VIBRO-METER VM600 RLC16 – 16-Channel Relay Output Card | VM600 Rack-Based Machinery Protection Platform
Engineering Background
The VM600 platform by VIBRO-METER (a Meggitt company) is a globally recognized rack-based condition monitoring and machinery protection system deployed in critical rotating equipment applications — including gas turbines, steam turbines, compressors, and large pumps. The RLC16 is the dedicated relay output card within this ecosystem, providing 16 independent relay channels for alarm and trip signal routing to plant DCS, PLC, or safety relay systems.
Product Positioning
The RLC16 (P/N 200-570-000-211) serves as the final-stage output interface in a VM600 protection rack. It receives processed alarm/trip logic from upstream monitoring cards (such as the MPC4, AMC8, or IOC4T) and converts those states into hardwired relay contacts — ensuring deterministic, fail-safe signal delivery to plant control infrastructure. This card is essential for any VM600 installation requiring relay-based interlock or annunciation outputs.

Engineering Advantages
- 16-Channel Density: Maximizes relay output capacity per rack slot, reducing overall rack footprint and wiring complexity.
- Fail-Safe Architecture: Normally Energized relay configuration ensures trip output on power loss or card failure — critical for SIL-rated protection loops.
- Deterministic Output: Hardwired relay contacts eliminate network latency concerns inherent in soft I/O solutions.
- Seamless VM600 Integration: Plug-and-play compatibility with all VM600 rack generations; no additional configuration hardware required.
- Long Service Life: Industrial-grade electromechanical relays rated for high cycle counts in continuous-duty protection applications.
- Isolated Contacts: Each relay channel provides galvanic isolation from the backplane logic, protecting upstream monitoring cards from field-side transients.
System Architecture & Signal Flow
Within a VM600 protection rack, the RLC16 occupies a dedicated output slot and communicates with monitoring cards via the VM600 backplane bus. The typical signal flow is:
- Sensor Input → Transducer (accelerometer, proximity probe, velocity sensor)
- Signal Conditioning → VM600 input card (e.g., AMC8, MPC4)
- Alarm/Trip Logic Processing → VM600 rack backplane
- Relay Output → RLC16 relay contacts → DCS / PLC / Safety Relay / Annunciator panel
The RLC16 supports both alarm-level and trip-level relay assignments, configurable via the VM600 rack configuration software (RackConfig or equivalent toolchain).

Technical FAQ
Q: Is the RLC16 compatible with all VM600 rack generations?
A: Yes. The RLC16 is designed for the VM600 rack backplane and is compatible with all standard VM600 rack chassis variants.
Q: Can relay output logic (NE/NDE) be changed in the field?
A: Output logic is configured via the VM600 rack configuration software. Hardware jumpers may also be present depending on firmware revision — consult the VM600 RLC16 hardware manual (VIBRO-METER document reference) for your specific unit revision.
Q: What is the maximum switching voltage for the relay contacts?
A: The relay contacts are rated for 30 VDC / 1 A resistive load. Do not exceed contact ratings to avoid premature relay wear or contact welding.
Q: Do you provide the VM600 RackConfig software or licensing?
A: We supply hardware only. VM600 configuration software and licensing are managed through VIBRO-METER / Meggitt authorized channels. We can advise on software requirements upon request.
Q: Can this card be used as a spare/replacement for an existing VM600 installation?
A: Yes. The RLC16 200-570-000-211 is a direct drop-in replacement for any existing RLC16 card in a VM600 rack. No rack modification is required.
