Tinycontrol tBsW5port Expansion Board with 1-Wire and 5x Terminal, I2C for LAN controller LK3 and LK4

Reliable solution for connecting up to five temperature sensors DS18B20 to LK control units significantly simplifies the installation and management of the system. Splitting the 1-Wire bus into 5 separate ports allows clear connections without complicated wiring, while RJ-12 input connector ensures quick connection to the control unit. Each output provides stable 5V power, a data line, and ground, ensuring trouble-free operation.

Installation is easy thanks to design for DIN rail 35 mm, ideal for distribution boards. Connecting wires is facilitated by spring terminals with locking, which saves time during installation and maintenance. Support for wires with a cross-section of 0.2–0.75 mm2 increases flexibility of use. The device is fully compatible with all versions of tinycontrol LK units, and when using twisted pairs from an Ethernet cable, it achieves optimal transmission properties.
