Wireless I/O Unidirectional Transmitter/Receiver Units – Introduction

Wireless Input/Output (I/O)

Wireless I/O connects directly to analog, discrete and pulse transducer signals. The signals are transmitted by radio and either

re-created as output signals, or output via serial link or field-bus.

Weidmuller Wireless I/O units have the ability to form sophisticated peer-to-peer networks, with event-reporting messaging

to optimize wireless density. Weidmuller products are designed for high reliability operation on open license-free radio bands.

WI-I/O 9-L Unidirectional Transmitter/Receiver Units

• Frequency hopping spread spectrum 902-928 MHz 1W license-free USA/Canada

• Configurable sub-bands license-free Mexico, South America, Australia/NZ, Hong Kong

The Unidirectional Wireless I/O range of products is suitable for connecting to a single sensor or group of sensors and provides an

economical solution for remote monitoring systems. The Unidirectional L products can also be used in more complex networks as

signal transmitters or receivers

Features

Matched transmitter/receiver pair of modules, or individual transmitter and receiver units

• Peer-to-peer communications. Exception reporting. Reliable self-checking messages. Highly secure data encryption.

• Multi-hop repeater functions - up to 5 intermediate units can be configured in any input-output link

• Factory configured as a matched Transmitter/Receiver pair or user-configurable with E-Series Windows configuration program

Transmitter unit

• Input-only transmitter unit - two digital/pulse inputs, one analog input and one thermocouple mV input

• Transmits to Receiver unit as a matched pair where the input signals are re-created as output signals,

or can transmit to a Multi-I/O or Gateway unit

• Class 1 Div 2 hazardous areas approval (USA/Canada)

• Up to 3000 wireless units per network

• External inputs plus internally calculated values - analog setpoint status, pulse count, power supply voltage

• Thermocouple input –100 to +100mV with cold-junction compensation and linearization for J, K or T-type

• Setpoints status generated by comparing analog input to high and low setpoints

• Digital inputs can also be used as pulse count inputs

• Power supply 9 – 30VDC, measured and available as a transmitted variable

• 24VDC analog loop supply internally provided

• RS232 Configuration and diagnostics port

Receiver unit

• Output-only receiver unit - three digital contact outputs and one analog output

• Receives radio commands from Transmitter unit as a matched pair where the input signals are re-created as output signals,

or can receive commands from a Multi-I/O or Gateway unit

• Class 1 Div 2 hazardous areas approval (USA/Canada)

• Up to 3000 wireless units per network

• Power supply 9 – 30VDC; 24VDC analog loop supply internally provided

• Communications failure indication and configurable output

• Outputs can be configured as retained or reset (fail-safe) on communications failure

• LED indication of radio signal strength

• RS232 Configuration and diagnostics port
