FAQ

Q: What is the maximum load per channel?
A: Each channel supports up to 60 VDC at 1 A.

Q: Can I remove this module while the system is running?
A: Field power must be removed before module removal. The unit cannot be inserted or removed with system power energized on the field circuit.

Q: What terminal block do I need?
A: Use a rotary-keyed terminal block set to position B5 for proper compatibility.

Installation Guidelines

1. De-energize field power before connecting or disconnecting the module.
2. Set the terminal block key to B5.
3. Align the module with the carrier and press firmly until seated.
4. Re-apply field power only after verifying all wiring connections.

Selection Tips

• Select KJ3208X1-BA2 when you need isolated discrete outputs for solenoids, relays, or indicator lamps.
• Ensure your carrier supports Series 2 I/O modules.
• Verify load current per channel does not exceed 1 A.
