These modules can be used with any system that communicates using Modbus serial RTU protocol. Common features to all A Series modules include:

Robust, yet low cost option for low I/O count or distributed I/O systems
Detachable terminal block for easy module replacement without re-wiring
Compatible with any Modbus RTU serial master device via RS-485, 2-wire
Small size (72x123x35mm)
DIN-rail or wall mount, multiple modules can stack atop each other to minimize space requirements
High noise immunity
Operating temperature -25~75°C
10~30 VDC power input, low power consumption
