Physical Mapping
What is the specific rack orientation for the IOC4T?
The IOC4T is a rear-panel interface exclusively paired with the MPC4 machinery protection card. Installation must be in the slot directly behind the MPC4 within an ABE04x or ABE056 rack. It seats onto the backplane via two high-density connectors, bridging the field wiring to the front-end processing logic.

Interface Logic
How is data exchanged between the I/O stage and the MPC4?
The card operates in Slave Mode. It communicates over the P2 Industry Pack (IP) interface. This high-speed link allows raw dynamic data and tachometer pulses to reach the MPC4 for real-time analysis, while returning processed alarm states and analog values to the IOC4T terminals.

Analog Output Specs
How do I switch between voltage and current outputs for DCS loops?
The IOC4T provides four dynamic signal channels. For 0 to 10 V outputs, it utilizes on-board DACs. If your control system requires 4 to 20 mA current loops, you must manually configure the on-board jumpers to engage the voltage-to-current converters.

Field Termination
What is the standard for connecting raw sensors?
Field wiring lands on screw-terminal strip connectors at the rear of the rack. These terminals accept transmission cables from the measurement chain--typically vibration sensors, accelerometers, or signal conditioners. The terminal block is the primary interface for all I/O between the VM600 and the plant DCS/PLC.

Alarm Propagation
How are discrete alarms handled beyond the local relays?
Aside from local hardware, the IOC4T pushes 32 digital alarm signals directly to the rack backplane. These are jumper-selectable and intended for harvesting by expansion cards like the RLC16 relay card or the IRC4 intelligent relay card, allowing for complex multi-point shutdown logic.
|
Local Relay Assignment
Can I use the IOC4T relays for system health monitoring?
Yes. The four local relays are software-configurable. They are commonly assigned to mission-critical states such as Sensor OK (integrity check), Alarm, and Danger (trip) levels, or to signal a dedicated MPC4 Fault if the protection logic self-diagnoses a failure.

Electrical Hardening
How does the module handle signal surges in noisy environments?
The IOC4T is the primary barrier against EMI and signal surges. All input/output paths are hardened to meet strict EMC (Electromagnetic Compatibility) standards. This prevents high-frequency interference from motor drives or switchgear from corrupting the raw dynamic vibration data.
|
Signal Processing Loop
What is the path for raw dynamic and speed signals?
Raw inputs (vibration/speed) enter the IOC4T, pass through the backplane to the MPC4 for TMR or standard processing, and are then routed back to the IOC4T. The module then outputs these as "clean" processed signals via the DACs or current converters for external monitoring or historian logging.
