Signal Converters & Isolators Threshold Relay PXL-10 DESCRIPTION OPERATION A threshold relay for the monitoring or control of common types of process signals. The process signal to be monitored is selected on the front panel and the threshold value is also adjusted via a setpoint potentiometer on the front of the relay. As the input signal attains the threshold plus the hysteresis the output relay energises. When the input signal drops and passes the threshold, minus hysteresis, the relay de-energises. The hysteresis is adjustable on the front, ±0,5 - 20%. By strapping 2 terminals, the relay can be inverted. A red LED indicates if the relay is energised. There is also a latch function where the relay after energising will remain energised, regardless of input, until the latch jumper or the operating voltage is disconnected. Typically used in safety circuits. Output signal supply hysteresis setpoint inv latch Features • Input 0 - 5V/0-10V/-10-+10VDC/0-20/4-20mA in one version. • Adjustable setpoint. • Hysteresis adjustable ±0,5-20%. • Automatic locking (Latch). • Inversion of relay function. • Output SPDT. • Operating voltage 24VDC, 24/115VAC or 24/230VAC.
