Product Introduction

Many turbine and compressor protection layouts require more alarm and trip outputs than the four built-in relays on standard IOC4T cards. The VM600 RLC16 solves this limitation as a rear-mounted relay expansion card inside VM600 racks. It communicates over the rack backplane and works alongside MPC4 protection modules to execute safety interlock logic.

Unlike signal acquisition cards such as CMC16, RLC16 handles only relay switching without sensor input processing. Each relay supports configurable normally energized or de-energized mode via on-board jumpers. It supports hot swap under controlled conditions, reducing rack shutdown time during spare replacement. Stable operation within -25 °C ~ +65 °C fits power plant and offshore petrochemical environments.

Quality Control Process

Inbound Traceability & Visual Inspection

Check serial number marking, hardware revision label and PCB integrity. Inspect for circuit corrosion, solder repair traces, damaged connectors or component discoloration. Confirm printed part number matches customer required variant.
Live Bench Functional Test

Mount RLC16 inside standard VM600 ABE04 test rack paired with MPC4 controller. Complete power-on initialization, backplane communication test, full 16-channel relay switching test and continuous 24-hour aging run. All relay action logs are saved as test records.
Electrical Performance Testing

Continuity check for every relay contact, insulation resistance testing. Verify no abnormal leakage current under standard test voltage. Confirm front/rear indicator LED status.
Hardware Revision & Compatibility Recording

Document hardware revision and onboard circuit version. We will verify compatibility with your existing VM600 system firmware before shipment if requested.
Final QC & Anti-Static Packaging

QC engineer signs off all passed test items. The module is sealed inside anti-static bag, wrapped with shock-resistant bubble film and packed in rigid carton. A QC Passed label with test date is attached. Test photos or video can be provided on request.

Field Replacement Pitfall Guide

❗ Hardware Variant Compatibility Risk

200-570-000-111 and 200-570-101-015 represent different hardware revisions of RLC16. They cannot be freely interchanged in all VM600 rack firmware environments. Mismatched variants lead to relay failure to trigger or unrecognised module alarms.

Tip: Record full part number of original card before ordering.

Case Reference: One gas compression station replaced RLC16 with incorrect part variant; protection trip relays failed to activate during commissioning, consuming three days of troubleshooting.

❗ NE / NDE Jumper Configuration Mistake

Relay energised mode is set by physical jumpers on the RLC16 board, not software. Incorrect jumper positions reverse alarm and trip logic. Always take clear photos of jumper layout on the old module before removal. Do not rely on memory.

❗ Front and Rear Rack Slot Matching

RLC16 installs on the rear cage of VM600 rack. It must correspond to the matched front processing module slot. Mismatched slot allocation causes communication loss. Check rack slot wiring diagram before installation.

❗ Hot Swap Operation Rules

Hot swap is supported, but avoid executing hot swap during active machine protection mode. Unexpected relay state changes may trigger unplanned equipment trips. Best practice: perform card replacement during unit shutdown.

❗ Strict ESD Protection Requirements

Relay drive circuits are sensitive to electrostatic discharge. Wear anti-static wristband and operate on anti-static mat. Dry winter environments raise static damage risks. Bare-hand contact often leads to hidden circuit failure.

Quick Conclusion

VM600 RLC16 is exclusive rear expansion relay card for VIBRO-METER VM600 ABE04x rack systems; it cannot operate independently or work with third-party PLC platforms.
Core purpose: expand alarm and trip relay outputs when IOC4T native relay channels are insufficient. It does not process vibration sensor signals.
Confirm complete part number, hardware revision and system firmware compatibility before purchase.
OEM manufacturing has stopped, stock volume is limited; lead time depends on available inventory.
Every spare module is fully bench tested prior to delivery, test documentation available upon request.

FAQ

Q1: What is the difference between 200-570-000-111 and 200-570-101-015?

A1: They are different hardware revisions of RLC16. Internal circuit layout and compatible VM600 firmware sets differ. Confirm compatibility with your on-site MPC4 and rack controller before replacement.

Q2: Can RLC16 collect vibration signals from proximity probes?

A2: No. RLC16 is purely a relay output expansion card. Signal acquisition requires MPC4 or CMC16 modules.

Q3: Can I set relay logic via VibroSight software?

A3: No. NE/NDE relay mode is adjusted by physical jumpers on the PCB. Software only controls relay trigger timing, not energising logic.

Q4: What warranty terms apply?

A4: 12-month warranty after delivery, covering functional defects under standard operating conditions. Damage caused by wrong wiring, static discharge or improper hot swap is excluded.
