PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-OD16 is a PLC-5 digital output module providing isolated AC load control. It installs into compatible 1771 I/O chassis including the 1771-A1B and 1771-A4B or later. The unit delivers sixteen isolated AC output channels operating between 74 and 138 Volts AC. It operates across a line frequency range of 47 to 63 Hertz.
The front faceplate features one green active indicator, one red blown fuse indicator, and sixteen red status LEDs. The module supports up to 2 Amperes per output channel with a maximum total module rating of 8 Amperes. Backplane current draw is rated at 200 mA. Power dissipation ranges from 1 to 13 Watts during regular industrial operation. Thermal dissipation spans from 3.4 to 44.4 BTU per hour.
