Product Overview

The C0136HZ is an official factory complete replacement kit for the M/40K pneumatic relay core component of the classic Foxboro I/A Series distributed control system, widely used in petrochemical plants, thermal power stations, pulp and paper factories, and large refining process units.

It undertakes the critical task of converting electronic DCS control output signals into pneumatic air pressure signals to drive field pneumatic regulating valves, actuators and positioners, serving as the key electro-pneumatic conversion link between the digital DCS controller and traditional pneumatic field instrumentation. This integrated kit contains the main pneumatic relay body, mounting sockets, terminal wiring accessories and sealing fittings, solving the core maintenance pain point of aging I/A DCS systems: worn relay diaphragms, air leakage, slow response and unstable valve positioning caused by long-term service.
