1756-IB16D-CC Allen Bradley

Description

Product Name: 1756-IB16D-CC  Allen Braley Output module

Product details:  

The Allen-Bradley 1756-IB16D-CC is a specialized digital input module from the ControlLogix platform. The “CC” suffix indicates that this specific model features Conformal Coating, providing enhanced protection against harsh environmental conditions.

Here is a detailed breakdown of the product:

## Product Overview

The 1756-IB16D-CC is a Sinking/Sourcing 24V DC Diagnostic Input Module. Unlike standard input modules, the “D” designation signifies its Diagnostic capabilities, allowing the system to detect specific wiring or hardware faults, such as open circuits or short circuits, in real-time.

## Technical Specifications

## Key Advantages

• Enhanced Reliability: The Conformal Coating protects the internal circuitry from moisture, salt spray, dust, and corrosive chemical vapors, making it ideal for heavy industrial use.

• Proactive Maintenance: The diagnostic features allow the PLC to identify exactly which wire is broken or if an external power supply has failed, significantly reducing Mean Time to Repair (MTRR).

• Flexibility: It supports both Sinking and Sourcing configurations, allowing it to interface with a wide variety of field sensors (PNP or NPN).

• Hot-Swappable: Supports Removal and Insertion Under Power (RIUP), meaning you can replace the module without shutting down the entire system.

• Change of State (COS): Can be programmed to send data to the controller only when a value changes, reducing backplane traffic and improving system performance.

## Critical Considerations & Precautions

Note: Always ensure that the Removable Terminal Block (RTB) is correctly keyed to prevent accidental insertion of the wrong voltage into the module.

1. RTB Compatibility: The module does not come with a terminal block. You must use either the 1756-TBNH or 1756-TBSH.

2. Diagnostic Thresholds: To use the “Open Wire” diagnostic feature, a small amount of leakage current must be present. Some ultra-low power sensors might trigger a false “Open Wire” error.

3. Environmental Ratings: While conformally coated, the module should still be housed in an appropriately rated NEMA or IP enclosure to prevent physical damage.

4. Wiring Polarity: Ensure the 24V DC power supply is correctly regulated to avoid “Field Power Loss” diagnostic trips.

## Common Applications

• Chemical and Oil & Gas: Where corrosive atmospheres are present (benefit of Conformal Coating).

• Automotive Assembly: High-speed lines where diagnostic feedback is crucial to prevent long downtimes.

• Wastewater Treatment: Environments with high humidity and potential exposure to gases like Hydrogen Sulfide ($H_2S$).

• Critical Infrastructure: Any system where knowing the difference between a “sensor being off” and a “broken wire” is mission-critical.
