DL8000 Preset Instruction Manual
3-8 Modules Revised February-2016
If required, you can calibrate the low end of the analog signal to zero
(refer to Chapter 7 in the ROCLINK 800 Configuration Software User
Manual) (for DL8000) (part D301259X012).
Note: The AI-16 module provides 16-bit resolution and uses a 24-bit
A/D converter. DIP switches on the AI-16 control the scaling
(see Figure 3-6).
You can configure the AI (+T) as either 12 or 24 Volts dc using jumper
J4 on the AI-12 module (see Figure 3-4). The AI modules can provide
isolated +12 Volts dc or +24 Volts dc field transmitter power on a per
module basis. For example, one module can provide +12 Volts dc for
powering low-power analog transmitters, while another module in the
same DL8000 controller can provide +24 Volts dc for powering
conventional 4 to 20 mA transmitters. See Figure 3-5.
