The Allen-Bradley 1771-OY is a PLC-5 series Contact Output Module. It handles 4 programmable contact outputs. These contacts can be configured via jumpers to be operated as normally open or normally closed. They are delivered from the factory as normally open. The current rating of outputs is 2 Amps. Power rating of the module is 200 VA. The power ratings for individual outputs are 30 VA at 138 Volts AC and 20 VA at 125 Volts DC per output. These outputs can tolerate voltages in the range of 0 to 250 Volts AC and 0 to 175 Volts DC applied to their terminals.

Plastic keying bands are used to configure every I/O chassis slot to accept an appropriate type of module. To connect Allen-Bradley 1771-OY module to the I/O chassis, the first thing you should do is to put plastic keying bands between pins 6 and 8 and between 16 and 18. Then you slide this module into the chassis and secure it with the locking bar. The 1771-OY is part of the modular PLC-5 concept and it can be taken out without rewiring. You only connect wires once to the 1771-WN field wiring arm. When you want to replace the module in the chassis, you just detach this field wiring arm for quick disconnection. When the 1771-OY operates, ambient temperatures should be kept at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). Note that the Allen-Bradley 1771-OY module contains mercury-wetted relays, and like all mercury-containing products it should be handled with care. Avoid extreme vibrations which can cause mercury to be released.
