The FreeWave Technologies IO Expansion Module offers a scalable solution to meet the demands
of your automation requirements. The IO Expansion Module may either be stacked on an
applicable IO radio or can serve as expandable remote IO modules through a serial connection.
Regardless of the configuration, up to 16 modules may be stacked on the radio or base module.
The IO Expansion Module is Class 1 Division 2 UL approved and adds significant flexibility to an
existing Modbus IO network.
- Base IO Expansion Module offers 4 AIs, 2 Isolated DIs, 2 Isolated DOs and 4 Universal Pins which can be configured as AIs, AOs, DIs, or DOs.
- Affordable - Low installation and long -term maintenance costs.
- Low Latency - Less than one second signal delay.
- High Accuracy - FGRIO System analog signal fidelity is factory calibrated and drift with time and temperature is much less than that of transducers.
- Short Range/Low Power - Suitable for solar powered installations.
- Error-Free Communications - 32 bit CRC with automatic retransmission.
- Industrial Grade Specifications -Temperature range from –40 degrees C to +75 degrees C.
- Can function either with a radio or as a standalone module providing additional IO capability for 3rd party devices.
- 16 or 20 bit resolution on AIs.
- Fail Safe - Allows you to set Analog and Digital Outputs to a safe state in the event of a communication failure.
- Point to Multipoint Modbus Communications.
- Modular design, expandable up to 16 modules.
- UL Approved Class 1, Division 2 - Groups A, B, C, & D
- Operating Temperature Range -40 degrees C to +75 degrees C. Every radio 100% factory tested over this range.
- Dimensions Board Level:7 1/8 inch Hx 3 1/8 W x 1 inch D
- Weight: 0.35 lbs
- Humidity 0 to 95% non-condensing
