13.2 Analogue Output
Analogue Output Modules, when fitted, plug into the Four Channel
Control Card as shown below:
CAUTION
Connecting the analogue output to a loop voltage in excess of 40V
may cause permanent damage to the analogue output module.
The Analogue Output Modules provides a current loop output that
follows each sensor signal level. The loop output is isolated from the
control card supply and provides:
a. fully isolated operation per card when powered from an external
supply.
b. Non-isolated operation when powered from the System 57 power
supply.
The analogue outputs can be configured for 0 - 20mA or 4 - 20mA
output modes. Check the configuration sheet supplied with the system
