FAQs
Q1: How many relay channels are provided?
A1: The module includes 8 relay channels—4 Form A and 4 Form C.
Q2: What is the maximum voltage and current supported per channel?
A2: 240 VAC or 30 VDC at 4 A for resistive loads.
Q3: Can this module be inserted or removed while powered?
A3: Yes, it supports hot-swap capability under controller power.
Q4: What is the typical mechanical life sur the relays?
A4: 50 million cycles under standard conditions.
Q5: Is the module suitable for lamp loads?
A5: Yes, it supports up to 0.5 A at 240 VAC or 30 VDC for lamp loads.
Q6: Does it provide channel-specific fault indication?
A6: Yes, each channel has a green LED indicator; module status is shown with red and amber LEDs.
Q7: Is there galvanic isolation between channels?
A7: Yes, each relay output is galvanically isolated from the others and from the logic.
