Product Description

Ideal for all kinds of industry standard sensors and transducers. The ED-549 has 8 Analogue Inputs + RS485 Gateway. It is suitable for high-precision measurements of voltages and currents. Most parameters in the real world are measured using sensors generating analogue outputs. Brainboxes ED-549 takes these real world signals and turns them into data on your network. As well as the popular 0-10V and 4-20mA input devices, the inbuilt Programmable Gain Amplifier (PGA) allows full scale signals as small as ±75mV to be resolved to 12 bit accuracy across 8 analogue inputs. Each channel is individually configurable for voltage or current input with its own programmable gain.

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 can 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. 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..
