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. The 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. This significantly simplifies scale setup, calibration and operation.
