The GE-Emerson IC670ALG230 Field Control Current Source Analog Input Module converts current levels to unscaled analog input data. Analog scaling is performed by the Bus Interface Unit, which provides the scaled data to the host. Software Range selections of 0 to 20mA and 4 to 20mA are configurable on a per-channel basis. The default range is 0 to 20mA. The default scaling for the module is:

  • Eng Lo = 0
  • Eng Hi = 20,000
  • Int Lo = 0
  • Int Hi = 20,000

The module includes 8 words (16 bytes) of input data. A Bus Interface Unit is required to provide this input data to the host and/or local processor. 

The 250 ohm resistor converts input current to a voltage with respect to common. The input R-C filters high-frequency noise, while the op-amp buffers the signal to the analog/digital converter. All eight +24VDC Out terminals are common to each other. The chassis ground goes to the I/O Terminal Block ground terminal.
