Information
For PLC systems that require weight data from a scale, Rice Lake’s compact SCT-20 transmitter delivers equivalent signal-conditioning function without the cost or bulk of a full size weight indicator/controller.
Each Rice Lake SCT-20 is DIN-rail mountable within a cabinet or control panel, where it converts a scale’s load cell signals to analog output, serial output, or a specific network protocol. Unlike many other signal transmitters, Rice Lake’s SCT-20 has its own .3 inch weight display, with annunciators for unit and weighing status, and push buttons for zero, tare and setpoint entry—simplifying scale setup, calibration and operation.
