AEG AM-SA85-000 Modicon Serial Communication Module
- Product Introduction: This is a dual-port serial communication module for AEG Modicon 800 series PLC systems, enabling data exchange between the PLC and external devices (HMI, sensors, VFDs, SCADA systems) via RS-232 and RS-485 interfaces. It supports Modbus RTU/ASCII protocols, with baud rates up to 115200 bps and multi-drop capability, ideal for integrating legacy serial devices into modern industrial networks.
- Technical Specifications:
- Interfaces: 1×RS-232 (DB9), 1×RS-485 (screw terminal), auto-sensing for Modbus RTU/ASCII.
- Protocols: Modbus RTU, Modbus ASCII, configurable via programming software.
- Baud Rates: 300-115200 bps (configurable), parity (none/even/odd), data bits (7/8), stop bits (1/2).
- Multi-Drop: RS-485 supports up to 32 devices on a single bus, line length up to 1200 meters.
- Isolation: 2500 VAC between interfaces and backplane, surge protection ±2 kV.
- Processor: 32-bit communication processor, dedicated to protocol handling.
