Allen-Bradley 1756-IB16 SERA FW3.4 ControlLogix 16 Pt 12/24V DC D/I Module Made In USA
Product Overview
The Allen-Bradley 1756-IB16 SERA is a 16-point, 24 V DC sinking digital input module designed for the ControlLogix platform. Engineered for high-density discrete control, it provides fast, reliable ON/OFF detection for sensors, switches, and push buttons in packaging, material handling, and process skids. With conformal-coated circuitry (SERA version), on-board diagnostics, and hot-swappable design, the 1756-IB16 SERA ensures maximum uptime in harsh, dusty, or mildly corrosive environments.
Key Features & Benefits
• 16 individually isolated sinking inputs – flexible wiring for mixed-voltage panels
• 24 V DC nominal (10–31.2 V DC) – compatible with most field devices
• 0.7 ms filter time – fast response for high-speed counting or interlocking
• Conformal-coated SERA option – moisture & chemical resistance for severe-duty sites
• Removable 36-position (TBCH) or spring-clamp (TBS6H) terminal block – quick wiring changes
• On-board LED indicators for each channel – simplifies commissioning & troubleshooting
• Electronic keying & automatic device detection – prevents insertion errors
• Compatible with GuardLogix safety CPUs – supports Category 2/3 safety architectures
• UL Listed, CE, ATEX Zone 2, IECEx, Class I Div 2, RoHS compliant
Typical Applications
• High-speed packaging lines & palletizers
• Conveyor belt photo-eye arrays
• Water/wastewater lift-station level switches
• Chemical skid interlock & permissive logic
