DI-1DL

Product catalog summary

Product Description
The DI-1DL RS-485 interface repeater is designed to amplify signals on the RS-485 interface, specifically for BMS bus and Modbus RTU systems. It is essential when network distances exceed 1200 meters or when there are more than 31 bus nodes.

Applications

Extends bus length by 1200 meters in BMS systems like EDS, RCMS, and MEDICS®.
Increases the number of bus nodes by 31.
Provides protection against spikes through galvanic separation.
Facilitates resonant stubs implementation.

Device Features

Plastic enclosure suitable for DIN rail mounting.
Dynamic baud rate setting with automatic changeover.
Galvanic separation for overvoltage protection.
Operates on AC 85-260 V, 50-60 Hz.

Technical Data

Supply Voltage: AC 85-260 V, 50-60 Hz.
Power Consumption: 0.1 A/7 W.

_ Z BENDERRS-485 interface repeater for RS-485 bus extensionProduct description The RS-485 interface repeater DI-1DL is designed for signal amplification on the RS-485 interface (BMS bus, Modbus RTU). This is required when the network distance exceeds a length of 1200 m or when more than 3112 bus nodes exist. • 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 312 • Protection against spikes by galvanic separation between the input and output circuit and the power supply • Implementation of resonant...

a) When used in the BMS bus, the rotary switch is to be set to position 4 for baud rate/interference suppression. The rotary switch is located at the bottom of the device. b) Two DIP switches are available per bus segment to terminate the bus and to generate the required bias voltage. Both DIP switches must be switched on for activation. The termination is carried out as shown in the following example of a BMS bus system: D2 B = Bus device with terminating resistor = Bus device without terminating resistor Terminating resistor activated via switch on device (ON)* or external terminating resistor...
