The high density, four- and eight-channel modules offer twice the
number of channels per module in the same standard expansion module
case size. The EM231 series eight-channel analog input module supports industry
standard unipolar 0-10VDC, 0-5VDC, 0-20mA and bi-polar +/- 5VDC,
+/-2.5VDC input signals. The EM232 series four-channel analog output
module supports both 0-10VDC and 0-20mA output signals. The EM231 TC eight-channel thermocouple temperature input module
supports seven different thermocouple sensor types and +/-80mv input
signals, enabling it to perform in a variety of temperature control
applications. The EM231 RTD new four-channel RTD temperature input
module supports eight different RTD sensor types and 150-ohm, 300-ohm,
and 600-ohm resistance inputs.
