FAQ
- Do the outputs have built-in fuses?
No, you need a fused terminal base like the 1794-TBNF for protection. - What is the minimum load this 1794-OA16 module can control?
It needs at least 5mA of current per output to work correctly. - Can I use this module to control a 240V AC load?
No, its maximum voltage is 132V AC. Use a different module for 240V. - How do I wire the common connection for the outputs?
You must connect an external 120V AC common source to the terminal base. - Is there delay when turning outputs on or off?
Yes, there is a small delay of up to one-half cycle of the AC power.
