Digital output expansion unit BR2/BR3

Description

Блок расширения выходов БР2/БР3 предназначен для подключения сигнальных цепей, коммутации сигналов, включения-выключения сильноточных цепей, управления системами оповещения, активизации систем аварийной сигнализации и т.д.

Рекомендуется для совместной работы с ПК, специализированными контроллерами и другими ведущими приборами, поддерживающими стандартный протокол обмена ModBus RTU в сети RS-485.

Basic functions and operating modes of the output expander:

• Expansion units are independent devices with an RS-485 communication interface with ModBus RTU protocol, which allows them to be used in conjunction with devices manufactured by our enterprise, equipment from other manufacturers, as well as directly under the control of a personal computer;
• the number of inputs / outputs can be increased by using several expansion units connected to one control device. This approach provides the expansion of the functionality of the meters / regulators, high reliability and interchangeability;
• the device is a slave device, i.e. normal operation of the device is possible only when connected to a master device (personal computer or microprocessor control system). The communication protocol of the device and the master is the Modbus RTU protocol in the RS-485 network;
• the user can programmatically reconfigure the BR using the master device, namely:
• device number on the network;
• data exchange rate;
• number of data bits;
• kind of parity;
• number of stop bits;
• initial state of discrete outputs;
• light indication of operating modes;
• easy mounting on a DIN rail.
