What is it?

• 4-Channel Opto-Isolator card
• 4N25 Optoisolators, 20% CTR
• Input /Output isolation
• Optional Transistor driver for Opto LED reduces required drive from 10 mA to under 500 uA and allows for a larger input range
• Input channels share their own common VCC/Ground (Optionally)
• Output channels share their own common Vcc/Ground (Optionally)
• 8-pin header for input
• 8-pin header for output
• Configuration Options
• Speed enhanced
• Bypass Input transistors
• Remove Output collector resistors
• 49x49mm
• (4) 4-40 mounting holes

Options

Bare or Assembled Board

• Bare Board (no parts) [Must select bare board in all options]
• Assembled Board

Input Drive

• Bare Board
• 3.3V Transistor Input
• 5V Transistor Input
• Direct Input - Common GND

Output Pull-up Resistors

• Bare Board
• Open Collector Output
• Optimized small resistor for speed (less output drive)
• Larger resistor (slower but more output drive)
