A.3. Convert Current Input Channels to Voltage Input Channels on Expansion Card
When the RIM-1000 optional 12 channel analog input card is delivered, its channels are configured for current inputs (4-20mA).
Some sensors, however, may require voltage input channels (0-5V or 0-10V). The customer may manually reconfigure any or all
current input channels as voltage input channels if necessary.
The headers on the expansion card are labeled P1 through P12. Each number corresponds with a channel (e.g., P1 corresponds
with channel 1, while P10 with channel 10.) Each header has two parallel columns of five pins. Some pins are connected with
jumpers. Changing these header settings converts a current channel to a voltage channel, and vice versa.
To configure a header as a current channel (4-20mA), connect pins 1 and 3 with one jumper. Connect pins 2 and 4 with another
jumper. Connect pins 7 and 8 with a third jumper.
Figure A.8 Expansion Card Current Channel (4-20mA) Configuration
Note: Expansion cards are shipped from the factory with all headers configured as current channels.
To configure a header as a voltage channel (0-5V or 0-10V), connect pins 3 and 5 with one jumper. Connect pins 4 and 6 with
another jumper. Connect pins 9 and 10 with a third jumper.
