RLC16MK2 provides 16 user-configurable relays and diagnostics with system-wide safety line to dirve all system relays and analog outputs to a safe state.

Besides the standard version and there is a SIL safety version RLC16MK2 SIL.

The RLC16MK2 supplements the standard IOC4Mk2—which offers only four relays—by providing high-density, high-reliability contact outputs designed for safety interlocking and alarm control in critical rotating machinery.

 Meggitt products are widely used in high-tech sectors; here is a brief overview of several application scenarios:

Power generation: Multi-parameter alarm and trip interlock systems (monitoring shaft vibration, axial displacement, differential expansion, and rotational speed) for gas and steam turbines, ensuring safe unit shutdown with SIL 2 certification.

Hydropower units: Low-frequency vibration monitoring (starting from 0.1 Hz), alarms for "rough load zone" operating conditions, and interlock control for guide vanes and governors.

Nuclear and thermal power plant auxiliaries: Multi-channel condition monitoring, alarms, and interlock protection for critical auxiliary equipment such as feedwater pumps, fans, and compressors.

Oil and gas industry: Multi-parameter interlock systems (monitoring vibration, temperature, and pressure) for centrifugal and reciprocating compressors, including anti-surge and overspeed protection.

Offshore platforms and refining/petrochemical plants: Remote alarm and shutdown control for critical rotating equipment in explosion-proof environments.

High-value industrial equipment: Multi-channel rapid cutoff upon limit violation for systems such as aero-engines and gas turbine test stands.

Safety Instrumented Systems (SIS)

Replaces traditional hard-wired relays to enable centralized management and diagnostics of safety functions for critical equipment.

Integrates with the VM600 Mk2 system to simultaneously drive all relays and analog outputs to a safe state in the event of a fault.
