ProLiant 7000 Backplane-E/J I/O expansion chassis and power supply that extends the D-bus beyond a fully configured IP112, IPV12, or ProLiant 7000 Backplane master chassis. Each ProLiant 7000 Backplane can accommodate up to ten I/O modules. No power restrictions limit the mix of I/O modules in the chas- sis, with the exception of A631 D/A converters in current mode. The D-bus is etched in the power half of the ProLiant 7000 Backplane chassis backplane, which also includes cable connectors for extending the D-bus between multiple chassis. A maximum of seven ProLiant 7000 Backplane expansion chassis may be interconnected to a single master chassis. Dimensions: 40 cm (15.75 in) by 48.3 cm (19 in ) by 27.2 cm (10.69 in) Mounting: Front- and rear-mountable in ProLiant 7000 Backplane and H9646 cabinet or in NEMA enclosures H332 Screw terminal mounting chassis that mounts in a H960 or H9646 cabinet or NEMA enciosure and holds the BC40 screw terminal assemblies leading to each of the I/O modules. Each chassis accommodates up to ten ProLiant 7000 Backplane screw terminal assemblies. Dimensions: 40 cm (15.75 in) by 48.3 cm (19 in) by 27.2 cm (10.69 in) Mounting: Front- and rear-mountable in ProLiant 7000 Backplane and ProLiant 7000 Backplane cabinets or in NEMA enclosures. ProLiant 7000 Backplane Thermocouple temperature reference panel. Provides accurate reference (cold junction) compensation for a maximum of six- teen two-wire thermocouple inputs to the A157 multiplexer or A020 A/D converter. The unit consists of an isothermal screw terminal assembly which accepts sixteen thermocouple inputs from the field; the signals are connected to the ProLiant 7000 Backplane used in conjunction with the ProLiant 7000 Backplane or A020 input channels by a ten- foot plug-in cable. Dimensions: 13.3 cm (5.25 in) by 48.3 cm (19 in) by 11.4 cm (4.5 in) Prerequisites: An ProLiant 7000 Backplane A/D converter or a multiplexer must be ordered sepa- rately for each ProLiant 7000 Backplane. An ProLiant 7000 Backplane multiplexer requires an A014 A/D converter as a prerequisite. Mounting Requirements: The ProLiant 7000 Backplane mounts in a 48.3-cm (19-in) rack in a cabinet, in a ProLiant 7000 Backplane enciosure, or directly against a wall. The ATR16 does not mount in an ProLiant 7000 Backplane or H334 chassis, and it does not require a BC40 screw terminal strip.
