- 3 Analogue Inputs (8 or 12-bit): Suitable for acquiring data from analogue sensors and transducers.
- Temperature Sensor Support: Direct measurement of process or ambient temperature.
- 16 Relay Outputs: Reliable switching of loads, motors, valves, and other high-power devices.
- 3 Analogue Voltage Outputs (0-10V, ±10V): Flexible generation of analogue signals for industrial equipment.
- 1 Analogue Current Output (4-20mA): Standard current loop output for industrial control applications.
- Onboard Pressure Sensor: Integrated pressure monitoring for process and automation systems.
- Buzzer and LED Indicators: Immediate visual and audible status feedback for diagnostics and operation.
- DIP Switches for Modbus Register Assignment: Straightforward configuration of Modbus addresses directly on the module.
- Reset Button: Quick system reset, also accessible via Modbus command.
- Wide Input Voltage Range: Operates from 18VDC to 34VDC, with low standby consumption (120mA @ 24VDC).
