Description:

Siemens 7MH4960-4AA01 is a single-channel weighing electronics module, designated as SIWAREX WP241, specifically designed for conveyor belt scales and solids flowmeter applications using analogue load cells or strain gauges (full bridges). It can be integrated with SIMATIC S7-1200 PLCs or operated as a standalone device.
