Yokogawa Electric Corporation C3GD20149J Terminal Module

The Yokogawa STA4S-10 Style S1 Terminal Module (C3GD20149J) is a pressure‑clamp terminal block that directly interfaces field wiring with Yokogawa PLC and DCS I/O modules, delivering a secure, organized termination for control‑system wiring. The “-10” suffix indicates built‑in surge absorption for enhanced signal protection in industrial environments, and the module supports up to 16 high‑density channels using a pressure‑clamp or screw terminal interface. Key specs include a voltage rating up to 24–60 VDC (application dependent), a per‑channel current rating up to 4 A, isolation around 500 VAC, and an operating temperature range of roughly -20°C to 60–85°C, with mounting options on DIN rails or panel assemblies. Commonly deployed in CENTUM VP and ProSafe‑RS systems, it provides the interface between sensors, transmitters, and switches and I/O modules, simplifying panel wiring and maintenance across oil and gas, chemical processing, power generation, and water treatment.
