Product Description

The device is powered by power supply in the range of 12 to 24VDC/VAC and is able to communicate with up to 15 MBUS slave devices. The maximum length of the cable segment connected to the slave can be up to 1000 meters with a communication speed of 300 bps. The baud speed of the communication doesn’t have to be adjusted, the converter works independently from the communication speed of the master system.
