200-560-000-016 IOC4T Input/Output Card is a signal interface card used in the machinery protection system. It is mainly installed in conjunction with the MPC4 machinery protection card within the VM600 rack system and is used for interface processing of vibration signals, rotational speed signals, and alarm outputs.
This module is installed at the rear of the MPC4 card and is used to expand the input and output of the vibration monitoring system, including dynamic vibration channels, tachometer speed input, relay output, and analog output interfaces. IOC 4T is commonly used in rotating machinery monitoring projects such as steam turbines, gas turbines, compressors, and generator protection systems.
Before purchasing, it is necessary to confirm the complete order number to ensure the supply of the corresponding products.

In the Monitoring rack, 200-560-000-016 IOC4T is responsible for converting the signals from on-site sensors to the monitoring system and transmitting alarm status, relay signals, and analog output to PLC, DCS, or external protection systems. The module supports 4 dynamic input channels and 2 speed input channels, which can be used for shaft vibration, shell vibration, displacement, and speed measurement chains.
This card applies to:
VM600 machinery protection systems
Vibro-Meter monitoring racks
API 670 vibration monitoring applications
Industrial rotating machinery protection systems
Oil & Gas machinery monitoring
Power plant turbine monitoring systems
In the input/output interface section, 200-560-000-016 IOC4T adopts an EMI/EMC protection design, which is used to reduce:
Electromagnetic interference
Ground noise
Signal distortion
Long-distance transmission interference
This type of structure is commonly found in:
Power plant turbine cabinets
Oil & Gas compressor systems
High-voltage industrial environments
Rotating machinery monitoring systems
The IOC4T is mainly used as an interface expansion module for the MPC4 machinery protection card. This module is installed at the rear of the VM600 rack and forms a complete machinery protection channel together with the front MPC4 card.
In the large-scale rotating equipment monitoring system, the on-site vibration signals usually come from:
Proximity probes
Velocity sensors
Accelerometers
Tachometer sensors
IOC4T is used to receive and process these input signals, and at the same time, it outputs the monitoring results to:
DCS systems
PLC systems
Alarm systems
Turbine control systems
This Input/Output Card supports:
Dynamic vibration input
Speed input, Relay alarm output
Buffered output
Analog signal output
Dynamic Signal & Tachometer Processing
IOC4T supports 4 dynamic measurement channels, which can be used for vibration signal acquisition.
These channels are typically connected as follows:
TQ series proximity systems
Velocity transducers
Acceleration sensors
In the API 670 vibration protection applications, the rotational speed signal and the vibration signal usually need to be processed synchronously. Therefore, IOC4T will be used together with MPC4 in the complete mechanical protection system architecture.
Analog Output & Relay Interface
IOC4T provides:
0–10 V analog outputs
4–20 mA signal outputs
Relay output interfaces
These interfaces are used to transmit vibration monitoring data to an external system.
Hot-Swappable Card Structure
IOC4T adopts the modular rack architecture from the VM600 system and supports online plug-and-play maintenance.
In some system configurations, the on-site engineer can operate without shutting down the entire rack.
