1756-IM16I-CC Allen Bradley

Description

Product Name: 1756-IM16I-CC  Allen Braley Output module

Product details:  

The Allen-Bradley 1756-IM16I-CC is a high-density, specialty digital input module from the ControlLogix platform. The “CC” suffix indicates that the module features Conformal Coating, providing an extra layer of protection against harsh environmental conditions.

1. Product Description

The 1756-IM16I-CC is a ControlLogix AC Digital Input Module providing 16 individually isolated channels. It is designed to interface with high-voltage AC sensors and switches, converting incoming AC signals into digital data for the ControlLogix controller.

• Platform: ControlLogix

• Module Type: Digital AC Input

• Protection: Conformal Coating (for chemical/moisture resistance)

• Isolation: Channel-to-channel isolation (prevents ground loops)

2. Technical Specifications

3. Product Advantages

• Conformal Coating: Specifically treated to resist contaminants, moisture, and corrosion, making it ideal for wastewater treatment, oil & gas, or mining.

• Individual Isolation: Because each channel is isolated, you can use multiple power sources on a single module without risk of cross-talk or ground loop issues.

• High Voltage Compatibility: Directly interfaces with 240V AC field devices without the need for interposing relays.

• Change of State (COS) Detection: Can be programmed to trigger a processor task immediately when an input changes, reducing latency.

• Hot-Swappable: Supports RIUP (Removal and Insertion Under Power), allowing for maintenance without shutting down the entire system.

4. Key Considerations & Precautions

• Wiring Safety: Given the high voltage (240V AC), ensure all power is disconnected before wiring or removing the Removable Terminal Block (RTB).

• RTB Selection: The module does not come with a terminal block; you must purchase the 1756-TBNH or 1756-TBSH separately.

• Heat Dissipation: Ensure the ControlLogix chassis has adequate ventilation, as high-voltage modules generate more heat than DC variants.

• Grounding: Proper earthing of the 1756 chassis is critical to ensure the safety and signal integrity of isolated modules.

5. Product Applications

The 1756-IM16I-CC is commonly used in heavy industrial environments where high-voltage AC signals are the standard:

• Power Plants: Monitoring high-voltage breakers and status contacts.

• Water Treatment: Interfacing with large AC-driven pumps and motor starters.

• Chemical Processing: Reliable operation in corrosive atmospheres (thanks to the CC coating).

• Manufacturing: Long-distance cable runs where AC signals are less susceptible to voltage drops compared to low-voltage DC.
