1. MTN644592 KNX Binary Input: Advanced Signal Monitoring
A versatile interface that bridges the gap between conventional contact signals and sophisticated KNX software functions.
Hardware & Technical Specs:
- Input Capacity: 8 independent channels for floating contacts or push-buttons.
- Signal Feedback: Each input is equipped with a yellow LED to display the current voltage level, while a green LED indicates operational readiness.
- Voltage Generation: Internally generated SELV contact voltage (max 10V, clocked) and pulsing contact current (max 2mA).
- Installation: Designed for DIN rail TH35 mounting; 4 modules wide (approx. 70 mm).
- Wiring: Supports cable lengths of up to 50 meters per input; features plug-in screw terminals for fast installation.
KNX Software Functions:
- Control Modes: Switching, dimming, or blind control via 1 or 2 inputs.
- Blind Positioning: Supports 8-bit positioning values for precise shading control.
- Telegram Support: Pulse edges with 1-, 2-, 4-, or 8-bit, and 2-byte telegrams.
- Logic Functions: Includes short/long operation differentiation, cyclical sending, and 8-bit linear regulator functions.
- Safety: Features include initialization telegrams, disable functions, and configurable debounce times.
2. Seamless Integration and Reliability
The MTN644592 KNX Binary Input is designed for efficiency, eliminating the need for an additional data rail for bus connection.
- Easy Commissioning: Programmable via ETS without external configurators.
- Isolated Safety: Electrical isolation between the signal voltage and the KNX bus prevents interference.
- Versatile Use: Ideal for connecting window contacts, water sensors, or classic switches to a smart building network.
