Functional Characteristics

• 16 Universal Channels: Supports positive/negative logic per module, adapting to global wiring standards and sensor types (proximity, limit, photoelectric switches).
• Dual Logic Wiring: Positive (source) and negative (sink) logic enables direct connection to PNP/NPN sensors without external converters.
• 1500 VAC Isolation: Protects backplane/CPU from field‑side surges, ground loops, and high‑voltage transients.
• 6–10 ms Response Time: Captures fast‑changing digital signals for real‑time control and monitoring.
• Per‑Channel LED Indicators: Instantly shows on/off status for quick troubleshooting; power/communication LEDs confirm module health.
• 0–30 VDC Input Range: Tolerates 24 VDC industrial power fluctuations, reducing false triggering from voltage spikes.
• BIU Power Efficiency: 75 mA typical BIU current draw minimizes backplane power load.
• Compact & Lightweight: 230 g, DIN rail mounting fits dense panels; hot swappable with Series 90‑30 chassis.
• Global Power Compatibility: 24 VDC ±10% field power works with standard industrial power supplies.
• Certified for Industrial Use: CE/UL/CSA compliance ensures safety in heavy industrial environments.

Application Scenarios

• Process Control: Chemical, oil/gas, water treatment; 16 channels monitor limit switches, level sensors, and valve position feedback, 1500 VAC isolation protects PLC from field noise, dual logic supports mixed sensor types.
• Machine Monitoring: Motors, pumps, compressors; 6–10 ms response time detects overload/fault conditions fast, per‑channel LEDs speed fault isolation.
• Manufacturing Automation: Assembly lines, packaging machines; 16 channels track photoelectric/proximity sensor status, dual logic integrates PNP/NPN sensors without adapters.
• HVAC & Building Automation: Chiller, boiler, air handler control; 16 channels monitor fan/motor on/off status, 0–30 VDC range tolerates building power fluctuations, BIU integrates with BMS via Modbus.
• Legacy System Retrofit: Upgrades Series 90‑30 PLCs with 16‑channel input expansion; preserves existing 24 VDC sensor infrastructure, dual logic supports global wiring standards.
• Remote I/O Racks: Distributed process monitoring; 24 VDC power and 230 g weight suit remote cabinets, BIU enables central data aggregation via backplane.
• Safety Interlocks: Conveyor, press, and robot safety systems; 16 channels monitor emergency stops and guard door switches, 1500 VAC isolation prevents common‑mode noise from triggering false safety trips.
