The RS-485 interface repeater DI-1PSM is designed for signal amplification on the RS-485 interface (BMS bus). This is required when the network distance exceeds a length of 1200 m and when more than 32 bus nodes exist.
Characteristics of DI-1PSM
Plastic enclosure for DIN rail mounting
Adjustable baud rate
Galvanic separation between the input and output circuit and the power supply
Supply voltage AC / DC 24 V ±20 %
Usages of DI-1PSM
Extension of the maximum possible bus length by 1200 m in BMS systems
(EDS, RCMS, MEDICS® systems)
Extension of the maximum possible bus nodes by 32
Protection against spikes by galvanic separation between the input and output circuit and the power supply
