Project Description

TIR2 – ZigBee Modbus Relay Module Print datasheet

Sensor with input for NTC temperature probe, 2 digital inputs and 2 relay outputs
Main technical specifications
  • 2 digital inputs
  • 1 NTC probe input (probe not included)
  • 2 relay outputs
  • Sampling intervals and data transmission to the Gateway can be customised to increase battery life.
  • Customisable range of measurements for recording level alarm conditions: settings can be used by the supervisor to generate alarms and/or warnings (e.g. to check whether doors, windows, etc. are closed/open).
  • Routing functionality
  • External antenna for maximum efficiency
  • Building automation and industrial control systems
  • Energy monitoring and management

Devices for acquiring the status of two ON/OFF digital outputs and NTC temperature probe readings; 2 configurable relay outputs for controlling external third party devices. In a wireless network, these devices regularly transmit acquired data to a ZigBee Gateway and serve as radio signal repeaters for nearby sensors.

All digital input status changes are sent to the Gateway irrespectively of sampling time.
