Analogue Inputs 0-20mA, Digital Inputs

  • Two analogue inputs to detect a direct-current signal in between 0 and 20 mA
  • Two digital inputs
  • 12-24 Vdc/Vac supply
  • RF power amplifier: 10 mW
  • Routing function
  • External antenna

The ZR-AIC-EM features to analogue inputs to detect a voltage direct-current signal in between 0 and 20 mA plus 2 other digital inputs. The digital inputs control up to 2 pulse counters. This device acquires the inputs and sends the data collected and generated to a compatible gateway at regular intervals. The ZR-AIC-EM is supplied continuously; therefore it can also act as a repeater or a “parent” device for battery powered sensors.
