Memory 128MB Proliant 1600 PC100, SDRAM, reg. RMS to dc multiplexer. Provides true RMS conversion of low- level ( ± 10 V) ac signals of either the sine wave type or any other periodical type (such as SCR-controlled signals). The Memory 128MB Proliant 1600 PC100, SDRAM, reg. is a 16-channel differential multiplexer which multi- plexes the inputs as pairs, thereby enabling two RMS readings to be taken simultaneously. Memory 128MB Proliant 1600 PC100, SDRAM, reg., A157, and AM158 multi- plexers must be mounted contiguously to their corresponding A014 A/D converter in the same master or H334 expansion chassis. Industrial Systems Industrial I/O Products Memory 128MB Proliant 1600 PC100, SDRAM, reg. 12-bit isolated, four-channel D/A converter. Contains four group-isolated, 12-bit digital-to-analog converters. The module is optically isolated, offers a choice of current or voltage out- puts, and is capable of retaining its output states during a power failure. The user must provide external ± 24 V power to the Memory 128MB Proliant 1600 PC100, SDRAM, reg. module to operate in the retentive mode. When the retentive feature is not implemented and the module is used in the current mode, the Memory 128MB Proliant 1600 PC100, SDRAM, reg. should be configured in an IP112/IPV12 master chassis or H334E/J expander chassis. If the entire chassis is to be filled with Memory 128MB Proliant 1600 PC100, SDRAM, reg., leave one slot unused; the remaining nine slots can then be filled with cur- rent-mode Memory 128MB Proliant 1600 PC100, SDRAM, reg.. The unused slot should be filled with an Memory 128MB Proliant 1600 PC100, SDRAM, reg. continuity module unless it is the last slot in the sub- system. Or use five or fewer current-mode Memory 128MB Proliant 1600 PC100, SDRAM, reg. modules per chassis; the remaining slots can be used for any other IP I/O module types, including voltage-mode Memory 128MB Proliant 1600 PC100, SDRAM, reg..
