input/output and power supply board

Note: Connecting the terminal board is always described on the inner label placed
on the meter rear lid or the cover metal sheet of the power source.

Evaluation unit terminal board wiring:

Terminals No. 1, 2

current output 4÷20 mA

Terminals No. 3, 4

impulse output OUT IMP

Terminals No. 5, 6

RS485 communication

Terminals No. 7, 8

output 2

Terminals No. 9, 10 reset Total V register (resettable counter) by external

button

Terminals No.11, 12 output voltage 16 V/100 mA (power supply for changing

to active current and impulse outputs)

Terminals L, N, PE

mains voltage 230 VAC (standard), available also in 24
VAC/VDC version (Install as an independent supply cir-
cuit with its own protection 0.5÷1 A)

Under no circumstances should the cabling form loops or similar.
A separate cable should always be used for the power supply.
