Product Questions
-
Q: What types of loads can the 1771-OW control?
A: It is suitable for controlling resistive AC/DC loads such as solenoids, pilot lights, and contactors. Inductive loads are not recommended due to lack of surge suppression circuitry. -
Q: How are the relay contacts configured?
A: Each output can be individually strapped for N.O. or N.C. operation using internal jumpers. -
Q: Is the module compatible with all 1771 chassis?
A: Yes, except for the extreme left slot which is reserved for Remote I/O Adapter modules. -
Q: Is the 1771-OW hot-swappable?
A: No. Power must be turned off before inserting or removing the module.
