(15) Description of component
The CPU & Power Module Type 9440/15-..-1. is an associated apparatus for use outside the
hazardous area and is used for data transmission between hazardous and non-hazardous
areas; in combination with the associated BusRail or the associated transmission cables and
the intrinsically safe I/O modules intended for this use, it forms the Bus system Type I.S. 1. Up
to two CPU & Power Modules and up to two BusRails, each with a maximum of 16 I/O
modules, can be inserted into a system.
The permissible ambient temperature range is –20 °C ≤ Ta ≤ 65 °C.
