Sch02P, Sch72P, Sch96P, Sch120P

Sch02P, Sch72P, Sch96P, Sch120P meters are intended to measure and convert current and voltage in DC circuits into output unified DC signals and serial digital interface RS485, which allow using the meters in automated systems of various purposes.
The meters provide the possibility for programming with built-in buttons or through the interface: indication range, decimal point position; level of the controlled values of input signals (settings); change in brightness of digital indicators illumination; interface parameters.
Sch120P meets the requirements of PJSC ROSSETI and PJSC FGC UES, they are recommended for the use at facilities of JSC ROSSETI and PJSC FGC UES.

Sch72P – 72×72,
Sch96P – 96×96,
Sch120P – 120×120,

b – measurement range for the input signal with direct connection or transformation factor with connection through the outside shunt
mV: 60, 75, 100, 150, 200, 250, 500, 1000, 2000
