Maximum Control, Miniature Size

For PLC systems that require weight data from a scale, Rice Lake’s compact SCT-30 transmitter delivers equivalent signal-conditioning function without the cost or bulk of a full-size weight indicator/controller.

Rice Lake's SCT-30 models are DIN-rail mountable within a cabinet or control panel, where they convert a scale’s load cell signal to serial or analog output. Technicians and operators find the analog output signal particularly useful for monitoring hopper filling and discharge. Unlike many other signal transmitters, Rice Lake SCTs have their own integrated display, with annunciators for unit and weighing status, and push buttons or toggle switch and digital rotary for zero, tare and setpoint entry—ultimately simplifying scale setup, calibration and operation.
