Limit Value Monitor DG 3101
Economical Monitoring of Standard Signals with one Relay Output
The Limit Value Monitor DG 3101 is used to monitor measured values in 0(4) ... 20 mA and 0 ... 10 V standard signal circuits. A transmitter supply +Us is provided for the operation of 2-wire transmitters.
- Easy configuration on front panel
Operating mode switchable via DIP switch, switch point and hysteresis adjustable with potentiometer - Status indication by LED
Easy monitoring and switching point adjustment - True 4-port separation
Protection against erroneous measurements due to parasitic voltages or ground loops - Protective Separation acc. to EN 61010
Protects service personnel and downstream devices against impermissibly high voltage - High reliability and noise immunity
No microprocessor, no integrated software - Extremely slim design
12.5 mm slim housing for a simple and space saving DIN rail mounting - 5 Years Warranty
Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant
The switching output can be configured with the analog control electronics as MIN or MAX alarm in open-circuit or closed-circuit operation.
All setting elements are located behind the openable front cover and can also be operated when the unit is mounted. The switching point and the switching hysteresis can be adjusted with potentiometers. The monitoring state is indicated by a yellow LED.
The relay changeover contact switches high power loads up to 6 A.
The Protective Separation and the 24 V DC power supply makes the DG 3101 universally applicable for all measurement and industrial applications, as well as for building automation.
