Product Summary
The Allen-Bradley 1746-IB8 is a robust SLC 500 digital input module. It provides eight 24V DC sinking channels for general-purpose applications. This module delivers a nominal input current of 8mA for reliable signal detection. You can integrate it easily into new or existing SLC 500 systems.
Theme Option A: Product Procurement & Buyer Guide
Procurement managers need a module that offers both value and reliability. The 1746-IB8 meets this need with its broad operational voltage range. This module works with voltages from 10 to 30 Volts DC. This flexibility allows it to handle various power supply conditions. It simplifies your inventory by working with standard 24V DC systems. The module fits perfectly into the proven SLC 500 platform. This platform is widely used across many industries. You gain a reliable component for your control system architecture.
Application engineers require a module with clear electrical specifications. The 1746-IB8 draws only 50 milliamps from the 5V DC backplane. This low power consumption reduces strain on your power supply. The module dissipates just 1.3W of heat in total. This low thermal output allows for denser panel layouts. You can place modules closer together without overheating. The module also features a fast 8-millisecond signal delay for both ON and OFF states. This speed ensures your system responds quickly to input changes.
Safety and compliance are critical for any industrial purchase. The 1746-IB8 carries both UL and CE certifications. These certifications guarantee it meets strict safety standards. The module is also approved for hazardous locations. It works in Class 1, Division 2, Groups A, B, C, or D areas. This approval makes it suitable for oil and gas environments. The module has a dielectric withstand rating of 1500V AC. This high isolation protects your system from electrical surges. It ensures safe operation in demanding industrial settings.
Theme Option D: Expert Technical Evaluation & Performance Review
The 1746-IB8 module uses current sinking input technology. This design is standard for many modern PLC systems. Each input channel has a nominal input current of 8mA at 24V DC. This current level provides a strong, noise-immune signal. The module’s maximum OFF-state current is only 1 milliamps. This low threshold prevents false triggering from leakage currents. It ensures your system only sees a true ON signal. The maximum OFF-state voltage is just 5.0V DC. This tight specification further enhances signal integrity.
Environmental ruggedness is a key performance factor. The 1746-IB8 operates reliably in temperatures from 0 to 60 °C. It also functions in up to 95% non-condensing humidity. This tolerance allows for use in unconditioned factory floors. The module can withstand 2.5G of operational vibration. It also has a shock rating of 30G. These ratings ensure the module survives harsh conditions. It will not fail due to machine vibration or impact.
The module’s step response is also well-defined. The input step response is 100 milliseconds. The output step response is just 2.5 milliseconds. This combination allows for stable input reading and fast output reaction. The module has NEMA standard ICS 2-230-tested Noise Immunity. This testing confirms its ability to reject electrical noise. You can trust the 1746-IB8 to deliver accurate data in noisy environments. It provides a clear and reliable signal for your control logic.
