GE VMIVME-2170A 32-bit optically isolated digital output board

Basic Product Information

Product type: 32-bit optically isolated digital output board, specially designed and optimized for VMEbus, adopting dual Eurocard specifications, with 32 optically isolated high-level outputs.

Main functions: Implement digital output through VMEbus compatible logic, data control logic, and four 8-bit output registers, supporting 8-bit and 16 bit data transmission. The optocoupler isolates 32 outputs from each other and from VMEbus, supporting monitoring and non privileged data transmission.

Main characteristics

Equipped with 32 optically isolated outputs, the output current can be selected from 2.5mA or 300mA.

External pull-up voltage is provided to achieve maximum isolation, with on-site configurable pull-up resistors.

Capable of source or drain output, with a high output voltage tolerance of 30V in normal mode under low current options.

High isolation potential, capable of withstanding 1kV continuous voltage and 6kV pulse voltage, supporting positive or negative true options.

Supports 8-bit or 16 bit data transmission, with onboard DIP switches providing 14 bit board address selection. It adopts dual Eurocard format with front panel, allowing for on-site selection of non privileged or monitored short I/O transmission.

Application scenarios

Used for digital control of VMEbus, eliminating system grounding loops, controlling in high electrical noise environments, and controlling multi potential system components.

Ordering Options

Data polarity (A): 1 is positive true, 2 is negative true.

Output current (B): 0 is 2.5mA, 1 is 300mA.

CDE: All are 0 (reserved options for future use).

Special Sales Order (F): 0 is the standard VME front panel (without conforming coating), 1 is reserved, and 2 is the standard VME front panel (with conforming coating).

Connector data: Provides Panduit numbers for compatible cable connectors, strain eliminators, and PC board header connectors, also known as ITW/Pancon.

Functional characteristics

Compatibility: It is a standard dual height VME printed circuit board that is electrically and mechanically compatible with VMEbus.

Addressing scheme: It can be addressed to four 8-bit ports or two 16 bit registers, located on any 32-bit boundary within the short monitoring or short non privileged I/O space.

Board address: Selected by 14 onboard DIP switches, supports running in any available slot on the VMEbus backplane (except for slot 1).

VMEbus access: Address modification bits are decoded to support short monitoring or non privileged short I/O access, providing a single jumper to support this option, factory configured for short monitoring I/O access.

Data transmission types: D16, D8 (EO).

Access time: Maximum 250ns.
