Configured for signal acquisition and data processing in distributed control systems, the YOKOGAWA MDK1*B (MDK1*B) Control System Module provides direct physical and electrical execution for process automation platforms.

Hardware Specifications

Channel-to-Channel Isolation and Loop Protocol Architecture

The module incorporates channel-to-channel optical and galvanic isolation circuitry designed to eliminate ground loops and electromagnetic interference across multi-variable process measurement loops. Signal conditioning stages execute analog-to-digital conversion with 16-bit resolution and a 100 ms sampling rate across thermocouples, RTDs, strain gauges, load cells, pressure transmitters, and flow meters. Integrated communication modules support 4-20 mA loop protocols and internal bus connectivity, ensuring deterministic data exchange and robust diagnostic reporting to central control systems.

Frequently Asked Questions

Q: What power supply voltage is required to operate the MDK1*B module?

A: The module requires a nominal 24 VDC power supply input during operational states.

Q: What is the measurement resolution and sampling rate of the module?

A: The hardware delivers a 16-bit resolution with a 100 ms sampling rate across configured inputs.

Field Installation Guidelines

Mount the MDK1*B module securely onto designated node unit slots or DIN rails, ensuring proper backplane connector engagement and mechanical fastening. Terminate field sensor and transmitter wiring into terminal blocks using shielded twisted-pair cables, ensuring shield drain wires are grounded to the designated cabinet earth terminal. Verify power supply voltage levels and check terminal connections prior to system energization.
