Product Introduction

TRICONEX 3625C1 is a 16-channel TMR digital output module for Tricon SIS/ESD systems. It provides fail-safe 24VDC control for critical safety devices in high-hazard processes.

Its 2oo3 voting eliminates single points of failure. The module’s 2A per-channel rating and 1500VDC isolation deliver robust, deterministic control for valves and relays.

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify OEM part number, serial number, hologram; inspect PCB for burns, bent pins, cold solder joints.
2. Live Testing: Seat in Tricon HD backplane; apply 24VDC; confirm PASS LED; 24-hour cycle test on all 16 channels.
3. Electrical Testing: Verify 1500VDC isolation; check on-state drop <1V; leakage <2mA per channel.
4. Firmware/Config Backup: Record firmware rev (e.g., v3.5.2); save channel mapping and voting config.
5. Final QC & Packaging: Anti-static bag; QC tag with test date; shock-absorbent case with test report.

Installation Pitfalls & Guide (Engineer to Engineer)

• ❗ Backplane Incompatibility: 3625C1 only fits Tricon HD backplanes. Will not work in Trident or standard Tricon racks.
• ❗ Overcurrent Damage: Exceeding 2A/channel triggers shutdown and FAULT LED. Calculate load resistance before hookup.
• ❗ Wiring Polarity: Reversing 24VDC damages output transistors. Label wires before disconnecting.
• ❗ Firmware Rev Mismatch: Mixing revisions causes voting errors. Match replacement module rev to system.
• ❗ ESD Risk: Ungrounded handling fries TMR logic. Use ESD strap and mat; $4k+ modules at risk.

Replacement Guide:

1. Pre-install: Safe system state; power down; ESD protection.
2. Removal: Extract module; label wiring; photo DIP switches.
3. Install: Seat firmly; set switches; reconnect 24VDC with correct polarity.
4. Power-on Test: Verify PASS LED; channel test; confirm TMR voting health.

FAQ (Frequently Asked Questions)

Q: Is 3625C1 hot-swappable?A: Yes, in Tricon v8–v10 HD chassis. TMR voting prevents downtime; confirm system firmware supports hot-swap.

Q: What’s the warranty?A: New original: 12-month OEM warranty. Refurbished: 6-month functional warranty; excludes labor.

Q: Can it drive 120VAC loads?A: No. 24VDC only. Use interposing relays for AC loads.

Q: Difference between 3625C1 and 8312?A: 3625C1 = 16-ch 2A 24VDC (HD backplane). 8312 = 16-ch 100mA 24/48VDC (standard backplane).

Q: What causes FAULT LED?A: Channel overload, short circuit, voting mismatch, or firmware rev mismatch. Use Tricon diagnostics to isolate.

Q: Is 3625C1 obsolete?A: Not yet. Supported in current Tricon systems. Check Schneider for EOL notifications.

Q: What’s the self-test frequency?A: Every 500ms; detects open/short circuits and voting discrepancies.
