 A power supplies are needed to achieve a 10 A redundant system. Use of three or more identical power supplies in parallel, which are allowed to be connected in parallel for higher output currents, to provide continued operation following most failures in a single power supply. All power supply outputs should be isolated from each other by using diodes or other switching arrangements. For example, to achieve a 40 A redundant system, five 10 A power supplies are needed in an N+1 redundant system. Ensure that the power supplies are allowed to be connected in parallel to increase the output power.

The 1606-XLBRED20 redundancy module has two input channels, which can be connected to power supplies with up to 10 A output current. The module has one output, which can carry nominal currents up to 20 A. The module is suitable for power supplies with constant current overload behavior and any kind of “hiccup” overload behavior. The 1606-XLBRED20 is well suited for use in a redundant system in which the power supply itself is equipped with a DC-OK signal. Another application for this redundancy module is to separate sensitive loads from non-sensitive loads. This avoids the distortion of the power quality for the sensitive loads, which can cause controller failures.

The dual-input redundancy module can be considered as two single redundancy modules combined in one housing. The only common point is the circuit trace that ties the two separate circuits together at the output. The Mean Time Between Failure (MTBF) values in the following table are for the entire dual-input module. If you need the MTBF number of only one path, double the value from the table. Input / Output Current Conditions Lifetime expectancy(1) MTBF(2) SN 29500, IEC 61709 MTBF (2) MIL HDBK 217F N+1 Redundancy Input: 2 x 10 A Output: 20 A 1+1 Redundancy Input: 2 x 5 A Output: 10 A Notes at 24V and 40 °C (104 °F) Min 113,000 h 309,000 h Min 320,000 h 874,000 h at 24V and 25 °C (77 °F) — 7,837,000 h 20,310,000 h at 24V 40 °C (104 °F) — 19,408,000 h 46,382,000 h at 24V 25 °C (77 °F) — 1,774,000 h 1,817,000 h at 24V and 40 °C (104 °F) (Ground Fixed GF40) — 2,709,000 h 2,782,000 h at 24V and 25 °C (77 °F) (Ground Fixed GF25) — 3,675,000 h 3,707,000 h at 24V and 40 °C (104 °F) (Ground Benign GB40) — 5,620,000 h 5,674,000 h at 24V and 25 °C (77 °F) (Ground Benign GB25) (1) The Lifetime expectancy values that are shown in the table indicate the minimum operating hours (service life) and are determined by the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the manufacturer specification of the capacitor. The manufacturer of the electrolytic capacitors only states a maximum life of up to 15 years (131,400 h). Any number that exceeds this value is a calculated theoretical lifetime, which can be used to compare devices. (2) Mean Time Between Failure (MTBF) is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product. The MTBF value is a statistical representation of the likelihood of a device to fail. An MTBF value of, for example, 1,000,000 h means that statistically one unit fails every 100 hours if 10,000 units are installed in the field. However, it cannot be determined if the failed unit has been running for 50,000 h or only for 100 h.

Figure 10 - Front View Figure 11 - Side View Rockwell Automation Publication 1606-RM111A-EN-P - July 2020 13 Using Only One Input Instead of Both Channels You can use only one input instead of both up to a nominal input current of 20 A at 55 °C (131 °F) max ambient temperature. However, it is always recommended to connect both input path in parallel for reduced power losses and voltage drop.

When single-phase power supplies are used, connect them to different phases or mains circuits if possible. Use separate input fuses for each power supply. Set the power supply in “Parallel-Use” mode if this feature is available. It is desirable to set the output voltages of all power supplies to the same value. The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads. Rockwell Automation Publication 1606-RM111A-EN-P - July 2020 Use In a Tightly Sealed Enclosure When the redundancy module is installed in a tightly sealed enclosure, the temperature inside the enclosure is higher than outside. The inside temperature defines the ambient temperature for the redundancy module. The following table shows values from an installation in a tightly sealed enclosure. The power supply was placed in the middle of the box and no other heat producer was inside the box. Example: Redundancy for Controls Attributes Values and Descriptions Enclosure Rittal Typ IP66 Box PK 9516 100, plastic, 110 x 180 x 165 mm (4.33 x 7.09 x 6.50 in.) Load 24V, 16 A; (=80%) load is placed outside the box Input 2 x 24V DC, 8 A Temperature inside enclosure 42.4 °C (108.32 °F) (in the middle of the right side of the power supply with a distance of 2 cm [0.79 in.]) Temperature outside enclosure 23.1 °C (73.58 °F) Temperature rise 19.3 K (34.74 °F) In many cases, two power supplies are used, one for the demanding loads and another for the controls and sensitive loads, as shown in Figure 14. With the 1606-XLBRED20 redundancy module, the power supply for the demanding loads can be used as a redundant source to supply the controls, as shown in Figure 15. This provides a cost-effective solution to get redundant power for a PLC or controller system.

Use separate mains systems for each power supply whenever it is possible. The power supplies in Figure 16 can be either are 1606-XLX240EE or 1606-XLB240E.
