Sig-Con™ Limit Alarms- Series SC
DC, RTD or Thermocouple Input,Configurable Ranges
Series SC Limit Alarmsare ideal for indicating production line faults, process upsets, equipment failures, or control system abnormalities. Units accept DC, RTD, or thermocouple input and provide independent SPDT relay output per setpoint. Limit alarms feature programmable HI or LO and failsafe or non-failsafe adjustable setpoints. Bright LEDs indicate line power, input signal status and relay state.
