Yokogawa MRT*A CENTUM/ProSafe Terminal Board Interface
The Yokogawa MRT*A, also cataloged as the MRT*A Terminal Board, operates as a dedicated hardware component for field signal termination and wiring distribution within Yokogawa CENTUM VP, CS 3000, and ProSafe-RS systems. It connects field-side analog and digital signal channels directly to Yokogawa FIO AI, AO, DI, and DO cards.
Suffix Breakdown & Model Matrix
The MRT*A hardware designation uses suffix coding to specify terminal connectivity styles, mounting options, and channel density configurations:
- MRT: Base Model Designation (Field Signal Terminal Board Interface)
- *A: Revision and Option Code (Designating terminal connection style and point capacity)
- Capacity Variants: 16-point, 32-point, or 64-point configurations (model-dependent)
- Terminal Variants: Screw-type or spring-clamp wiring terminal assemblies

Channel-to-Channel Isolation & Reinforced Insulation
The MRT*A terminal interface uses reinforced insulation barriers to separate field instrument wiring from sensitive system-side I/O card electronics. The assembly suppresses industrial electromagnetic noise across high-density 16, 32, or 64-point configurations, supporting maximum current loads up to 5 A per terminal on 24 VDC digital channels. This physical shielding prevents common-mode voltage spikes and field earth loops from destabilizing connected control channels.
Frequently Asked Questions
Q: What mounting choices are available for integrating the MRT*A inside a control cabinet?
A: The board supports standard TS35 DIN-rail snapping or direct panel-mount installation depending on cabinet layout specifications.
Q: What wiring options are available on the MRT*A field connection interface?
A: Hardware variants accommodate either screw-type or spring-clamp terminals to secure conductors for up to 64 I/O points.
Q: What is the maximum current rating supported per terminal point?
A: Individual terminals support up to 5 A maximum continuous current, suitable for 24 VDC discrete switching lines.
Field Installation Guidelines
- Mount the MRT*A unit onto a standard DIN rail or panel surface using appropriate mounting hardware before connecting signal cables.
- Strip field signal wire ends according to terminal specifications and secure them into screw or spring-clamp terminals.
- Keep field signal conductors and high-voltage power distribution lines in separate wire ducts to maintain EMC performance.
- Connect cable drain shields directly to a dedicated ground bar to preserve the signal integrity of the reinforced insulation design.
- Verify environmental cabinet conditions remain within 0 to 55 deg C and 5 to 95% non-condensing relative humidity.
