Product catalog summary

Input/Output Modules
Input and output modules are designed to extend digital and analog I/Os in switchgear when existing protection relays are insufficient. They handle analog or binary signals from switches, buttons, and sensors, and control actuators. The Modbus RTU interface allows individual reading of inputs and setting of output relays. Key models include UG 9460 with 8 digital inputs and 4 relay outputs, and UG 9461 with 8 analog inputs, 2 analog outputs, and 2 configurable measuring inputs.

Insulation Monitoring for IT Systems
The RN 5897 insulation monitor from the VARIMETER IMD series is tailored for modern power supplies, accommodating high leakage capacitance up to 1000 μF. It is suitable for ungrounded AC, DC, and AC/DC networks, offering preventive fire and plant protection with easy parameter adjustments.

Fault Current Detection
The RN 5883 residual current monitor from the VARIMETER RCM family detects DC and AC fault currents in earthed networks using the ND 5015 transformer. It features simple adjustments, broken wire detection, four measurement ranges (10 mA - 3 A), and an adjustable pre-alarm.

Soft Start of Motors
The UG 9410 motorstarter from the MINISTART series offers up to 7 functions in a compact design, facilitating soft start, stop, reversing, and protection of 3-phase motors. It supports Modbus RTU communication, reducing wiring and enhancing diagnostics, thus extending plant lifespan.

VARIMETER Series with UL-Listing
The VARIMETER series relays monitor voltage parameters and phase conditions in systems without needing auxiliary power. They offer simple adjustments and selectable monitoring functions, aiding in preventive maintenance to avoid costly damages.

Hybrid Relay
The IK 3070/200 hybrid relay combines relay and semiconductor technologies for efficient switching, minimizing surge voltages and currents. It is space-saving and suitable for high inrush current loads, ensuring long service life.
