FAQ

Q: How many inputs can read analog signals?

A: Six of the 16 inputs can work as analog.

Q: What load can each relay output switch?

A: Each output handles up to 5 A.

Q: Does it need a separate clock module?

A: No, the real-time clock is built in.

Q: How do I add communication ports?

A: Use Zelio Logic extension modules.

Q: Experienced tip: what should I check before buying?

A: Count your inputs and outputs first. Check the supply voltage. Confirm relay or transistor outputs. Then match the program size to your logic.

Q: Buying guide: how do I choose between this and a PLC?

A: Pick this relay for small logic and timing jobs. Pick a PLC for fast motion or large programs. This unit saves cost and space. It also ships in 12-24 hours with a 12-month warranty.
