INFO
Remember to install the freewheeling diode (
). This diode prevents a sudden voltage spike across the inductive
load when the voltage source is removed.
6.7.3 Load sharing wiring
The active (P) and reactive (Q) load sharing terminals on the GAM3.1 module are reserved for future use for analogue load sharing.
6.7.4 Analogue current or voltage outputs wiring
The diagram below shows the connection of an external controller to the DEIF controller's analogue current or voltage output. The
I/O configuration determines whether the output is current or voltage.
CAUTION
These outputs are active outputs. Do not connect an external power supply to these terminals. Connecting an external
power supply may damage the terminals.
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.
Using an analogue output with a switchboard instrument
The analogue output can be connected directly to a 4 to 20 mA switchboard instrument. This is shown below.
INFO
DEIF recommends using switchboard instruments from the DEIF DQ moving coil instrument series. See http://
www.deif.com for more information.
