INFO
DEIF recommends using instruments from the DEIF DQ moving coil instrument series. See http://www.deif.com for more
information.
6.8.5 Pulse width modulation (PWM) output wiring
Pulse width modulation (PWM) output is normally used to control a governor. The PWM could also be used as an input for another
controller, as shown in the diagram below.
6.8.6 Digital inputs wiring
The digital inputs are bi-directional inputs. This means that wiring to the input and common terminals may be swapped around
without affecting their operation.
However, all the digital inputs in a group share a common terminal. The digital input common for a module may be either low
(connected to 0 V), or high (connected to 12 or 24 V). If the common is low, all the digital input signals connected to the group must
be high (connected to 12 or 24 V). Similarly, if the common is high, all the digital input signals connected to the group must be low
(connected to 0 V).
The digital input common does not act as the common for any of the other terminals on the same hardware module. The digital input
common is also not affected by the digital input commons on other hardware modules.
The digital inputs are designed for a nominal voltage of 12 to 24 V DC.
