Dold Monitoring Relay, DPDT, DIN Rail Mount, 230V AC Motor Control with Thermistor Protection MK9163N.12/100 AC50/60Hz 230V

The Dold MK9163N.12/100 AC50/60Hz 230V Monitoring Relay is engineered for precise motor control applications using thermistor input for temperature and sensor circuit monitoring. This DPDT relay easily mounts on DIN rails, facilitating integration into control panels and industrial automation systems.

Equipped with a closed circuit current principle, the output relay remains inactive during fault conditions, enhancing operational safety. LED indicators provide clear status of auxiliary voltage and contact position, aiding quick diagnostics.

The relay features dual changeover (DPDT) output contacts rated at 5A, supporting a switching voltage of 230V AC. It is designed to detect temperature limit exceedance, wire breakage, and short circuits within sensor circuits, helping to protect motors from damage due to thermal faults.

Compact with an overall width of 22.5 mm, height of 90 mm, and length of 102 mm, the device fits standard DIN rail installations. It operates reliably over a temperature range from +60°C to 60°C and is rated with an IP40 protection class, suitable for various industrial environments.

Compliance with multiple international safety and quality standards including DIN 46 228 series, EN 60947-5-1, IEC/EN 60 947-5-1, and UL Subject 94 ensures dependable and standardized performance in electrical monitoring and motor protection roles across manufacturing, automation, HVAC, and industrial process control applications.

The relay mounts on standard DIN rails for flexible installation. Closed circuit current principle prevents relay activation on faults. LED indicators for auxiliary voltage and contact position provide visual status. Two changeover output contacts rated at 5A and 230V AC voltage.

Thermistor input allows detection of temperature limits and sensor circuit faults. Compact size and IP40 rating for durable industrial use. Extensive international standard approvals guarantee product reliability. Ideal for industrial automation, electrical control, HVAC, and manufacturing process protection.
