INFO
DEIF recommends that a 2 A slow blow fuse is used for F1 and F2, and that the diodes are rated 50 V or higher.
6.8.4 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.
Using an analogue output with an external instrument
The analogue output can be connected directly to a 4 to 20 mA external instrument, as shown below.
