Brainboxes ED Series Industrial Ethernet to IO Devices - Brainboxes ED-549, Ideal for all kinds of industry standard sensors and transducers. The ED-549 has 8 analogue Inputs + RS485 expansion port. It is suitable for high-precision measurements of voltages and currents. Most parameters in the real world are measured using sensors with analogue output sensors and Brainboxes ED-549 takes these real world signals and turns them into data on your network.As well as the popular 0 to 10V and 4 to 20mA input devices, there is now a Programmable Gain Amplifier (PGA) allowing 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
