WARNING: Disconnect all power to the unit before
installing option cards.
Adding Option Cards
The PAX2 can be fitted with up to three option cards. The details for each
option card can be reviewed in the specification section below. Only one card
from each function type can be installed at a time. The function types include
Setpoint Alarms (PAXCDS), Communications (PAXCDC), and Analog Output
(PAXCDL). The option cards can be installed initially or at a later date.
COMMUNICATION CARDS (PAXCDC)
A variety of communication protocols are available for the PAX2 Only one
PAXCDC card can be installed at a time.
Note: For Modbus communications
use RS485 Communications Output Card and configure communication (
