Siemens 7MH4960-4AA01 SIWAREX WP241 Pesage électronique à bande transporteuse

Description

The Siemens 7MH4960-4AA01 is a high-precision SIWAREX WP241 electronic weighing module designed for belt scale applications. As a single-channel weighing transmitter, it facilitates the connection of strain gauge load cells in full-bridge configuration with a sensitivity range of 1-4mV/V. This module is engineered for seamless integration into the SIMATIC S7-1200 automation system but also supports stand-alone operation, providing flexible deployment for continuous weighing processes. The unit features integrated digital and analog I/O, including 4 digital inputs, 4 digital outputs, and 1 analog output (0/4-20mA), alongside built-in RS485 and Ethernet interfaces for robust industrial communication.

Installation Guidelines

• Ensure proper grounding of the module to the mounting rail to minimize electrical noise.
• Use shielded cabling for load cell connections to prevent signal interference.
• Maintain adequate clearance for ventilation around the module housing in the control cabinet.
• Verify correct polarity when wiring the 24V DC power supply to the module terminals.
• Use twisted-pair wiring for RS485 communication lines to ensure signal integrity over long distances.
