Product Introduction

45C-409 (45C409) is a control processor module of the Reliance (now ABB) AutoMate 40X series PLC, used in conjunction with the 45C-400 logic processor to form the core of the 40X controller, responsible for system bus control, I/O management and data processing. It is no longer in production and is only available in refurbished, surplus or NOS new products for maintenance of old systems.

Model Interpretation

45C: Prefix of the Reliance AutoMate 45C series control component.

409: Represents the 40X system control processor module.

45C-409 = 45C409: The hyphen is the industrial standard notation, and the two are exactly the same.

Suffix (A/B/C etc.): Hardware version, with the core function remaining unchanged.

Technical Parameters

Module Type: Control Processor (CPU Coordinated Module).

Compatible System: AutoMate 40X Controller (paired with 45C-400).

Maximum Digital I/O: 1024 points (coordinated with 45C-400).

Built-in Memory: 8K×16-bit non-volatile application memory.

Memory Expansion: Supports 2 expansion cards, up to 104K×16 bits.

Backplane Power Supply: 5VDC from the backplane of the 45C rack.

Weight: Approximately 0.88kg.

Operating Temperature: 0°C to +55°C.

Installation Slots: Occupies 1 standard 45C series slot.

Interface and Communication Configuration

Installation Method: Insert into the 45C rack after power off, fixed with screws, and do not allow hot swapping.

Bus Interface: Interacts with 45C-400 and I/O modules at high speed through the backplane bus.

Status Indicators: The panel contains power, operation, and fault LED indicators, displaying the status in real time.

Configuration Method: No DIP switches, parameters are configured by the programming software, and the program is downloaded to 45C-400.

Communication Rate: Collaborates with 45C-400, backplane bus rate 250Kbaud. Core function

System bus control: Manages the 40X system backplane bus and coordinates data transmission among various modules.

I/O expansion management: Supports up to 1024 digital I/O points, suitable for small and medium-sized automation systems.

Memory expansion: Provides large-capacity non-volatile memory, supporting complex program and data storage.

Dual processor collaboration: Shares tasks with the 45C-400 logic processor to enhance system processing efficiency.

Fault self-check and alarm: Built-in diagnostic function. When a fault occurs, indicator lights alarm and record error information. Applicable scenarios

Replacement of the core of the old system: Direct replacement of the aging or damaged control processor in the AutoMate 40X system.

Control of medium and small production lines: Core control for old production lines in industries such as automotive parts, packaging, and textiles.

Equipment renovation and upgrade: Retain the original I/O modules and wiring, only replace the processor module to reduce the renovation cost.

Redundant and highly reliable system: As the control core in the dual-processor architecture, ensuring the stable operation of the system.

User and maintenance instructions

Before installation, all power supplies of the system must be cut off. Confirm that the backplane slots are clean and free of foreign objects, insert and then tighten the fixing screws.

Pairing and verification: Before powering on, confirm compatibility with version 45C-400 and download the matching system program.

Daily inspection: Regularly check the running and fault indicator light status, keep the module surface clean and free of dust accumulation.

Heat dissipation maintenance: Ensure good ventilation of the rack, avoid blocking the module heat dissipation holes, and prevent overheating and system crash.

Fault handling: When the indicator light is abnormal, first check the backplane power supply and connection; if the program reports errors, re-download or troubleshoot the logic; if the hardware is damaged, replace the module.

Safety regulations: Before disassembling, maintaining, or replacing, completely cut off the power supply. Do not operate with power on to avoid the risks of electric shock and module burnout.
