Deif PPM 300 - Pulse Width Modulation (PWM) Output Wiring; Analogue Current or Voltage Input Wiring

6.7.5 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.

INFO
The PWM output is galvanically connected to the first analogue output (terminals 12 and 13) on GAM3.1. This means that
wiring errors or noise on either output can affect the other output.
6.7.6 Analogue current or voltage input wiring
The I/O configuration determines whether the input is current or voltage.
CAUTION
Configure the terminals correctly (that is, for current or for voltage) before connecting the external transmitter.
Current input
The current input may be either active or passive.
The following diagram shows the connection of an active transducer.
