The level converter WTX631-GA0090 is a communications interface for reading data from up to 250 M-bus devices (simple M-bus loads). It consists of a level converter/repeater and the associated power supply.
The data is read:
- Locally with the ACT531 PC software via the RS-232 interface
- Via an M-bus master (WTV776 or predecessor) over line M1M2 (repeater)
- Via an M-bus master (WTV776 or predecessor) over line ABC (level converter)
- Via Desigo CC over an RS-232 or RS-485 interface
Up to six level converters can be connected in parallel to a WTV776 on an M-bus network. Up to six level converters (max. five repeaters) can be connected in series to bridge large distances.
Up to 250 M-bus devices can be connected to each WTX631 level converter.
The level converter can be used:
- As a single component on an M-bus network with up to 250 M-bus devices.
- To extend an M-bus network to up to six level converters connected in parallel.
- As a power supply for the WTV776.
You can also use the level converter, at your own risk, as an interface to suitable software and devices from third-party manufacturers.
The level converter is galvanically isolated. It is protected against short circuits.
