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 31 bus nodes exist.

Features
• Plastic enclosure for DIN rail mounting
• Dynamic baud rate setting
• Galvanic separation between the input and output circuit and the power supply – overvoltage protection
• Supply voltage 85…260 V, AC 50…60 Hz

Applications
• 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 31
• Protection against spikes by galvanic separation between the input and output circuit and the power supply
