About the Product

By connecting the Control Board to an AirHMI display you can manage your inputs (analog and digital) and carry out control tasks easily with the on-board relays.

It has 8 relays rated 24V 7A. The relays work as dry contacts for switching.

Reads ADC values through 4 analog inputs.

Handles on/off signals through 4 digital inputs.

It works with command sets over UART.

There is an indicator LED for each relay.

With the optional RS485 option, up to 4 boards can be addressed and connected side by side, expanding to 32 relays, 16 analog and 16 digital inputs.

The DIN rail enclosure option makes mounting in panels and similar locations easy.

It is widely used in various industrial and robotics projects.
