28000 Mainframes
Two mainframes are available for the 28000 system. For larger channel count configurations, the 28016B-M3 provides sixteen slots for signal conditioner cards. The smaller form factor of the 28008D-M3 8-slot chassis makes it more suitable for lower channel count systems or systems where portability is important. All 28000 mainframes accept field replaceable, low-noise AC power supplies to provide clean power to the signal conditioner cards. Binding posts at the rear panel are provided for connecting circuit and chassis grounds. Internal monitoring and reporting of system power supply levels is supported by the 28000 system architecture. To protect your investment, system temperature monitoring is provided and an audible alarm is sounded should the internal chassis temperature exceed factory limits or should a cooling fan operate out of specifications. Cards are inserted/ejected through the front of the 28000 system. Most analog input and output signal interfacing is at the rear panel of the 28000 chassis. The rear panels of the mainframes have cutouts to allow low-level signal input cables to be mated directly to the conditioner cards for optimal signal-to-noise performance. Cables are attached to the rear panel using screw locks. Cards may be inserted and removed from the system without disconnecting cables at the rear panel. The 28000 chassis have integrated 50-pin D-shell connectors at the rear panel to support outputs for 2 and 4-channel modules. Signal conditioning modules with greater than 4 channels per card furnish inputs and outputs via the rear panel cutouts, or in the case of the 28316B, via the card front panel. Precision Filters offers a wide variety of connector and cabling options in order to seamlessly integrate the 28000 into an existing cabling environment. Adapters to convert multi-pin connectors to BNC type are available as well as rugged cable assemblies and connector panels. Auxiliary output modules may be added to several 28000 cards to supply additional buffered outputs per channel with a variety of connector options. The 28000 mainframes are equipped with TEST and MONITOR analog busses that allow the user to insert test signals to any conditioner input and monitor any signal conditioner output without disconnecting any signal cables. Additionally, the TEST and MONITOR busses are used by the 28000 Test Subsystem for Factory Acceptance and Go/No-Go Tests. Mainframe Rear Panels
