Vibro-Meter IOC4 Mk2 600-043 VM600Mk2 IOC4Mk2 input/output module
Product Description
The Vibro-Meter IOC4 Mk2 600-043 is the standard VM600Mk2 IOC4Mk2 input/output module used with an MPC4Mk2 processing module. It places the field-side connectors at the rear of the VM600Mk2 rack and routes measurement, relay, analog and digital interface signals to the processing electronics.
For IOC4 Mk2 600-043, the 600-043 ordering number corresponds to the IOC4Mk2 standard module family whose underlying version is 620-024-100-1Hh. J1 accepts dynamic and auxiliary analog inputs, J2 carries buffered outputs, DSI signals and analog DC outputs, and J3 carries the four user relays and the common fault relay.
For IOC4 Mk2 600-043, the IOC4Mk2 also stores a non-volatile copy of the MPC4Mk2 + IOC4Mk2 configuration. Its optional rear Ethernet location can be used instead of the front MPC4Mk2 LAN connector when the specified hardware and software versions are present.

Communication and Connectivity — IOC4Mk2 Interfaces
IOC4 Mk2 600-043 provides the rear-rack signal and communication boundary for the MPC4Mk2 pair.
J2 outputs and controls
J2 carries buffered raw outputs, auxiliary TTL pulse outputs, DSI control signals and analog DC outputs.
J3 relay contacts
J3 carries the RL1–RL4 user relays and the common circuit-fault relay contacts.
Diagnostics and Protection — Relay Status
The IOC4Mk2 participates in the module-pair status and configuration path used by VM600Mk2 protection systems.
Configuration retention
Non-volatile memory stores a copy of the module configuration for reconfiguration after an MPC4Mk2 replacement.
Fault relay path
The FAULT relay provides a common circuit-fault indication alongside the four user-configurable relays.
LAN status
The rear LAN link and activity LEDs show the status of the IOC4Mk2 Ethernet communication path.
Common Questions
Which MPC4Mk2 partner and rack position are required for Vibro-Meter IOC4 Mk2 600-043?
Use Vibro-Meter IOC4 Mk2 600-043 with the specified MPC4Mk2 processing module and matching VM600Mk2 rack position. Confirm the rear connector orientation and card depth before wiring, because IOC4Mk2 provides the field interface rather than the protection algorithm.
Which termination order keeps J1, J2 and J3 separate on Vibro-Meter IOC4 Mk2 600-043?
Keep the connector groups separate on Vibro-Meter IOC4 Mk2 600-043: J1 is for dynamic and auxiliary analog inputs, J2 is for buffered/DSI/analog outputs, and J3 is for relays. Label the complete cable group before insertion so a relay or fault contact is not landed on an analog pin group.
When should the rear LAN be used instead of the front connector with Vibro-Meter IOC4 Mk2 600-043?
Use only the permitted front or rear Ethernet location for Vibro-Meter IOC4 Mk2 600-043 after checking the hardware, firmware and VibroSight version. The two locations are alternatives, not simultaneous network ports, so the unused path must remain disconnected.
How does the non-volatile configuration copy help when replacing Vibro-Meter IOC4 Mk2 600-043?
Retain the configuration copy stored by Vibro-Meter IOC4 Mk2 600-043 and compare it with the MPC4Mk2 setup before re-commissioning. The copy supports restoring the module-pair arrangement, but it does not remove the need to verify firmware and field termination.
How can a missing FAULT or user-relay transition be isolated on Vibro-Meter IOC4 Mk2 600-043?
Trace the J3 COM/NC/NO wiring and the MPC4Mk2 relay assignment first for Vibro-Meter IOC4 Mk2 600-043. Then check the common circuit-fault path and configuration, because the IOC4Mk2 routes the relay contacts but does not create the alarm logic by itself.
What rear clearance is required to remove the connectors from Vibro-Meter IOC4 Mk2 600-043?
Leave the specified rack depth and cable bend space behind Vibro-Meter IOC4 Mk2 600-043 before closing the cabinet. Crowded J1/J2/J3 wiring can prevent a full connector lock and can create intermittent signals that look like an MPC4 processing fault.
