The Allen-Bradley 1771-OW is a selectable contact output module from the 1771 product bulletin. It has Eight (8) relay contact output channels in Four (4) groups of Two (2) channels each. Output channels are selectable for Normally Open (N.O.) or Normally Closed (N.C.) orientation with N.O. as the default configuration. Output relays can be operated at 24 – 138VAC RMS and 24 – 125VDC. This module uses the 1717-WD Field Wiring Arm and installed to any 1771 I/O chassis.

The Allen-Bradley 1771-OW is a selectable relay output module. This module features Eight (8) relay output channels in Four (4) groups of Two (2) channels each with each group installed with individual common. Each output channel can be assigned as a Normally Open (N.O.) contact or Normally Closed (N.C.) contact with N.O. as the default configuration. This module is ideally used with resistive loads as it does not come with surge limiting circuitry.

The 1771-OW Allen-Bradley OUTPUT MODULE may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
