Product Description P/N: 1785-L40C
Description
The Allen-Bradley 1785-L40C is a PLC-5 series ControlNet processor module designed for deterministic industrial control applications. It features 48K of battery-backed SRAM and supports large-scale I/O configurations through ControlNet connectivity. The 1785-L40C draws 3.3 A at 5 VDC from the backplane and is intended for installation in 1771 I/O chassis systems.

Information About 1785-L40C
The 1785-L40C is a PLC-5/40 processor module developed by Allen-Bradley for high-performance control systems using ControlNet networks. It is built to manage extensive I/O architectures with fast and predictable data exchange across distributed devices. The module integrates processor, memory, and communication interfaces in a single chassis-mounted unit compatible with multiple Allen-Bradley I/O platforms. It is typically used in manufacturing, process automation, and large control systems where coordinated I/O control and networked communication are required.
Key Features:
- PLC-5/40 processor architecture: Designed for large and complex control applications.
- ControlNet communication: Supports deterministic, high-speed I/O data transfer.
- 48K battery-backed memory: Maintains user programs and data during power loss.
- High I/O capacity: Handles up to 2048 total I/O points or complementary I/O configurations.
- Multiple communication ports: Includes serial, ControlNet, and coprocessor interfaces.
- Fast I/O scanning: Optimized rack scan times across multiple baud rates.
- 1771 chassis compatibility: Integrates with legacy Allen-Bradley I/O systems.
The 1785-L40C delivers the reliability and precision required for large-scale PLC-based industrial control and networked automation systems.
