Ethernet to digital I/O module for industrial automation, now in distribution

Enables process engineers to communicate in any environment, from any location; the ED-588 industrial specification input/output (I/O) module from Brainboxes simplifies remote monitoring and control.

RS Components is stocking the ED-588 remote Ethernet to digital I/O (DIO) device featuring eight non-isolated digital input channels and eight digital output channels, with an integral DIN rail mount and shape (22.6mm wide) that uses minimal space. The module contains an ARM 80 MHz 32-bit CPU, with control capability to enable system interface on the factory floor. The ED-588 has a gateway RS485 serial port that can be used to connect to industry-standard NuDAM, eDAM and ADAM modules – a staple of process control systems.

A wide range redundant dual power input (+5VDC to +30VDC) accommodates variation in the +24VDC factory floor supply and allows alternative power sources. A second power supply can be fitted as a back-up to prevent down time should one power source fail. Power can also be sourced using 5V power from any computer USB port for configuration away from the installation site. A watchdog feature allows independent known good states to be set for power up, comms link watchdog, and hardware watchdog. Programmable time range allows full control. Removable, individually numbered colour coded blocks and ports ease installation and simplify wiring.

Capable of driving high current and high voltage loads, the ED-588 is suitable for inductive, capacitive and resistive loads such as CNC machines, stepper motors, heating ventilation and air conditioning. Operating at an extended temperature range of between -30ºC and +80ºC enables the device to cope with extreme changes of temperature in harsh environments. The CPU temperature and power supply status can be monitored via the web interface or programmatically through ASCII commands.

The ED-588 is implemented using a Microsoft Windows COM port driver that is compatible with industry standard software packages such as LabView, MATLAB, and Agilent VEE, and supports a range of Application Programming Interfaces (APIs) including Microsoft .NET - C#, Visual Basic, C++ and JavaScript. Drivers are available for the latest operating systems including Windows 8, and the user interface
