Warranty:	2 years

The 4R-D7 module allows you to control 4 relays using the Modbus RTK protocolCommunication with the device can be done via RS-485 or UART TTL interface

In addition, the device has 4 control inputs protected by optocouplers (input voltage range: 3.3 V ... 30 V)The voltage from the control inputs is not the voltage directly supplying the relay coil

Remark! The control interface is selected using jumpers located on the boardIt is not possible to control the outputs using both communication paths at the same time

Despite our best efforts, we cannot guarantee that the published technical data and photos do not contain inaccuracies or errors, which, however, cannot be a basis for claims.
