DB –24C
7. DB-24C
24-Channel Open-Collector Output Board
The DB-24C has 24 channels of optically isolated digital outputs, arranged
into four isolated banks. Each digital output offers a darlington transistor and
integral suppression diode for inductive load. The board interface to field logic
signals, eliminating ground-loop problems and isolating the host computer
from damaging voltages. The DB-24C has one 37-pin D-sub connector, one
50-pin OPTO-22 compatible male header and one 20-pin male header.
The transistor is energized by applying a 5-voltage signal to the appropriate
input channels on the 50-pin header or 20-pin header or 37-pin D-sub
connector. Twenty-four enunciator LEDs, one for each transistor, light when
their associated transistor is activated. Because there is a 37-pin D-sub
connector on the board, the user may use it to interface to any TTL output
board. In other words, the user may use it as a general purpose
open-collector output board
7.1. Features
Group A (low nibble) and Group B(high nibble) has 4-channel high current
open-collector output each. The maximum load is 600mA per channels
Group A(high nibble), Group B (low nibble), C(byte) and Group D has
8-channel open-collector output each. The maximum load is 100mA per
channels.
Accept 20-pin connector to control 8 high current output channel and 8
low current output channels.
LEDs indicate each channel and power status.
