The Schneider Electric MTN644592 is a KNX binary input module designed to integrate up to eight conventional push-buttons or potential-free contacts into a KNX bus system. Key features include:

• Input Channels: 8 inputs for connecting standard push-buttons or floating contacts.

• Signal Voltage: Internally generates a SELV (Safety Extra-Low Voltage) signal, electrically isolated from the bus, ensuring safe operation.

• LED Indicators:

• Yellow LEDs display the input voltage level for each channel.

• A green LED indicates the device’s operational readiness once the application is loaded.

• Installation: Designed for DIN rail TH35 mounting according to EN 60715 standards, facilitating easy integration into electrical panels.

• Bus Connection: Integrated bus coupler with plug-in screw terminals; a data rail is not necessary.

• KNX Software Functions:

• Switching, dimming, or blind control via 1 or 2 inputs.

• Positioning values for blind control (8-bit).

• Pulse edges with 1-, 2-, 4-, or 8-bit telegrams.

• Differentiation between short/long operation.

• Initialization telegram.

• Cyclical sending.

• Pulse edges with 2-byte telegrams.

• 8-bit linear regulator.

• Disable function.

• Break/make contact.

• Debounce time.

• Electrical Specifications:

• Contact Voltage: Max. 10 V, clocked.

• Contact Current: Max. 2 mA, pulsing.

• Cable Length: Up to 50 meters.

• Dimensions: Width of 4 modules, approximately 70 mm, optimizing space within distribution boards.

• Color: Light grey, ensuring a neutral appearance suitable for various installations.
