I-7590

  • 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
  • Allows updating firmware by the RS-232 port
  • Overcurrent and short-circuit protection on the M-Bus port

  • ±4 kV ESD to contact
  • Reverse polarity protection on power

Introduction

The I-7590 is specially designed for M-Bus slave device. It is a serial bus to M-Bus convertor. First, for serial bus, it offers RS-232, RS-422 and RS-485 three kinds of communication way. Second, the I-7590 has two rotary switches, one for serial port baud and the other for M-Bus port baud. Third, the I-7590 uses transparent transmission between serial bus and M-Bus communication. Through these three designs, it is easy to communicate with any standard M-Bus slave.

Application

The M-Bus (Meter‐Bus) is a bus optimized for the reading of measurement instruments like: energy counters, hot and cold water counters, gas, pressure, sensors and actuators, etc….
