Powered Pulse Counter

  • 2 pulse counter inputs S0 compatible
  • 2 Optical Pulses
  • 2 thermal resistor inputs
  • Sampling and transmission rates are configurable
  • 12-24 Vdc/Vac supply
  • Routing function
  • External antenna
  • RF power amplifier: 10 mW

The ZR-CI-ZB-EM is a powered ZigBee device, capable to count pulses emitted from flow rate meters gas, water and electricity also is able to measure the temperature from both the 2 on board NTC inputs. Pulse counters and temperature samples are sent at regular intervals to a gateway of 4-noks products family. Moreover, if temperature sensors are installed into an hydraulic circuit in the inlet and outlet pipes this device can send the difference between them.
