GE VMIVME2170A 332-102170-110 32-bit Optically Isolated Digital Output Board

Description

The GE VMIVME2170A 332-102170-110 is a 32-bit optically isolated digital output board designed specifically for GE’s VMIVME industrial computing systems. It is used to control external devices (such as relays and solenoids) based on digital signals from the VMIVME system. The board provides 32 optically isolated outputs, each capable of switching up to 2 amps of current.

Features

• Source or sink output capability with low current option
• High output voltage tolerance up to 30 V in normal mode
• High isolation potential: 1 kV sustained, 6 kV pulsed
• Positive or negative true options
• 8- or 16-bit data transfers
• On-board 14-bit address selection DIP switches
• Double Eurocard format with front panel
• Selectable nonprivileged or supervisory short I/O transfers
