ATTENTION
Transmission error and material damage due to
electrical malfunction.
With a cable length of more than 30 m, there is an
increased probability of transmission errors and dam-
age to the device due to atmospheric discharge!
Use shielded cables for the connections to the digi-
tal inputs and outputs!
INFORMATION
Details on measurement displays for the digital input
module and the digital inputs can be found in Sect. “9.
Module-relevant measuring displays (800-DI14 module
only)” on p. 32.
Functions for the digital inputs can be configured
easily and clearly in the GridVis ® software (see www.
janitza.de).

5.2 Startup procedure/initialization
Modules started on a basic device (e.g. current
measuring modules or digital input modules) trigger
a blink interval of the LEDs. The blink interval of the
LEDs and the meaning can be found in Sect. 5.4.3
on p. 27.

5.1 Digital inputs
The digital input module 800-DI14 extends the
functional range of the UMG 801 basic device by an
additional 14 digital inputs.
When connected to the UMG 801 basic device, the
digital inputs of your 800-DI14 module receive infor-
mation from other devices with digital outputs (pulse
generators).
The digital inputs detect an input signal at a voltage
of at least 18 V and at most 28 V DC (typically at
4 mA) or a current of at least 0.5 mA and at most
6 mA.
For voltages from 0 to 5 V and currents less than
0.5 mA there is no input signal.
