The SC-4 Signal Conditioner unit is a four station system used to monitor temperature. This system is used with Maxi-Tronic HB Bearing Temperature, RB Belt Misalignment, and other Maxi-Tronic temperature sensors.
The SC-4 will interface temperature, alignment and most PTC sensors to a PLC or computer system.
Each of the sensor inputs are wired directly to the SC-4 unit and controls the OFF and ON action of a 3 amp at 120 VAC relay.
> When the sensor is connected and the temperature is below its TURN ON range, the GREEN LED will light and the relay will be closed.
> When the temperature exceeds the TURN ON point, the RED LED. will turn ON and the GREEN LED will turn OFF. The output relay will switch to the OPEN position signaling a present change in the temperature of the sensor.
> If the sensor should be damaged or wire leads to the sensor should open, the RED LED will turn ON and the output relay will switch to the OPEN position.
Continuous failsafe protection: If the sensor or wiring is damaged or shorted; the RED LED will turn on and the output relay will switch to the open/alarm position.
