Radio Telemetry (Wireless I/O)

More Information

105U and 505U telemetry units transmit signal values from transducers, switches or
sensors per radio. Inputs / outputs can be digital or analogue. Certain modules also
cater for pulse inputs/outputs for counting or frequency transmission.

  • Transmission triggered by change of input signal and after pre-configured time
  • Security encryption with system addressing to avoid cross-talk
  • Dynamic error-checking
  • “Listen before transmit” operation
  • License-free radio band: 405-490MHz (100mW), 869MHz (500mW)
  • Long distance: up to 50km per hop (5W, licensed, line-of-sight)
The I/O Modules from Elpo can be used to sense remote digital, analogue and pulse I/O signals.

Pulse and digital I/O are same. The 105-4 has 4 fixed inputs and 4 fixed outputs and 12 which may be either input or output
U= radio transceiver, S= serial 485 expansion module 
105U products provide multiple I/O channels with transceiver two-way communication.
Different I/O versions are available and inputs on one version can be linked to outputs on another version
  • Multiple digital, analog and pulse I/O
  • I/O expansion with 105S unit
  • Analog setpoint status with high/low setpoints
  • Pulse count (totalizing) and pulse rate values calculated
  • Failsafe outputs, configurable
  • Unit can act as repeater for other unit

505U is a transmit-only product with ultra-low energy consumption, suitable for powering from
a battery pack. It offers an economic solution for remote monitoring of process signals.

  • Two digital inputs
  • One analog input
  • Power-saving “sleep mode”
  • Low-battery alarm
  • Compatible with 105U
