The carrier is a platform on which the base modules are mounted. It is designed for DIN-
rail mounting, but may also be surface mounted by the use of available clips (see Section
4.1). The carrier will accept up to 16 module bases as well as one, or two, alarm modules
which can be added to provide contact closure for particular alarm events. The carrier
has channel by channel connections to the main control equipment via screw terminals.
It also has redundant power supply inputs and replaceable, plug-in, onboard fuses – see
table below for type and replacement part number.
