one-way link is required
• Powerful 900MHz frequency-hopping
1W transmitter
• Factory configured as matched pair,
or user-configurable
• Use with Wireless I/O and Wireless Gateway
family– up to 3000 units per network
WI-I/O 9-L-T Transmitter Unit
• Two digital/pulse inputs, one analog input
(4-20mA, 0-5V), and one thermocouple mV input
• LED indication of radio signal strength
WI-I/O 9-L-R Receiver Unit
• Three digital contact outputs and one analog
output (4-20mA)
• LED indication of radio signal strength

Transmitter Inputs
Digital/Pulse Input, two inputs, suitable for voltage free contacts / NPN, or voltage input 0-1 VDC on / >3 VDC off, pulse input max rate 10 Hz, 50 msec on time,
pulse counted as 16 bit register, 6mA wetting current.
Analog input, 0-20 mA span and zero configurable (default 4-20mA), “floating”
differential input, resolution 16 bit, accuracy < 0.1 %
Thermocouple input, -20mV to +100mV, J, K or T type linearization with on-board
cold-junction compensation, accuracy better than 1degC, 100kohm input impedance, +10 V common mode voltage.
Setpoint Status, setpoint status sets (on) when analog value < low setpoint and
resets (off) when analog value > high setpoint, status transmitted as per digital
input, setpoint values are settable via front-panel rotary switch or configuration
System OK output
Configuration and Diagnostics
Factory configuration transmitter/receiver
matched pair. User configuration via serial
port. Unidirectional units can be configured to
network with Multi-I/O and Gateway units.
Diagnostics features – read input values, write
output values, radio signal strength, monitor
communication messages.
