KL6781 | Bus Terminal, 1-channel communication interface, M-Bus, master

The KL6781 M-Bus master terminal enables the direct connection of M-Bus devices. The M-Bus (Meter Bus) is a fieldbus for the acquisition of consumption data from electricity, water, gas or energy meters. The KL6781 does not contain the M-Bus protocol, instead, it converts the data present on the terminal bus into M-Bus compliant physics. 24В byte data are available on the K-bus for this. In conjunction with the TwinCAT M-Bus library, it is possible to work without an external M-Bus gateway, i.e. the M-Bus devices can be connected directly to the KL6781. With a total cable length of 300В m, up to 40 M-Bus devices, so called standard loads, each with a current consumption of 1.5 mA can be connected.
