Note: it is possible to connect the outer circuits according to the designation of connector contacts to the terminals “for screw” using a cord of up to 4 mm2 in cross-section, multi-core wires of up to 2.5 mm2. When connecting supply DC voltage of 120...265 V at supply voltage of 220 VU to power contacts “L”, “N”, any polarity is possible. * Maximum input signal overload (from the rated value of the measurement range) 130% (2 hours). |

Order form
Sch а – b – c – d – е – f – g – h
Sch – meter type (by the Overall dimension, mm):
Sch02P – 96×48,
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
V: 1, 2, 5, 10, 2…10, 20, 50, 100, 150, 200, 250, 500, 750
mA: 2, 5, 10, 20, 4…20, 50, 100, 200, 500, 1000
А: 1, 2
Note: if the indication range differs from the measurement range the input signal and from the shunt conversion factor, give additionally the ordered indication range in the note to the order formula.
c – reference designation of supply voltage:
5 VN, 12 VN, 24 VN, 220 VU, 230 V
d – availability of interfaces RS485:
1RS – one interface,
2RS – two interfaces,
х – with the absence of parameter (for Sch120P only)
e – reference designation of analogue and digital outputs:
02 – two digital outputs without analogue output,
11 – one analogue and one digital output,
12 – one analogue and two digital outputs,
20 – two analogue outputs without digital ones,
22 – two analogue and two digital outputs,
х – without analogue and digital outputs
Note: the reference designation of analogue output is specified after figures in brackets: А = 0...5 mA, В = 4...20 mA, С = 0...20 mA,
АР = 0…2.5…5 mA, ВР = 4…12…20 mA, СР = 0…10…20 mA,
when ordering two analogue outputs, specify it separated by a comma.
f – indicators colour:
R – red, G – green, Y – yellow
g – accuracy class: 0.1 or 0.2
h – special design:
ОМ2 – meters for marine application,
А – for operation at NPP (safety class 4), do not specify in other cases.
