Installation Guide

1. Chassis Insertion: Slide module into designated slot until flush with chassis front
2. Flat Cable Connection: Connect horizontal IO bus flat cable to module front connector
3. Field Termination: Use compatible FTA (e.g., FC-TSDI-1624) for field wiring interface

5. Hot-Swap: Module can be replaced with power on; verify process impact before removal

FAQ

Q: Does this module require an FTA?
A: Yes. The FS-16DI-RL is the I/O module installed in the chassis. Field wiring connects via a compatible Field Termination Assembly (FTA) such as FC-TSDI-1624.

Q: Can inputs from different voltage sources be mixed?
A: All 16 channels share common configuration. Verify field device voltage compatibility before installation.

Q: What is the replacement procedure?
A: Disconnect flat cable, loosen screws, slide out old module, insert new module, reconnect flat cable. Address is automatic based on slot position.

Selection Tips

• Verify voltage compatibility with field devices (10–30 VDC range)
• Pair with appropriate FTA based on wiring requirements (screw terminals, wire gauge)
• For SIL-rated applications, ensure complete safety loop calculation includes this module
