5.2 Analogue Output Configuration
In addition to providing the connections for various connector types, the Input Module can also provide an analogue output. This
output mimics the signal detected so that it may be used by external equipment (e.g. chart recorders, data loggers) for a variety of
purposes.
NOTE: It is important to ensure that the Analogue Output is calibrated if in use (refer to ‘MCU Software Configuration and
System Calibration Manual’).

The Input Module sources current proportional to the detected gas level.
i.e.
zero gas
= 4mA
full scale = 20mA
The supply is taken from the internal PSU. Switch ON J12 and J14
