ABB ES/M2.230.1 is the ABB i-bus® KNX Electronic Switch Actuator Module, 2-fold, 230 V. Its two overload-proof, noise-free and wear-resistant semiconductor outputs control electrothermal valve drives at 115/230 V AC/DC with up to 700 mA continuous current.

It snaps into a compatible RC/A4.2 or RC/A8.2 Room Controller slot. The host supplies the module interface, detects the inserted type and provides KNX communication, ETS parameterisation and manual functional testing. The module is not a standalone KNX device.

Function and Application

• Channels: 2 semiconductor outputs.
• Application: Silent switching of resistive loads, especially electrothermal heating or cooling valve drives.
• Host compatibility: RC/A4.2 and RC/A8.2 basis devices.
• Commissioning: Through the selected host Room Controller application; there is no separate module KNX address or product database.

Installation and Safety

The module terminals may carry hazardous mains voltage. Use the type-specific wiring diagram and observe the permitted load and current limits. Isolate the Room Controller and all field/load circuits before inserting, removing or wiring the module. ABB currently publishes IP54 for the product; treat this as an installed Room Controller system value, not a freestanding enclosure rating.

Use the model-specific technical data, instructions, diagrams and declarations below. Shared manuals may retain historical host names, while ABB's current compatibility records explicitly associate this module with RC/A4.2 and RC/A8.2.
