Analog
Input 2
4-20mA (default) or 0-5VDC.
0-5VDC is activated by removing JP2 (inside case).
4-20mA loop resistance = 240 Ohms.
AIN2- is connected to DC Common (GND).
Caution: AIN2+ should NEVER be connected to a voltage greater than 5VDC
above the DC common.
(See Recommended Wiring Diagram later in this section.)
Non-Isolated, Fused.
If isolation is desired, an external analog-to-analog isolation module may be
used. (eg. Dataforth Sensorlex
®
8B series or DSCA series modules.)
