Description
GE IC660ELB921J
- Technical Specifications:
- Channels: 16 independent digital input channels
- Input Type: 24VDC sourcing (PNP)
- Input Voltage: 18VDC to 30VDC (high), 0V to 5VDC (low)
- Input Current: ~3.5mA per channel
- Response Time: 1ms / 10ms (ON/OFF)
- Isolation: 500V RMS optical, 2 groups of 8
- Power: ~4W total
- Temperature: 0°C to 60°C
- Functional Features:
- 16 PNP input channels with LED indicators
- Two independent isolation groups (channels 1-8, 9-16)
- Backplane-powered, no external supply needed
- Compatible with Proficy Machine Edition
- Application Scenarios:
- European-standard sensor integration
- High-channel-count input aggregation
- Bottling line sensor monitoring
- Palletizing robot input interfaces
- Performance Parameters:
- Input Impedance: ~7kΩ
- Isolation: 500V RMS
- MTBF: >200,000 hours
- Bus Speed: 10Mbps
- Material Composition:
- Housing: UL94 V-0 ABS
- PCB: FR-4, conformally coated
- Connectors: Gold-plated edge connector, screw terminals
- Structural Features:
- 16 green LEDs on front panel
- Standard IC660 form factor
- Two isolation barrier zones
- Working Principle:
- PNP sensor provides +24V to the input when active. The module’s opto-isolator LED lights up, activating the phototransistor, which the CPU reads as logic “1”.
- Installation Requirements:
- VersaMax chassis (IC695/IC697)
- 18-26 AWG wire, shielded recommended
- Sensor +24V to module input, sensor 0V to common
- Usage Precautions:
- PNP sensors only — do not connect NPN
- Do not exceed 30VDC on any channel
- Ground shield at chassis end only
