Motorized Valve PID Controllers ECV1 Series

Motorized Valve PID Controllers ECV1 Series

The ECV1 single-channel PID controller with universal inputs is applied across various industries, municipal, and agricultural automated control systems, and is designed for:
   — Operating motorized control valves, dampers, and electric actuators via 3-point floating (Open/Close) discrete control or 0/4…20 mA and 0/2…10 V analog signals.
   — Temperature measurement using thermocouples (TCs) according to GOST R 8.585-2001 and resistance temperature detectors (RTDs) according to GOST 6651-2009.
   — Measuring standard DC current and voltage signals and scaling them into user-defined engineering units (°C, %, bar, m, kgf/cm², etc.).
