Ethernet to 4 Relays and 8 Digital Inputs + RS485 Gateway

  • 4 Form A Relays, 8 Digital Inputs and an RS485 Gateway Port
  • Easy-wire: Colour coded and numbered removable terminal blocks
  • Factory floor process control and automation, Integrated DIN rail mount
  • Supports simple ASCII or industry standard Modbus TCP
  • -30°C to +80°C Temperature range
  • Software APIs for Visual Basic, C# and more

Ethernet to DIO device: 8 non-isolated digital input channels and 4 digital Type A Relay Outputs. Powerful ARM 80 MHz, 32 Bit CPU. Offers robust and intelligent 'control side' devices that provide the interface to systems on the 24V factory floor environment, commonly referred to as 'process side'.

The device can be controlled over TCP/IP using the Modbus TCP protocol or simple ASCII commands. It behaves as a web relay controlled over ethernet. Additionally Brainboxes supply a suite of APIs and sample code to communicate with the device using Microsoft .NET framework Visual Basic, C#, C++, Java, Javascript, PHP and more. The device and be configured and secured from a web browser. The device can be installed as a COM Port on a Windows PC to give complete backwards compatibility essential for legacy applications.

The ED product range is designed for harsh environments. The digital output port line are implemented as protected output circuits, providing current overload and short circuit protection, voltage surge, overload and open circuit protection and over temperature protection to allow the widest possible usage and range of devices.

The outputs are good for driving hot and cold resistive loads, capacitive loads and inductive loads and are especially suited for loads with high inrush currents such as cold bulbs/lamps and motors. Typical applications are control and switching of AC and DC motors, Fans, relay drivers, pumps, Voltage Regulators and Battery Chargers, LEDs and Bulbs, Air Conditioning, Heaters and Solenoids.
