Description
The GPIB-120A, detailed under part numbers 776564-01 through 776564-06, falls within the GPIB category as a GPIB Expander/Isolator. Compliant with the IEEE Standard 488.1, this device is designed to expand the maximum number of devices supported from 15 to 28 without requiring a rewrite of the user’s application software. It features a dual bus structure, referred to as A and B, which are isolated from each other. The GPIB-120A is capable of operating isolation up to 60 V and offers a breakdown isolation of 1600 V.
The connectivity is facilitated through connectors such as Amphenol, Cinch series 57 Microribbon, and Amp Champ, ensuring wide compatibility and ease of integration into existing systems. The front panel is equipped with seven LEDs, providing immediate visual feedback on the device’s status and operation. Furthermore, it accommodates 16 signal lines, comprising five interface management lines, three handshake lines, and eight data lines, catering to intricate communication protocols and data exchanges.
The power requirement for the GPIB-120A is rated at 27 VA, and it introduces a data transfer rate degradation of 250 ns per byte, which is a testament to its efficiency in facilitating communications across devices. The case dimensions are specified as 3.5 x 8.5 x 13.0 inches, constructed from UL94V-0 flame retardant polystyrene DOW 60875F or Noryl FN-215, ensuring durability and compliance with safety standards.
Operational integrity is maintained across a temperature range from 0° to 45° C and a relative humidity range of 5% to 95% (non-condensing), highlighting the GPIB-120A’s robustness and reliability in varied environmental conditions. This technical specification underscores the GPIB-120A’s capability to serve as a pivotal component in expanding and isolating GPIB networks, ensuring enhanced performance and flexibility for users.
