SIGNAL CONDITIONING TRANSMITTERS
Control in miniature
For PLC systems that require weight data from
a scale, Rice Lake’s compact SCT transmit
ters deliver equivalent signal-conditioning
function without the cost or bulk of a full
size weight indicator/controller.
Each Rice Lake SCT 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 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.
Standard Features
• Powers up to eight load cells in parallel (with a 24 bit A/D converter)
• RS-485 or RS-232 serial output, supports ASCII and Modbus RTU
• 16-bit analog output resolution
• Diagnostic message for load cell disconnect and over capacity errors
• Analog outputs for displayed weight of 0-20 mA, 4-20 mA, 0-10 V, 0-5 V
or +/-10 V and +/-5 V, selected as voltage or current, can track positive
or negative weight values
• Two digital inputs that can be set as gross/net, zero, peak weight or print
• Three dry contract relay outputs capable of driving up to 150 ma at 115 VAC
• Single channel indicator
