Features
Geared for M-Bus slave devices, the I-7590 is most useful as a serial bus to M-Bus convertor. It offers conversion from three communication types (RS-232, RS-422, and RS-485) to M-Bus. Two rotary switches allows for quick mode change from serial port baud to M-Bus port baud.
Application
- Serial Baud and M-Bus Baud can be configured separately
- Provides 10 kinds of Baud for default, 6 kinds of Baud for user-defined
- Supports up to 100 M-Bus slaves
- Provides transparent communication
- Watchdog inside
- Bias resistors of RS-422 and RS-485 adjust by switch
- Allows updating firmware by the RS-232 port
- Overcurrent and short-circuit protection on the M-Bus port
- 3750 Vrms photocouple isolation on the M-Bus port
- ±4 kV ESD to contact
- Reverse polarity protection on power
- Provide 3 LED indicators, PWR LED, MTX LED and MRX LED
- Dimensions: 72mm x 122mm x 33mm (W x L x H)
