ENERGYMID 18 | 71

Interfaces

The energy meters are equipped with two pulse outputs or one bus output as a standard feature.

Pulse output:

Model and feature-dependent, as well as optional:

 S0 standard, 1000 pls/kWh (V1) /

 S0 Programmable, 1… 1000 pls/kWh Secondary,

(V2 at EM2281 / EM2289) /

 S0 Programmable, 1… 50000 pls/kWh Secondary,

(V2 at EM2381 / EM2387 / EM2389) /

 Switching output up to 230 V, 1000 pls/kWh (V3)/

 Switching output up to 230 V, programmable, 1 … 1000 pls/kWh

(V4 with EM2281 / EM2289) /

 Switching output up to 230 V, programmable, 1 … 50,000 pls/

kWh (V4 with EM2381 / EM2387 / EM2389) /

 S0 130 ms, 100 pulses/kWh

(V7 at EM2281 / EM2289) /

 S0 130 ms,100 pls/kWh, in combination with Q9 depending on

CT × VT

(V7 at EM2381 / EM2387 / EM2389) /

 S0 130 ms,1000 pls/kWh (V8) /

 Customer-specific S0 (V9)

See  "Pulse Outputs" 19 for further information.

Bus connection:

Optional:

 LON (W1) /

 M-Bus (W2) /

 Modbus RTU (W7) /

 TCP/IP (BACnet / Modbus / TCP / HTTP) (W4) /

 Wireless interface LPWAN supporting the LoRaWAN

protocol

(W8)

See  "Bus Interfaces" 20 for further information.

Antenna connection:

Optional:

SMA at LPWAN (W8)

See  "Bus Interfaces" 20 for further information.

Tariff interface:

4 tariffs (hardware controlled) and 4 additional tariffs with bus feature

W1 / W2 / W4 / W7

Power utility pulse:

a. The 4 additional tariffs via bus are not included in the scope of MID approval.

Transformer ratio

EM2381/ EM2387 and EM2389 only:

default: CT = VT = 1, main display for secondary (Q0)

Feature-dependent alternative: CT and VT programmable, auxiliary display for secondary, permit-

ted for billing purposes (Q1) / fixed CT and VT, main display for primary (Q9)
