5. Terminal alllocation

.
5.1. Terminal allocation of the power supply
Terminal 1 0V voltage supply
Terminal 2 0V voltage supply
Terminal 3 +24V voltage supply
Terminal 4 +24V voltage supply
5.2. Terminal allocation of the analog input 1
Terminal 5 signal ground GND (0V)
Terminal 6 analog signal 1
as voltage or current signal
(see also chapter 6. Configuration)
Terminal 7 reference voltage output (+4.096V or +5V)
(see also chapter 6.2. Reference voltage supply)
5.3. Terminal allocation of the analog input 2
Terminal 8 Signal ground GND (0V)
Terminal 9 Analogsignal 2
as currency - or voltage signal
(see also chapter 6. Configuration)
Terminal 10 reference voltage output (+4.096V or +5V)
(see also chapter 6.2. Reference voltage supply)
Note:
All analog signals must be laid shielded and the cover has to laid to ground
on both sides.
5.4. Pin allocation of the external interface
The analog - digital - converter AWA/2X12B has an external interface via which the data transfer with
the CamCon device is done. Via the interface input the data exchange with the CamCon e.g.
DC16/50/90 or DC115 is done. Via the interface output, the data exchange with another analog - digital
- converter or a CamCon DC91 output-expansion is done. By this series connection several devices
may be connected to a CamCon. A shielded 6 pole data cable with conductors wired in pairs is
required. The maxium wiring disatance is 300 meters, the data exchange is done potentially free via
optical couplers.
