RTD/mA card variants

The available variants of RTD cards are 6RTD/2mA and 2RTD/1mA. The features are
similar in both cards.
6RTD/2mA card
This card accepts two milliampere inputs and six inputs from the RTD sensors. The inputs
1 and 2 are used for current measurement, whereas inputs from 3 to 8 are used for
resistance type of measurements.
RTD/mA input connection
Resistance and temperature sensors can be connected to the 6RTD/2mA board with 3-
wire and 2-wire connections.
