Allen-Bradley 1771-OAD

This module uses zero-crossing technology to allow turn-on when the output voltage is less than a specified voltage (typically 40 to 50V). This module receives its power through the 1771 I/O chassis backplane from the chassis power supply. The module requires 295mA from the output of this supply.

Outputs per module: 18
Module location: 1771-A1B through-A4B or later I/O chasis, 1771-AM1, -AM2 chasis
Output voltage range: 10 to 138V ac 47 - 63Hz
Output current rating: 2A per output - not to exceed 8A per module
Surge Current (max): 25A per output for 100ms, repeatable every 1 sec
