F3--04DAS 4-Channel Isolated Analog Output
The F3--04DAS module has a removable connector to make wiring easier. Simply
squeeze the top and bottom tabs and gently pull the connector from the module.

Note1: Shields should be connected to the respective channel’s
-- V terminal of the module.
Note 2: Each isolated output channel may have either a voltage or
current load, but not both
Note 3: An external 0.31 Amp fast-acting fuse in series with the isolated
+I terminal (+15VDC) is recommended to protect against accidental
shorts to the --V terminal (15VDC common)
Note 4: Do not attempt to source more than 20mA from any one of the
four is15VDC power supplies

Internal wiring for CH2 & 3 is
similar to wiring shown above
See note
Internal Module Wiring
You may occasionally encounter transmitters that have a very unusual signal range.
Since each channel is isolated, you can “daisy chain” the channels to provide output
voltage signals that are outside of the normal operating range. For example, you
could connect the first two channels to provide a voltage output from 0 to 20 VDC.
