Programmable 8 Channel 16 Amp Relay Module with Ethernet (dS378)

The "dS378" allows you to control 8, 16 Amp relays over an Ethernet connection using a built in web page or via simple TCP/IP based commands. 7 flexible I/O channels allow you to capture sensor readings and control other devices. The module can be programmed to respond to the inputs, send and receive commands over TCP/IP and has a customisable web page interface.

The dS378 provides 8 relay outputs with a current rating of up to 16Amp each. The module can be programmed using dScript (see below) enabling you to make the board respond to inputs and send/receive commands from other devices on the network.

The module is power from a 12vdc supply which can be regulated or unregulated (not included).


  • Create a custom webpage - Add your own logo, buttons and functionality

  • Control using a mobile phone

  • Add a tcp server - Respond to incoming tcp requests with your own functions

  • Include a tcp client - Send packets of tcp data to other devices using your own protocol

  • Serial ports - 2 (1 x TTL serial and 1 x RS485)

  • Relays - 8 with up to 16Amp @24vdc or 250vac, screw Terminals for N/O N/C and Common contacts

  • Digital I/O / Analogue inputs - 7 flexible channels with your choice of 10 bit analogue input or digital i/o.

  • Communication - USB for development, RJ45 ethernet for normal access

  • Power - 12V DC jack 2.1mm (adaptor sold separately)

  • Current requirements for the dS boards is 150mA + 40mA for each relay that is on.
