Schneider Electric engineered the PCE984381 as a central processing unit for the Modicon 984 Series automation platform. This module provides 16K of memory for handling complex logic and control applications. It delivers reliable performance for legacy industrial systems requiring stable operation.
Key Technical Specifications
The PCE984381 module features a robust form factor designed for 984 Series rack mounting. It measures approximately 220 millimeters in height and 180 millimeters in depth. This unit weighs around 1.5 kilograms for secure installation.
| Specification | Detail |
|---|---|
| Memory | 16K user memory for logic and data storage |
| Processing | Dedicated processor for ladder logic execution |
| Energy Storage | Internal battery backup for memory retention |
| Interfaces | Built-in communication ports for programming |
| Component Count | Single-board design with discrete logic components |
| Dimensions | 220 x 60 x 180 mm (H x W x D) approx. |
Moving to installation, this CPU mounts directly into the 984 Series rack. You insert the module into the designated slot and secure it with the locking mechanism. Consequently, the unit establishes immediate connection with the backplane and I/O modules.
Design and Application Focus
Engineers select the PCE984381 for its proven reliability in continuous processing environments. The design incorporates battery-backed memory to preserve critical data during power loss. Furthermore, the module supports standard Modicon 984 Series I/O architectures for seamless integration. This feature allows for straightforward upgrades or replacements in existing systems.
Unlike newer processors, this unit focuses on deterministic execution for time-sensitive applications. You can program the module using traditional ladder logic through compatible development tools. Additionally, the front-panel status indicators provide immediate feedback on processor operation and communication activity.
