Selection and ordering data
•
For temperature monitoring with resistance sensors or
thermocouples
•
Temperature range dependent on sensor type
•
Wide voltage range versions are electrically separated
• Non-volatile
•
Short-circuit and open-circuit detection in sensor circuit
•
Digitally adjustable, with illuminated LCD
•
Overshoot, undershoot or range monitoring adjustable
•
Exact sensor type can be set
•
2 separately adjustable threshold values
•
1 hysteresis applies to both thresholds (0 to 99 K)
•
1 delay time applies to both thresholds (0 to 999 s)
•
Adjustable open/closed-circuit principle
•
Adjustable manual/remote RESET
•
Permanent display of actual value in °C or °F and tripping
state
•
1 CO contact each per threshold value
•
1 NO for sensor monitoring
