FAQ

Q: What is the difference between IC694MDL655 and IC694MDL646?
A: The IC694MDL655 provides 32 points (4 groups of 8) with 2ms response time. The IC694MDL646 provides 16 points with 1ms response time and input filtering.

Q: Can this module be hot-swapped?
A: Yes, the IC694MDL655 supports RIUP (Removed and Inserted Under Power) for online maintenance.

Installation Guide

1. Insert the IC694MDL655 into any I/O slot of the RX3i universal backplane.
2. Connect 24 VDC field wiring to the input terminals (4 groups of 8).
3. Verify isolation between groups if required.
4. Configure input addressing via RX3i programming software.

Selection Tips

• For 16-point input, use IC694MDL646 or IC694MDL645.
• For 125 VDC input, use IC694MDL632.
• Verify total input current does not exceed backplane capacity.
