MODCELL Multiloop Processor
PRODUCT DESCRIPTION
1.4.2 2002A Current Input Module
The current input module is identical to the voltage input module except for the addition of
a 250 ohm resistor across the two input leads. This allows the standard 4-20 mA DC
input range to be accommodated by the module. This module uses the Voltage/Current
Input Module (VCIM) Block for configuration of input parameters.

1.4.3 2012A Current Input Module (with 2-wire transmitter power)
This module is designed specifically for two-wire transmitters and provides the necessary
24 V DC current limited supply to power the transmitter. An internal current sense resistor
converts the current to a voltage for application to the A/D converter. All other features
are the same as the voltage input module. This module uses the Voltage/Current Input
Module (VCIM) Block for configuration of input parameters.
