3.4.1 Pulse outputs connection
The meter has ТМ1 and ТМ2 pulse outputs. The outputs can be used as the main output transmitter with
parameters in accordance with IEC 62052-11:2003, IEC 62053-21:2003 (IEC 62053-22:2003). The outputs
are implemented on transistors with an «open» collector and are intended for switching DC voltage. Nominal supply
voltage (10±2) V, maximum allowable value is 24 V.
The value of the switched nominal current is (10±1) mA, the maximum allowable value is 30 mA. By
default, ТМ1 generates pulses, proportional to the consumed and delivered active energy values (A
i
+A
e
), ТМ2
generates pulses, proportional to the consumed and delivered reactive energy values (R
i
+R
e
). The outputs can be
reconfigured to generate pulses proportional to the individual type of the metered energy or as a relay (for details,
see САНТ.411152.107-05.1 РП).
To ensure the functioning of pulse outputs, it is necessary to supply DC voltage according to the scheme shown
in Figure 3.3.
