Müller Digital Indicators DC Current/High DC Voltage Standard Signal (M3-H)
Product Code: M3-H
Manufacturer: Müller
This Müller Digital Indicators DC Current/High DC Voltage Standard Signal (M3) high-performance display unit features a wide digit range from -19999 to 99999 with a red LED display, and optional green, orange, blue, or tricolour versions. With a 120 mm installation depth (excluding the plug-in screw terminal) and a multi-voltage power supply (100–240 VAC), it’s suitable for various industrial applications. The device offers min/max memory with permanent display, 30 adjustable support points, flashing alerts for threshold breaches, and zero keys for functions like Hold, Tara, setpoint setting, and alarm triggering. It supports volume measurement, advanced math functions (e.g., square root, reciprocal), sliding averaging, and brightness control. The unit features IP65 front protection, a programming lock, and plug-in screw terminals. Optional features include 2 or 4 relay outputs, 8 PhotoMos outputs, up to 2 scalable analog outputs, galvanically isolated digital inputs, and RS232/RS485 interfaces. A PC-based configuration kit is available, and models for extreme temperatures (-20°C to 60°C or -40°C to 70°C) can be supplied on request.
