Installation
Digital inputs
The Energy Meter 610-PB and Energy Meter 610 have 4 digital
inputs, each of which can have a signal transducer connected.
On a digital input an input signal is detected if a voltage of at least
10 V and maximum 28 V is applied and where a current of at least
1 mA and maximum 6 mA ows at the same time. Wiring longer
than 30 m must be screened.
Note the correct polarity of the supply voltage!

S0 pulse input
You can connect an S0 pulse transducer per DIN EN 62053-31 to
any digital input.
This requires an auxiliary voltage with an output voltage in the
range 20 to 28 V DC and a resistor of 1.5 kOhm.
