Note 1
: When analog current signals are used, be sure to jumper the “V+” and “I+” terminals.
Note 2
: If electrical noise issues occur, connect FE to the grounding terminal.
Note 3
: Connect the
terminal on both the power supply and analog module to the system
earth ground.
Note 4
: If electrical noise at the input terminals is significant, connect the following capacitor:
0.1 ~ 0.47
