FAQ for CP1W-40EDT1
What's the difference between 40EDR and 40EDT1?
40EDR: relay output (5A, AC/DC). 40EDT1: PNP transistor output (0.3A, DC only). Choose 40EDR for AC/high current, 40EDT1 for DC/high-speed.
What's the maximum total current?
0.3A per point, 1.2A per common (8 points), 4.8A total unit maximum. Plan load distribution to stay within ratings.
Can I use this for solenoid valve control?
Yes, common application. 0.3A per point suits most 24VDC solenoid valves (typically 0.1-0.2A each). Add flyback diode for inductive load protection.
How do I wire PNP output?
Load + to 24V+, load - to output terminal. Output switches 24V+ to load when ON. Common terminal connects to 24V+.
