About A Series I/O
A Series I/O modules with Modbus capability 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
- Mount onto DIN rail or wall, multiple modules can stack atop each other to minimize space requirements
- Small size (60x110x27mm)
- High noise immunity, 2500 VRMS
- 10~30 VDC power input, low power consumption
