Level converter M-Bus / RS232
HD67020
Interfaces:
1x M-Bus, 1x RS232
- Level converter for professional applications
- High temperature range from -40 °C to +70 °C
- Up to 10 M-Bus slaves can be connected
- Galvanic isolation
The HD6702003 and HD6702010 level converters enable communication between M-Bus slaves and a serial RS232 interface. They convert the M-Bus physics to a serial interface. The protocol properties are not affected. The converters can be put into operation without configuration software. The same baud rate is used on the M-Bus side as on the serial side. The converters automatically detect the baud rate on the serial side. Top-hat rail mounting and screw terminals ensure fast, secure installation and problem-free wiring of the device.
Interfaces:
1x RS232 (screw terminal, 3-pin)
1x M-Bus (screw terminal, 2-pin)
Data rate :
M-Bus: 300 bps to 38,400 bps
Serial: 300 bps to 38,400 bps
Parity: none, even, odd
Echo of RS232 data:
The responses from the M-Bus slaves are preceded by the echo of the RS232 data sent.
This echo function cannot be deactivated.
If this is not desired, the level converter HD67021 must be used as an alternative; this does not send back an echo of the RS232 data.
