Frequently Asked Questions
What loads can this output unit switch?
0.5A per point: solenoid valves, indicator lamps, small relays, pilot lights. For higher current loads, use output to control external relay/contactor.
What's the maximum total current?
4A per unit maximum. With 32 outputs, if all ON, each limited to 0.125A average. Plan load distribution to stay within unit rating.
What happens during short circuit?
Internal protection shuts off output. Fault indicated in controller. Output resets when short removed and controller cycles. Repeated shorts may damage unit.
Can I use this output for PWM control?
Yes, transistor output supports PWM. Max frequency: approximately 5kHz. For high-frequency PWM, use dedicated high-speed output unit.
