Siemens PLC Expansion Module Analogue for use with ET 200M

This PLC expansion module provides eight analogue outputs for integration with ET 200M systems and is designed for use on DIN-rail PLC installations. It operates from a 24V supply and supports two-wire current actuators with HART-capable outputs, offering local diagnostic buffering and firmware update functions when paired with compatible Interface modules. The unit is intended for industrial control environments requiring multi-channel analogue signalling and diagnostic visibility.

• 8 analogue outputs enabling multiple current-controlled loops
• 24V supply minimises cabling complexity for control racks
• 16-bit resolution for precise output Value representation
• HART-AO mode support for auxiliary variable communication
• 500V DC isolation test enhances separation from backplane

• Used with ET 200M for distributed I/O expansion
• Suitable for process control requiring current outputs
• Can be used for HART device communication and diagnostics
• Ideal for systems needing local diagnostic buffer timestamps

It provides 0 to 20 mA and 4 to 20 mA current output ranges for each channel.

Current outputs accept two-wire connections and support up to 750 Ω load impedance.

A group error LED indicates faults and the module supports substitute values and diagnostic alarms.

The unit has IP20 protection and carries CE, EAC, UKCA and UL approvals.

In HART-AO mode the module has a 50 MS Basic execution time for all channels and supports HART auxiliary variables.
