The PLC output option consists of a circuit board and a cable to connect to your PLC. Since 24VDC power is usually available at a PLC, the drumalarm or tank alarm is powered by the available 24VDC.
The circuit board inside the electroncis enclosure allows for a local buzzer and LED, and control as well as at your PLC.
Different behaviours are set with jumpers; you can select N.O or N.C. relay output. You can choose if there is a snooze alarm or not, (after pressing the button to silence the buzzer). Or if the LED should continue to blink after the silencing button is pressed. Also the orientation of the alarm can be changed from high to low.
The drumalarm or tank alarm is connected to your PLC by a 8-conductor cable with thick 0.032" PVC insulation. Default length is 10 ft. Longer lengths can be ordered by the foot.
