The 1771-OA is an AC output module that is part of the 1771 product category. This module is an I/O module that is compatible for use with the PLC5 PLC. This module mainly features Eight (8) output channels that delivers voltage output range of 92-138VAC, 47-63 Hz. Each channel has an output current rating of 1.5 A however, the entire module does not exceed 6 Amperes. It has a surge current rating of 4 Amperes per output channel, capable of withstanding in 8.3 ms, repeatable every 1 second. This module has backplane current draw of 210 mA @ 5VDC.

The 1771-OA can be used to energize electrical devices such as Solenoid actuated devices, Indicating lights and sounding devices like horn, buzzer and siren. With the capability to deliver AC voltage and provide 1.5 A output current, this module may also be used to energize panel components that are typically AC voltage operated such as magnetic contactors and relays.
