Construction and Materials
The module uses a molded plastic housing, which keeps the unit lightweight and durable. Meanwhile, terminal blocks accept standard thermocouple wiring without specialized tools. The rack mount design fits Yokogawa chassis, so replacements require minimal downtime.
Interface and System Compatibility
This input module integrates with Yokogawa field control systems and related I/O racks. Additionally, galvanic isolation separates channels to prevent ground loops. Therefore, users maintain signal accuracy even in electrically noisy plant environments.
Installation Guidelines
Mount the unit within a compatible rack and verify seating before power-up. Furthermore, route thermocouple wiring away from high-voltage cables to reduce interference. Correct grounding practice improves measurement stability, so follow plant standards carefully.
