INPUT / OUTPUT MODULE SPECIFICATIONS

The IO module provides RTD inputs; analog inputs and outputs; and digital inputs and outputs. The IO module will communicate to the Control Module using a serial CANBus interface. Multiple IO modules can be dropped on the CANBus interface to allow IO expansion when required. Identical IO modules will be used for IO expansion.

Environmental:

• Operating temperature range:      32°F – 122°F       (0 – 50°C) minimum rage
• Storage temperature range:         -10°F to 140°F    (-23 – 60°C) minimum range
