The ED-549 is an 8 analog input Ethernet device with RS-485 gateway. It is suitable for high-precision measurements of voltages and currents. In addition to the popular 0 to 10 V and 4 to 20 mA input devices, there is now a programmable gain amplifier (PGA) to resolve full-scale signals as small as ±75 mV with 12-bit precision on 8 analog inputs.
