Chapter 15 – Installation
Before making the electrical connection, make sure the signal is applied in accordance with the technical
specifications of the equipment. For information about DC transducer inputs specifications, see Section 3.4
of the Specifications Chapter 17.

5.11 ANALOG DC TRANSDUCER INPUTS ± 20 MA
The RA331, RA332, and RA333 modules have up to 8, 16, or 8 analog inputs, respectively, which can be
configured for measurement of currents of DC transducers of -20 mA to 20 mA. All channels are identified of
101 to 108 for the RA331 and RA333, and 101 to 116 for the RA332.
Each analog input has three terminals: positive voltage, positive current and negative terminal which are
used for the current and for the voltage, as shown in Figure 124.
To define if the driver will measure current of a DC transducer it is necessary to select an internal jumper in
the module.
Figure 124: Analog Input Terminals
In order to configure the analog input to measure currents signals of DC transducers, remove all connectors
and cables which are connected to the module and remove the back panel of the RA331, RA332 or RA333,
removing the 12 screws of the panel and the screw of the protective grounding, as shown in Figure 125.
