Common Applications
Product Precautions
WESTINGHOUSE 5X00357G04 combines contact wetting, event detection and time tagging in one enhanced SOE module. Field wiring resistance, shared-return design, power-check channel and event-buffer behavior must be validated during commissioning.
- Sixteen dry-contact inputs
- 42-55 V open-contact wetting
- 1/8 ms event-tag resolution
- Ground-fault and power-check functions
The installed signal path is Dry field contact → 5X00357G04 wetting and isolation → SOE debounce and time tag → Ovation event buffer. Record the as-left channel assignment and verify the affected path before release.
Important Notice: Isolate field contacts and follow ESD controls before handling WESTINGHOUSE 5X00357G04.

WESTINGHOUSE 5X00357G04 Technical Reference (PDF)WESTINGHOUSE 5X00357G04 Installation & Commissioning Guide (PDF)
The Technical Reference presents the applicable model data and interface details; the Installation & Commissioning Guide organizes field preparation, controlled replacement and acceptance checks for WESTINGHOUSE 5X00357G04.
Sequence-of-events recording
Time-tags sixteen field-contact transitions for event reconstruction.
Protection-system status
Captures ordered auxiliary-contact changes in monitored plant systems.
Wetting-supply supervision
Allows one configured channel to prove the on-board supply.
Ground-fault troubleshooting
Detects low-impedance paths between field conductors and earth.
Apply these controls to WESTINGHOUSE 5X00357G04 before isolation, removal, reconnection, energization and release.
1
Isolate field contacts and follow ESD controls before handling WESTINGHOUSE 5X00357G04.
2
Confirm the complete G04 identity and 1C31238H01 field insert.
3
Record all sixteen point assignments, common-return wiring and the configured power-check channel.
4
Do not connect any input or return conductor to earth ground.
5
Keep total closed-contact wiring resistance below the documented limit.
6
Correct ground faults before accepting event data from the affected module.
7
Test open and closed states and verify event timestamps against the synchronized I/O-bus clock.
8
Prove power-check, ground-fault, bad-quality and event-buffer behavior before release.
Technical notes
WESTINGHOUSE 5X00357G04 is a sixteen-channel Ovation enhanced sequence-of-events contact-input module with an isolated on-card 48 VDC wetting supply.
FAQ View All FAQ
-
How many contacts does WESTINGHOUSE 5X00357G04 monitor?It monitors sixteen single-ended dry-contact inputs.
-
What wetting voltage is used by WESTINGHOUSE 5X00357G04?The on-card supply provides 48 VDC nominal wetting, with 42 to 55 V documented at an open contact.
-
What current indicates a closed contact on WESTINGHOUSE 5X00357G04?The documented closed-contact current is 4 to 8 mA.
-
What event-tag resolution does WESTINGHOUSE 5X00357G04 provide?The module time-tags events at 1/8 ms resolution.
-
Which wiring resistance limit applies to WESTINGHOUSE 5X00357G04?Closed-contact recognition requires total wiring resistance below 100 ohms.
-
Which field insert is documented for WESTINGHOUSE 5X00357G04?The documented insert is 1C31238H01.
-
How is the WESTINGHOUSE 5X00357G04 wetting supply supervised?A selected input can be hard-wired and configured as the power-check channel; loss of that state marks the module points bad quality.
-
How should the final SOE acceptance test be run on WESTINGHOUSE 5X00357G04?Verify every contact state, timestamp accuracy, common return, power check, ground-fault indication and event-buffer handling.
