1 AC-LINE Measure AC utility power, 90 to 264 VAC. This
input is isolated from all other inputs.
Line Voltage
2 AC-NEU
3 INVIN
Measures a fl oating AC sources like an inverter, 90
to 135 VAC. INV IN (GND) is common to all GND
and RTN and -PWR IN.
Inverter Voltage
4 INVIN(GND)*
5 Is 2
Measures DC voltages across a 100mV/100A
current shunt. Is1 and Is2 inputs may be
referenced to either (+) or (-) and/or RTN/GND. 60
volt max common mode and 100mV differential
input
Shunt Current
6 Is 1
7 −DCVs Measures a negative voltage with reference to
GND/RTN. -30 to -60 VDC.***
- Volts DC 3
8 GND*
9 A3
Measures a relay or switch contact closure. Short
across inputs will indicate CLOSE. Open circuit is
OPEN.
Contact 3
10 A3RTN*
11 A2
Measures a relay or switch contact closure. Short
across inputs will indicate CLOSE. Open circuit is
OPEN.
Contact 2
12 A2RTN*
13 A1
Measures a relay or switch contact closure. Short
across inputs will indicate CLOSE. Open circuit is
OPEN.
Contact 1
14 A1RTN*
15 +V3IN Measures a postive DC voltage, 0 to 40 volts with
reference to GND/RTN.
Volts DC 2
16 GND*
17 +V2IN Measures a postive DC voltage, 0 to 40 volts with
reference to GND/RTN.
Volts DC 1
18 GND*
19 −PWRIN*
SPM-200 input power, 9 to 60 VDC, maybe
powered directly from “Negative Ground” system
only.**
(N/A)
20 +PWRIN
* CAUTION: Common to all input grounds and returns.
** Neg. DCV is not compatible with input voltages that are positive with respect to pin 8 GROUND. CAUTION:
If you intend to power from -48 VDC AND monitor -48 VDC, input power must come from an isolated DC con-
verter. If you need one, we will provide it free of charge. Contact NEWMAR: 800-854-3906 or E-mail:
