TLM8 Multi-input digital loadmeter

TLM8 Multi-input digital loadmeter

A compact solution to interfacing multiple parallel connected loadcells for force measurement and weighing applications. The TLM8 has a block of terminals that acts like a junction box to connect up to 8 loadcells in parallel. Additionally the TLM8 allows for span equalisation of the individual loadcell inputs, to correct for any output differential between the loadcells. The TLM8 offers 5 relay outputs to drive trips and alarm indicators, and 3 optoisolated inputs for remote control of the loadmeter. Versions are available with a wide range of communications options for CANopen, DeviceNet, CC-Link, Profibus, Modbus, Ethernet, Profinet, EtherCAT, POWERLINK and SERCOS III.
