What's the VM600Mk2 Machinery Protection and Condition Monitoring System?
Time:Apr 22,2026
VM600Mk2 Overview
The VM600Mk2 rack-mounted monitoring system is an upgrade to the VM600 mechanical monitoring system, designed for rotating machinery protection and monitoring solutions in the energy industry. The VM600Mk2 is an excellent solution when a centralized monitoring system with a medium to large number of measurement points (channels) is required. It is well-suited for monitoring and/or protecting large machinery such as gas turbines, steam turbines, and water turbines, as well as generators; small machinery such as compressors, fans, motors, pumps, and propellers; and auxiliary equipment (BOP).
VM600Mk2 Monitoring System Construction
The VM600Mk2 system consists of a 19-inch rack, a rack power supply, and multiple monitoring modules. Optional configurations include relay modules, rack controllers, and communication interface modules.
1. System Racks
Two rack options are available: the VM600Mk2 system rack (ABE04x – 6U), accommodating up to twelve monitoring modules; and the VM600Mk2 slim rack (ABE056 – 1U), accommodating one monitoring module. Racks are typically installed in standard 19-inch rack-mount cabinets or chassis within a equipment room.
2. Monitoring Modules (Used in Pairs)
The VM600Mk2 offers various monitoring modules suitable for applications such as mechanical protection, condition monitoring, and/or combustion monitoring.
The MPC4Mk2 + IOC4Mk2 module (available in standard and SIL versions) supports mechanical protection and condition monitoring; mechanical protection is enabled by default, while condition monitoring is optional. The MPC4Mk2 + IOC4Mk2 mechanical protection and condition monitoring modules are designed for use with the second-generation VM600Mk2 rack-mounted mechanical monitoring system. The MPC4Mk2 is the central processing module, and the IOC4Mk2 is the input/output module. Together, these two modules provide the VM600Mk2 system with four dynamic channels and two auxiliary channels for mechanical protection, other condition monitoring, and vibration and combustion applications. The VM600Mk2 is available in a standard version (MPC4Mk2 + IOC4Mk2) and a SIL safety version (MPC4Mk2 SIL + IOC4Mk2 SIL). The SIL version is suitable for functional safety environments compliant with IEC 61508.
The XMV16 + XIO16T modules support extended condition monitoring for vibration applications.
The XMC16 + XIO16T modules support extended condition monitoring for combustion applications.
The AMC10Mk2 + IOC10Mk2 analog monitoring module supports application status monitoring of a large number of slowly changing analog signals, such as temperature and other process variables; mechanical protection and condition monitoring functions are available by default.
3. Relay Module
The RLC16Mk2 relay module (standard and SIL versions) is an optional module used to provide additional relays when the four user-configurable relays of the MPC4Mk2 + IOC4Mk2 module or the two user-configurable relays of the AMC10Mk2 + IOC10Mk2 module are insufficient to meet application requirements.
4. Rack Control and Communication Interface Module
The CPUMMk2 + IOCNMk2 rack controller and communication interface module is an optional module used to provide additional functions of the VM600Mk2 system, such as fieldbus communication; module data aggregation, processing and sharing; rack and/or fieldbus communication redundancy; front panel alarm reset (AR); MPS rack (CPUx) safety; and system event and measurement event logging.
5. Rack Power Supply Module
RPS6U Mk2 Rack Power Supply is available in AC input versions (115/230 VAC or 220 VDC) and DC input versions (24 VDC and 110 VDC). It provides overvoltage, short-circuit, and overload protection for the VM600 Mk2 monitoring system. One RPS6U Mk2 rack power supply can power an entire rack of modules (cards), and two RPS6U rack power supplies can achieve rack power redundancy.
