Common Applications
Product Precautions
In a WDPF Q-Line contact path, WESTINGHOUSE 7379A06G02 3A99160G02 converts field-contact states into two eight-bit DIOB bytes. Cable resistance, leakage, filter timing and address jumpers are key acceptance points.
- Sixteen filtered contact inputs
- 48 V nominal contact wetting
- Optical isolation per input
- Selectable data-bit polarity
Prove the QCI path with controlled contact changes on both eight-bit groups while checking wetting voltage, leakage, filter response, polarity and DIOB addressing.
Important Notice: De-energize or isolate connected contact circuits before handling WESTINGHOUSE 7379A06G02 3A99160G02.

WESTINGHOUSE 7379A06G02 3A99160G02 Official Technical Reference Excerpt (PDF)WESTINGHOUSE 7379A06G02 3A99160G02 Installation & Commissioning Guide (PDF)
The official excerpt identifies the combined QCI assembly and filtering behavior; the installation guide covers two-byte addressing, wetting circuits, leakage and contact-state proving.
Machine-status input
Collects sixteen dry-contact indications.
Protection-contact monitoring
Filters short disturbances before DIOB transfer.
Legacy Q-Line replacement
Restores the exact combined QCI card identity.
Digital input troubleshooting
Separates contact, cable, wetting supply, filter and DIOB checks.
Isolate the 48 V wetting supply and map both eight-bit contact groups before disturbing the combined QCI assembly.
1
De-energize or isolate connected contact circuits before handling WESTINGHOUSE 7379A06G02 3A99160G02.
2
Preserve both identifiers in the combined model record and verify the G02 group.
3
Record all channel assignments, polarity inversion settings and address jumpers.
4
Keep open-contact leakage resistance at or above 50 kilohms.
5
Apply the 60-ohm closed-circuit wiring equation to every field path.
6
Do not expect pulses shorter than 2.6 ms to pass the digital filter.
7
Verify the 48 V nominal wetting supply and each channel LED.
8
Release the card only after all used contacts, polarity settings and DIOB bytes pass.
Technical notes
WESTINGHOUSE 7379A06G02 3A99160G02 is a sixteen-channel Q-Line QCI digital contact-input card with an isolated 48 V wetting supply.
