KFM 903701 Temperature Controller | 2×Pt100 | 3 Relay Outputs | 100–250 VAC | Industrial DIN Controller

New. Without original box.

The KFM 903701 Temperature Controller is a robust and precise industrial control device developed by KFM Regelungstechnik GmbH (Germany) for advanced temperature monitoring and regulation tasks. Designed for industrial environments, this controller supports two Pt100 DIN temperature sensors with a wide measurement range from −200 °C to +800 °C, ensuring high accuracy and reliability in thermal processes.

The device features configurable analog inputs (0–4…20 mA and 0–2…10 V), allowing flexible integration into existing automation systems. With three relay outputs, the controller can manage heating, cooling, alarm signaling, or other control functions directly.

A wide 100–250 VAC power supply range enables global industrial use, while the IP54 front protection ensures durability in harsh control cabinet environments. The integrated USB / KFM 2.0 service interface allows convenient configuration, diagnostics, and maintenance.
