Adding Option Cards
The PAX and MPAX series meters can be fitted with up to three optional plug-
in cards. The details for each plug-in card can be reviewed in the specification
section below. Only one card from each function type can be installed at one time.
The function types include Setpoint Alarms (PAXCDS), Communications
(PAXCDC), and Analog Output (PAXCDL). The plug-in cards can be installed
initially or at a later date.
