Description
Product Name: 1762-MM1RTC Allen Braley Output module
Product details:
The Allen-Bradley 1762-MM1RTC is a functional expansion module designed specifically for the MicroLogix 1200 controller series. It combines two critical functions into a single, compact unit: high-capacity memory backup and a real-time clock.
1. Product Overview
The 1762-MM1RTC is a “plug-and-play” memory module that installs directly into the processor. It is primarily used to ensure that the PLC program and critical data are preserved even during long-term power outages, while also providing the controller with the ability to track time and date for automated scheduling.
2. Technical Specifications
| Feature | Specification |
| Series | MicroLogix 1200 |
| Module Type | Memory Module with Real-Time Clock (RTC) |
| Memory Capacity | 8 KB |
| Clock Accuracy | $\pm 1$ minute per month at 25°C (77°F) |
| Operating Temperature | 0°C to +55°C (32°F to 131°F) |
| Storage Temperature | -40°C to +85°C (-40°F to 185°F) |
| Humidity | 5% to 95% (non-condensing) |
| Vibration/Shock | 30g peak acceleration / 10 to 500 Hz |
3. Key Advantages
-
Data Integrity: Provides a non-volatile backup of the user program and data, preventing system downtime due to memory loss.
-
Time-Stamping Capabilities: Enables the PLC to record exactly when events occur, which is vital for error logging and quality control.
-
Cost-Efficient: Combines two features (Memory + RTC) into one module, saving space and reducing the need for multiple components.
-
Portability: Allows for easy program transfer between different MicroLogix 1200 controllers without needing a laptop or specialized software on-site.
4. Product Applications
The 1762-MM1RTC is widely used in industrial environments where timing and data security are paramount:
-
Scheduled Operations: Lighting systems, HVAC control, or irrigation systems that rely on specific times of day.
-
Event Logging: Recording the precise time of machine faults or production cycles for later analysis.
-
Remote Stations: In locations where power might be unstable, the memory module ensures the program is never lost.
-
OEM Machine Shipping: Manufacturers can ship machines with the program pre-loaded on the module for easy field replacement.
5. Important Considerations & Precautions
Note: Always ensure the controller power is turned off before installing or removing the module to prevent electrical damage to the pins.
-
Write Protection: The module can be configured to be “read-only” to prevent unauthorized or accidental changes to the stored program.
-
Compatibility: This module is specifically for the MicroLogix 1200. It is not compatible with MicroLogix 1000, 1100, or 1500 series.
-
Environmental Limits: Avoid exposing the module to corrosive vapors or extreme temperatures outside its rated range, as this can drift the RTC accuracy.
-
Program Loading: You must configure the PLC processor via RSLogix 500 software to “Load Memory Module on Memory Error” or “Load Always” depending on your safety requirements.
