ioPro™ DAIO
AI, AO, DI, DO, and RTD Modbus IO Module
Flexible Modbus-RTU IO Module
2 x AI, 1 x AO, 4 x DI, 2 x DO, and 2 x RTD
Features of the 8AI, 8AO, 8DIO, and 6RTD in 1 Unit
LED Status Indication on Power and RX / TX
Operating Temperature: -40˚ to 80˚C
1500V RMS Isolation
Fully Compatible with the ioPak WDL Radio
The ioPro DAIO module is a multi-purpose combination of analog and digital inputs and outputs. The module can
accommodate either 2 or 3 wire RTD sensors, current (0-20mA) or voltage (0-10V) inputs, current (0-20mA) or
voltage (0-10V) output, and digital inputs and outputs.
RTD Inputs (See 6RTD): Two linearized channels with 0.1° degree resolution and downscale burnout
AI Inputs (See 8AI): Two channels jumper selectable 0 to 20mA or 0 to 10V with 12 or 16 bit resolution
AO Outputs (See 8AO): One 12 bit channel jumper selectable 0 to 20mA or 0 to 10V
DI Inputs (See 8DIO): Four 24VDC inputs with configurable 32 bit counters
DO Outputs (See 8DIO): Two 24VDC outputs with configurable watchdog timer
There is no channel to channel isolation so isolated RTDs are required, and care should be taken when connecting
signal from multiple devices with possibly different ground potentials.
