Stork Tronic – ST48‑WHDVM.04FP – Differential PID Temperature Controller, 24 VDC

The ST48‑WHDVM.04FP from Stork Tronic (formerly Schimpke) is a compact 48 × 48 mm panel-mount PID differential temperature controller with dual 3‑digit LED displays and three relay outputs. Powered by 12–36 V DC (or 12–24 V AC), it monitors a primary and secondary temperature sensor (Pt100) and controls processes via three configurable relays (main setpoint, secondary setpoint, limit). Programmable PID, hysteresis, alarm settings and analog output enhance flexibility for industrial temperature regulation.
