5.2.3. External interface with a wiring distance of 0.5 up to 300m
The maximum wiring distance of the external interface is 300 meters. For this purpose a 6 pole data
cable with conductors wired as pairs is required as well as an adapter cable from 10 pole flatwire to 9
pole D-Sub-plug. This cable's shielding has to be laid to the grounding plugs on both sides.
6. The analog outputs
The CamCon DAC16 has two 16 Bit analog outputs. They provide either 0 - 20mA, 4 - 20mA, 0 - 24mA
or, as an option, +/-10Volt signals. The maximum output current at +/-10 Volt is 10mA (not short circuit
proof). The load-resistance under current-output must not outrun 550
Ω
. The outputs are not potentially
free towards the voltage supply. the wiring of the analog outputs has to be done using shielded cables
and the cable's shielding has to be laid to the grounding plugs on one side.
6.1. Signal level of the analog outputs
The CamCon DAC16 module offers 4 possibilities of signal output for both analog outputs. These are:
0 - 20mA, 4 - 20mA, 0 - 24mA or opt/- 10Volt.
The adjusted signal levels are factory-provided marked by a cross at
the sticker label on the left side of the case.
OUT 2
OUT 1
If you want to change the signal level, the device has to
be opened. The case can be opened in the middle
using a screwdriver. On the solding side of the largest
printed circuit board two solding bridges for every
analog output, i.e. the analog output 1(OUT1) and 2
(OUT2), are located, which are named J1 to J4 in the
drawing to the right. J1 and J2 are used to adjust the
signal level for output 1 and J3 and J4 to adjust the
output level for output 2.
The drawing to the right shows
which solding bridges have to be
opened or closed, to get the
desired signal level.
Note:
For the +/-10Volt voltage output an
daditiona
l small wrapped printed circuit board is required.
7. Commisioning
Before the first commisioning, check the device's wiring carefully. See also chapter 5. Electrical
connections on page 5. For configuration and calibration of the analog outputs please regard in the
camswitches manual the chapter "unit configuration", sub-chapter "anolog outputs" and in the chapter
"system configuration" sub-chapter "special outputs".
