Signal Wiring
As discussed on the previous page, a signal wiring diagram and terminal location for any device (e.g. SCM, Flow Input, Analog
Output) can be accessed by going to the device menu
(Menu>[Device]>Options) and scrolling down to “Connections”
(
see
examples at bottom right). Note: Wiring terminals cannot accept wires larger than 18 AWG.
The interconnect wiring between the HydroACT analyzer and DT4 sensor is shown below and under
Menu>SCM1.x>Options>Connections. Use 18 AWG, 4 conductor, shielded cable, max 1000 ft.
Terminal location & wiring for the analog output wiring is shown under Menu > xxx Out 1.x > Options >
Connections.
Terminal location & wiring for optional Flow 4-20 mA Input wiring is shown under Menu > Flow Input 1.x
> Connections.
Terminal location & wiring for optional Relays are shown under Menu > Relay x.x >Options >Connections.
Output Signal and Scaling Information
The Streaming Current 4-20 mA Output is typically mapped to Analog Output 1.8 and scaled -500 to +500.
The Signal Health 4-20 mA Output is typically mapped to Analog Output 1.7 and scaled 0 to 100%
The Optional PID 4-20 mA Output is typically mapped to Optional Analog Output 1.6 and scaled 0 to
100%
