Product Introduction
VIBRO-METER IOC4T 200-560-000-111 is a rear input/output module for the VM600 and VM600 Mk2 machinery protection systems. It serves as the signal interface for the MPC4 machinery protection card, providing direct termination for vibration sensors, tachometer inputs, buffered outputs, relay outputs, and digital I/O signals.
The IOC4T is mounted at the rear of the VM600 rack and operates in slave mode with a paired MPC4 card installed in the front slot. It supports 4 dynamic signal inputs and 2 tachometer inputs, buffered “raw” sensor signal outputs, 4 software-configurable local relays, and digital I/O channels that can connect to IRC4/RLC16 relay cards or external control systems. This module is commonly used in turbine, compressor, generator, and pump protection applications across power generation, oil & gas, and petrochemical facilities.
The IOC4T family includes several part-number variants. The exact revision, digital I/O configuration, and relay options for 200-560-000-111 should be confirmed against the module nameplate and official Vibro-Meter documentation before installation.

Quality Control Process
Each unit begins with a visual inspection of the terminal blocks, rear connectors, PCB, and backplane contacts for corrosion, bent pins, or thermal stress. The IOC4T is then seated into a compatible VM600 rack to verify mechanical fit and backplane engagement.
The module is paired with a compatible MPC4 card to confirm proper card-pair recognition. Power is applied through the rack supply, and initialization indicators are checked for proper startup behavior. Dynamic and tachometer input channels are verified with a precision signal source and Fluke multimeter to confirm input response, noise floor, and isolation. Relay outputs and buffered signal outputs are tested where applicable. Final packing uses anti-static bags, foam inserts, and sealed cartons to protect the module during shipment.
Replacement Pitfall Guide
❗ Confirm the exact part number and revision. The IOC4T family includes multiple variants such as 200-560-000-016, 200-560-101-015, 200-560-000-111, and 200-560-101-017. Hardware revision, relay configuration, or digital I/O options may differ between variants.
❗ Verify the paired MPC4 card. The IOC4T cannot operate alone—it must be paired with a compatible MPC4 machinery protection card. Installing it behind a CMC16, XMV16, or other monitoring card will not produce correct operation.
❗ Revalidate alarm and relay mapping. After replacement, all relay outputs, digital I/O assignments, and alarm trip logic must be reconfirmed in MPSx software. Incorrect relay mapping can prevent proper trip action during a machinery fault.
❗ Check sensor wiring and terminal assignments. IOC4T uses screw-terminal connections for sensor inputs, buffered outputs, and relay signals. Reversed polarity, loose terminals, or poor shielding can introduce noise or cause false trips.
Keep these in mind and you’ll cut 90% of rework time.
