Technical Specifications:
Series: GE Fanuc 90-70 VersaGen I/O
Channel Count: 6 channels, 24V DC transistor outputs (NPN/Sink)
Output Voltage: 24V DC (Nominal)
Output Current: 0.5A per channel (Maximum), 5A total for all 6 channels
Output Type: NPN (Sink), Open collector
Turn-Off Time: < 0.5ms (Fast switching for solenoid control)
Backplane: VMEbus
Isolation: 500V DC channel-to-backplane
Operating Temperature: 0°C to +60°C
Firmware Revision: ES0622
Functional Features:
Per-Channel LEDs: Each of the 6 output channels has a green LED that illuminates when the output is active, providing immediate visual feedback.
Fast Switching: Transistor outputs switch off in < 0.5ms, ideal for controlling solenoid valves where fast de-energization is required to prevent sticking.
Overcurrent Protection: Each channel has independent electronic fuse that trips at 0.6A and auto-resets when the fault clears.
Short-Circuit Protection: Protected against output-to-ground and output-to-24V shorts.
Diagnostic Feedback: The module reports per-channel status (ON/OFF/FAULT) to the CPU via VMEbus every scan cycle.
ES0622 Configuration: This specific firmware revision includes optimized output timing and enhanced diagnostic reporting for high-speed sequencing applications.
Performance Parameters:
Output Leakage Current: < 1mA (per channel, when OFF)
Switching Frequency: > 1kHz (per channel)
Total Output Current: 5A maximum (all channels combined)
Isolation Voltage: 500V DC (Output to backplane)
MTBF: > 150,000 hours
