Shield module for Arduino MEGA 2560

- 12-30V DC power supply
- 24x digital inputs – optically separated, max. input voltage 24V DC
- 12x relay outputs – galvanically separated, max. current 5A at 230V AC per 1 output
- 3x analog inputs – input voltage 0 - 10V against the AC terminal, resolution 1024 bits
- 4x PWM digital outputs – max 25 W / 1 output, max 24V DC, f = 490 Hz
1-wire communication – possibility to connect any 1wire devices - eg DS18B20
- I2C communication – reserved for possibility to connect eg access systems, RTC, contact indicator etc.
RS485 communication  – possibility of serial communication with a master systems (e.g. Loxone Modbus extension, other Arduino module...)
- Status LED diode – indication of operation
Reset button – restart of the module
- Switch DIP – for the address setup of the Modbus protocol – up to16 addresses
- Terminator – RS485 bus termination jumper
- Terminal blocks - also with counterparts
