Frequently Asked Questions

Can I mix AC and DC voltages on one module?

• Yes, the two output groups can handle different voltages.
• Each group of four outputs shares a common connection.

What controllers work with the 1746-OW8?

• It works with SLC 5/01 through SLC 5/05 processors.
• The module also fits in remote I/O chassis applications.

Do I need additional relays for different voltages?

• No, the built-in relays handle multiple voltage ranges.
• This eliminates the need for interposing relays.

What is the maximum current per output group?

• Each group of four outputs can handle 8.0 amps continuous.
• The total module current is 16.0 amps maximum.

How fast does the relay respond to signals?

• Both ON and OFF transitions take about 10 milliseconds.
• This response time works for most industrial controls.
