Built‑in function

C0136HZ control relay replacement assembly receives logic drive signal from Spec‑200 rack backplane bus and drives built‑in electromechanical relay to complete dry‑contact switching. It outputs interlock,alarm and auxiliary control signals for field‑side devices. Internal RC surge‑suppression circuit absorbs coil reverse electromotive force and protects internal rack circuit. Front‑panel LED visually reflects relay actuation state for quick on‑site troubleshooting,widely applied for safety interlock and alarm‑logic loops in petrochemical,chemical and power‑plant Spec‑200 DCS cabinets.

Product Brief

C0136HZ belongs to Foxboro Spec‑200 legacy DCS logic‑output spare‑part family,obsolete original plug‑in automation component. Must be fitted in matching Spec‑200 instrument rack with correct field contact‑loop wiring. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
