Allen Bradley 1734-IB8K POINT I/O 8-Point Sink Digital DC Input Module

Product Overview

The Allen Bradley 1734-IB8K operates as a high-density digital input module within the POINT I/O family. This module interfaces with field-side sensors and switches, converting 24V DC sinking signals into logic-level data for the controller. The "K" designation signifies a conformal coated build, providing superior resistance against environmental contaminants. We guarantee this unit as 100% Brand New original factory equipment, ready for immediate deployment in distributed I/O architectures.

Technical Specifications

Engineering Advantages

• Environmental Shielding: The conformal coating protects internal circuitry from moisture, salt spray, and corrosive chemical vapors. This hardware enhancement extends the service life of the module in wastewater treatment plants, oil rigs, and chemical processing facilities where standard modules often fail due to oxidation.

• Granular Scalability: The ultra-compact POINT I/O footprint allows you to add I/O in increments of 8 points. This modularity reduces hardware waste and minimizes panel space requirements compared to traditional, bulkier PLC racks.

• Simplified Troubleshooting: Bright LED indicators on the front housing provide instant visual feedback for module status and individual point activity. This feature allows maintenance teams to isolate wiring faults or sensor failures without connecting a laptop.

• Rapid Installation: The module snaps directly onto the 1734-TB or 1734-TBS terminal base. This "Remove and Insertion Under Power" (RIUP) capability—when following proper safety protocols—shortens mean time to repair (MTTR) by allowing module swaps without dismantling the entire I/O stack.

FAQs

• What is the difference between the 1734-IB8 and the 1734-IB8K?

  The 1734-IB8K includes a conformal coating on the internal PC board. Electrically, they function identically, but the "K" version offers necessary protection for harsh, humid, or corrosive industrial atmospheres.

• Does this module require a specific terminal base?

  Yes. You must install the 1734-IB8K onto a 1734-TB, 1734-TBS, or 1734-TOP terminal base. Ensure you set the mechanical keying on the base to position 1 before inserting the module to prevent hardware damage.

• Can I mix conformal coated and non-coated modules in the same rack?

  Yes, the POINT I/O backplane supports a mix of module types. However, for maximum system reliability in harsh environments, engineers typically specify conformal coating for all components within the cabinet.

• Is this product factory sealed?

  Absolutely. We sell only 100% Brand New units in original Allen Bradley packaging. Each module includes the original factory seal, ensuring it has never been used or refurbished.
