DESCRIPTION
This module is ideally suited to controlling multiple larger voltages within a project. This relay module which can be used to activate up to 250V AC and 30V DC. This allows you to build in device control, operating remote lights or triggering systems when the module is supplied with a signal. This signal can come from a range of sources including most standard microcontrollers.
The module is controlled using the common communication protocol Modbus. This can be communicated by either UART or 485 serial.
The pins are suited to standard sockets with a pin pitch of 2.54mm. The relay has a set of screw terminals with labels to indicate the standard state relationship between them.
Please do not hesitate to contact us if you require further information regarding the module's operation.
