A-B 1771-OX

1771-OX is a special mercury wet spring relay output module for the 1771 platform. The four channels are completely isolated from each other, and the normally open and normally closed contacts can be switched through jumper wires on the board. It can directly drive contactors, solenoid valves, and on-site valve coils, and can adapt to AC and DC loads.

Allen-Bradley relay contact output modules offer either normally-open (Form A) or normally-closed (Form B) configurations. You can select the form configuration for four of the contact output modules, the 1771-OW, -OW16, -OWN, and -OX. The 1771-OW has eight selectable

outputs. The 1771-OW16 has eight normally-open and eight selectable outputs. The 1771-OWN has 32 selectable outputs.The 1771-OX has four selectable outputs. Selectable–configuration means you can predetermine whether an output will be on or off when local power is lost to the control system or the output module. The 1771-OWNA has 32 non-selectable normally-open contacts.
