D301250X012) or the ROCLINK 800 Configuration Software User
Manual (for ROC800L) (part D301246X012).
Note: The AI-16 module provides 16-bit resolution and uses a 24-bit
A/D converter. DIP switches on the AI-16 module (see Figure 4-
6) allow you to select between current and voltage loop input.
You can configure the AI (+T) module as either 12 or 24 Volt dc using
jumper J4 on the AI-12 module (see Figure 4-4). The AI modules can
provide isolated +12 Volt dc or +24 Volt 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 ROC800 can provide +24 Volts dc for powering conventional
4–20-mA transmitters. Refer to Figure 4-5.
