Product description
32-channel relay module for DIN rail mounting. Controlled via Modbus RTU over RS485. The module is an industrial, serially controlled relay interface intended for applications such as building automation or industrial automation. It is controlled via RS485 using the Modbus RTU protocol. The module is powered by 7-36 VDC. Opto-isolation between the relays and the digital interfaces provides good protection. The relays are of high quality and can handle loads up to 10 A at 250 VAC or 30 VDC. The module supports advanced functions such as temporary activation (flash-on/flash-off) via command arguments.
