The identification of 200-570-000-014 as RLC16 is supported by VM600 spare-parts references and product documentation. The 200-570-101-013 number is specifically identified as RLC16Mk2, with VM600Mk2 compatibility.
One caution: some secondary listings mix specifications between the original RLC16 and RLC16Mk2. I would not carry over contact ratings, temperature limits, or electrical interface details from one generation to the other without checking the applicable datasheet.
Application Scenarios & Pain Points
A relay card becomes safety-relevant when its contacts are part of a turbine trip, compressor shutdown, or overspeed-related control chain. A relay that merely changes state during a bench test is not necessarily a proven protection output.
- Steam and gas turbine protection: RLC16 provides extra relay outputs for alarm and trip conditions generated by the VM600 machinery-protection system.
- Compressor monitoring: Additional relay channels can be assigned to high vibration, bearing condition, or other configured protection events.
- Balance-of-plant machinery: Pumps, motors, fans, and auxiliary rotating equipment can use the relay architecture for alarm and shutdown interfacing.
- Large installations: Where the four relay outputs available through an IOC4T are insufficient, an RLC16 can expand the relay interface. Available product documentation specifically describes the RLC16 as a 16-channel relay expansion card.
Field note: If the old relay card has welded contacts or intermittent alarms, inspect the downstream trip circuit before installing the spare. A shorted suppression device, excessive inductive load, or incorrect contact wiring can damage the replacement just as quickly.

The Engineer’s Guide: Field Pitfalls to Avoid
WARNING 1 — Do not treat 200-570-000-014 and 200-570-101-013 as interchangeable.
They are associated with different generations: versus RLC16Mk2 / VM600Mk2.
How to avoid it: Identify the installed MPC4/MPC4Mk2, rack type, and complete module part number before approving the replacement.
WARNING 2 — Do not assume the relay contacts are wired identically.
Even when two cards provide 16 relay channels, terminal assignment and system architecture can differ between generations.
How to avoid it: Photograph the existing wiring, obtain the correct pinout, and verify every alarm/trip circuit before transferring conductors.
WARNING 3 — Never test a protection relay card only by watching LEDs.
A status LED proves very little about contact integrity.
How to avoid it: Test the actual relay outputs with a controlled signal and verify contact operation, reset behavior, alarm logic, and the downstream PLC/ESD/trip circuit. For a turbine trip path, perform the final test under the plant’s approved maintenance procedure.
Frequently Asked Questions (FAQ)
What is Vibro-Meter 200-570-000-014?
200-570-000-014 is the relay card used in the machinery-protection system. It provides 16 additional relay channels for alarm, trip, and protection interfacing.
What is 200-570-101-013?
200-570-101-013 is the RLC16Mk2 relay module for the VM600Mk2 generation. It also provides 16 relay outputs but belongs to the second-generation architecture.
Are 200-570-000-014 and 200-570-101-013 direct replacements?
Do not assume they are. The part numbers correspond to different generations of the platform.
The first check should be the installed protection processor:
- → investigate 200-570-000-014.
- MPC4Mk2 / VM600Mk2 → investigate RLC16Mk2 200-570-101-013.
The rack and complete system configuration still need to be verified.
How many relay outputs does the provide?
The is identified as a 16-channel relay expansion card.
That makes it particularly useful when the standard relay capacity of the installed I/O arrangement is insufficient for the required alarm and trip matrix.
What rack can RLC16Mk2 200-570-101-013 use?
Available documentation identifies the RLC16Mk2 as compatible with VM600Mk2 ABE04x racks and the ABE056 slimline rack, with control provided by the associated MPC4Mk2.
The exact rack and processor combination should still be confirmed from the installed system drawings.
What should I check when buying a refurbished ?
Ask for the complete part number and generation confirmation first. Then verify:
- PCB and connector condition.
- Relay contact condition.
- All 16 relay channels.
- Coil/drive operation.
- Normally-open/normally-closed contact behavior as applicable.
- Insulation and isolation condition.
- Rack communication/control behavior.
- Alarm and trip output testing.
For a protection application, a supplier stating only “powers on and tested” is not enough. Request the actual relay-channel test procedure and results.
Can the be used for turbine emergency shutdown signals?
It can participate in machinery-protection alarm/trip interfacing when configured as part of the appropriate protection architecture. The engineering decision depends on the plant’s protection design, relay logic, contact ratings, voting arrangement, and downstream ESD circuitry.
Do not substitute it into a certified trip chain solely because the physical card fits the rack. The complete protection function has to be validated after replacement.
