20 mA Passive Current Loop Interface
The DP1200 only supports passive type current loop connections. The wires of the
external cable must be connected to the internal socket pins as indicated in Figure
16:
Pin Name Function
25 C.L. IN- Current loop input -
24 C.L. IN+ Current loop input +
19, 22 C.L. OUT- Current loop output -
18, 21 C.L. OUT+ Current loop
For the 20 mA current loop interface, a ferrite (type Stewart 28A2029-0A0) must be
applied on the user interface side of the cable to reduce electrical noise. Also the
shield must be referenced to GND at both ends.
