Installation Guide

1. Set the terminal block rotary key to position B3 before mating with the I/O card.
2. Remove all field power (local bus and bussed field power) before inserting or removing the card.
3. Mount the card in an 8-wide I/O carrier in any of the 64 available slots.
4. Connect dry contact field devices to the terminal block, ensuring proper polarity.
5. Verify LED indicators (Power, Error, Active) confirm normal operation via DeltaV Explorer.

FAQ

• Q: What is a dry contact input?
  A: A dry contact input detects the open/closed state of a mechanical switch or relay contact without external voltage applied by the field device.
• Q: Can this module be used in a redundant configuration?
  A: Yes, S-Series cards support redundant I/O configurations for increased system availability.
• Q: What terminal block should I use?
  A: Use the matching S-Series terminal block with key position B3 (e.g., KJ4006X1-BF1 for 32-channel discrete).
• Q: Is the module hot-swappable?
  A: Only in non-hazardous areas with proper procedures; hazardous areas require power removal.

Selection Tips

• Use KJ3203X1-BK1 for high-density discrete input applications such as limit switches, pushbuttons, and relay status monitoring.
• Ensure field devices are true dry contacts; wet contacts may require isolated input modules (e.g., KJ3206X1-BA1).
• Plan power budget: 12 VDC local bus at 75 mA plus 24 VDC field power at 150 mA per card.
