Digital timer for solenoid
Hello smart people,
Can you help me figure out how to hook up a 120V solenoid to a digital timer? It's for an air cannon. The air cannon needs to go off once every 24 hours to clean out a filter.
I assume the timer is an output?
I think I need fuses for this?
Thanks in advance for your help!

You can use a variety of timers. Which one will determine how it's wired. Pick up a recycle timer with the delay voltage and current ratings you want then read the instructions. They will have a simple diagram to follow. Fusing most likely will be needed.
It's not a physical timer, it's a PLC timer.
Yes, the timer will control an output, IDK how large your cannon solenoid is, so to protect the output contacts of the PLC, consider using an interposing relay. Cheaper to change out the relay than a PLC card. Fusing will depend on how you connect and what your PLC instructions indicate..
I wish the PLC did have wiring instructions ! I've been handed a solenoid, directed to a PLC rack, and told, "Make it work."
Is your plc an AutomationDirect PLC?
**Edited**
If yes, what part numbers are you using? If no, it maybe best if you go to www.plctalk.net and ask your question. There is a large customer base on that forum for other model plc's.
Are you familiar at all with PLCs?
That's a nasty test of abilities.
Not at all. Ugh.
Can you post photos of the PLC you're using and the valve? On the valve, there should be information printed on it showing coil voltage and wattage. Like this:
Are you an electrician?
Solenoid valve timers are used to control your solenoid valves according to the desired schedule. Connecting a timer helps automate the solenoid valve's opening and closing intervals. The time periods during which the valve remains on and off can be programmed within the timer yielding an effortless operation.
