Model 4998 Mini-OASIS Rack Offers Flexible Configurations for Multichannel Structural Testing



Most multi-channel structural testing configurations require less than 32 channels of front-end signal conditioning. Other laboratory tests may require a mixture of amplifiers for different sensor types. Similar requirements need test instrumentation with reduced rack size. That is why a low-profile, RS232 interlinkable mini-rack that can accept multiple card types and has expansion capability is needed for these applications

Endevco's Model 4998 Mini-OASIS Rack is designed to provide power and connectivity for up to four Model 428, 433, 436 and 482 OASIS Amplifier Cards. This unit is used bench top or mounted in a standard 19" cabinet. Each mini-rack without cards weighs 18.3 lbs. (8.3 Kg) and measures 3.5"H x 19.0"W x 16" D, an ideal size for most multi-channel test configurations requiring less than 32 channels of front-end signal conditioning.

The rear panel provides AC input power, RS-232 computer control, an external calibration input connector, and a 25-pin "D" output connector. The "D" connector has outputs from the 428, 433 and 436 amplifier cards only. This connector also allows for quick interface to data acquisition systems or connection to the convenient Endevco Model 36021 24-Channel BNC Output Breakout Panel.

Up to four mini-racks are inter-linkable, providing a maximum of 16 card slots, all being controlled from one EIA-RS-232 computer link. An internally mounted rack address DIP switch allows for quick rack address setting and baud rate selection (9.6 or 19.2 kbd).

Each mini-OASIS rack accepts any mixture of 400 series amplifier cards with hot-swap capability. The 400 series amplifier card family includes:

Model 428 - dual-channel amplifier card with isolation

Model 433 - non-isolated three-channel PE/ISOTRON® card with i-TEDS capability

Model 436 - three-channel non-isolated bridge amplifier card

Model 482 - eight-channel i-TEDS amplifier card.
