Schneider ASM84A001 Programmable Controller Module

The ASM84A001 serves as a programmable controller module for Schneider automation systems. This unit executes logic programs and manages I/O data transfers efficiently. Its rectangular frame measures 118 millimeters in width. The module height reaches 112 millimeters exactly. Depth stays at 85 millimeters. You will find this unit weighs approximately 0.56 kilograms. Therefore, installation requires a standard DIN rail clip mounted securely. One removable terminal block provides power input and basic I/O connections.

Physical Layout and Connectors

The front panel features a 2-line LCD display for diagnostic messages. You will find five push buttons for local configuration access. One RS-232 serial port connects to programming software on a laptop. A second RS-485 port supports Modbus network communication. Four status LEDs indicate run, stop, error, and power conditions.

Internal Design and Energy Storage

The ASM84A001 contains exactly 368 discrete components inside. An 820 microfarad capacitor bank filters the main power supply input. This bank holds enough charge for 18 milliseconds after power loss. The 16-bit processor runs at 16 megahertz for reliable execution. A lithium battery retains data memory for up to five years. EEPROM stores the user program without any battery backup required.

Operational Performance

This programmable controller module executes ladder logic from 64KB memory. It scans 1,000 instructions in approximately 1.0 millisecond. Moreover, the unit handles up to 128 digital I/O points directly. Two communication ports allow connection to HMIs and drives. The LCD display shows real-time system status and fault codes. Five buttons let you navigate menus without a programming computer. Consequently, you achieve dependable control for medium-sized machines. Schneider designed this module for AS series platform compatibility. Its industrial enclosure meets IP20 protection standards.

In summary, the ASM84A001 delivers reliable programmable controller performance. Use this module for factory automation or process control tasks. It balances processing power with cost-effectiveness. Order this controller module for your Schneider system upgrade.
