S0 Pulse input
Each input can also be used as an S0 pulse
input to DIN EN62053-31. An external auxil-
iary voltage of 20..28V DC and an external
1.5kOhm resistor each is required for this.

Installation
Digital inputs
The UMG507 has a total of 6 digital inputs
which can be connected to transducers. An
input signal is detected at a digital input if a
voltage of at least 10V and maximum 28V is
applied. A current of at least 1mA and maxi-
mum 6mA then flows.

main switching contacts S1 and S2 to the
digital inputs 5 and 6
