Siemens ET 200AL Series Communication Module, IP67, RS485 Communication Protocol - 6ES7157-1AA00-0AB0

This communication module provides a rugged Interface for fieldbus connections in industrial control installations, enabling serial data exchange via RS485 and intended for installation with IM 157-1 DP modules. It operates from a 24 V supply and is designed for harsh environments where an ingress‑protected enclosure is required, while meeting required CE and UKCA approvals for use in compliant systems.

Features and Benefits:

• RS485 Interface supports robust multi‑drop communication
• 24 V supply enables direct integration with standard control power
• IP67 enclosure allows installation in wet or dusty locations
• No hazardous‑area certification simplifies non‑Ex zone deployment
• CE and UKCA marking confirms conformity with regional standards

Applications

• Used with IM 157-1 DP for decentralised I/O networks
• Suitable for ET 200AL accessory installations in cabinets
• Ideal for fieldbus links requiring RS485 signalling
• Can be used for outdoor or wash‑down automation points

What supply voltage is required for operation?

It requires a 24 V supply for normal operation.

Which communication protocol does it use for field connections?

It communicates over the RS485 serial protocol.

Is the enclosure rated for exposure to water and dust?

The enclosure is IP67 rated for protection against dust ingress and temporary immersion.

Can it be deployed in certified hazardous‑area zones?

It does not carry hazardous‑area certification and is for use outside Ex zones.

What approvals indicate conformity with regional regulations?

It carries CE and UKCA approvals.
