Typical areas of use
- Optical and galvanic isolation of the interfaces of all MORSE system components, or other devices
- Interface conversion RS232 to RS422, or RS485
- Profibus
Benefits
- Supply voltage 5–30 V
- Protection of data lines against over-voltage
- Protection against polarity inversion of power supply
- Indication LED for data conductors
- Indication LED for supply voltage
- Speed up to 250 kbps
- Switching the direction of communication on the RS485 line done automatically or with an external signal with an arbitrary polarity
- Termination and definition of the idle state of the RS485 line done with internal switches
- Minimum dimensions, mounted on a DIN rail
- Profibus compatible
