A compact digital loadcell amplifier card with digitally derived analogue output for current loop and voltage measuring systems. The TLB includes localised controls and a 6 segment display for easy setup in the field. While taking measurements the display provides a 5½ digit monitor of the load conditions experienced by the TLB to allow for easy system diagnostics. The TLB offers 3 relay outputs to drive trips and alarm indicators, and 2 optoisolated inputs for remote control of the amplifier. Versions are available with a wide range of communications options for CANopen, DeviceNet, CC-Link, Profibus, Modbus, Ethernet, Profinet, EtherCAT, POWERLINK and SERCOS III.
