0-20mA 4CH Analog Input Modbus TCP Distributed I/O Module for DVP Series PLC

1. Overview

BL200 coupler is a data acquisition and control system based on a powerful 32-bit microprocessor design with Linux operating system and Modbus protocol support for quick access to on-site PLCs, SCADA, and ERP systems with built-in logic control, edge computing applications for IIoT and industrial automation applications.

The BL200 distributed I/O system consists of 3 parts: Coupler, I/O modules and terminal modules.

The communication between the node and the field devices (eg PLC) takes place via the Ethernet interface of the fieldbus coupler, and the communication between the fieldbus coupler and the I/O modules takes place via the local bus. The two Ethernet interfaces are internally integrated with a switch function, which can establish a linear topology without the need for additional switches or hubs.

The system needs to use the power module to provide 24VDC system voltage and 24VDC field voltage. Since two independent power supplies are used, the field voltage input interface and system voltage input interface of BL200 couplers are electrically isolated from each other.

When assembling fieldbus node modules, each I/O module can be arranged in any combination, and it is not required to be grouped by module type.

A terminal module must be plugged into the end of a fieldbus node to ensure correct data transmission.

2. Typical Application

High reliability, easy expansion, easy setting, and convenient network wiring, these capabilities let users efficiently adapt the BL200 I/O system to a variety of complex industrial solutions.

The I/O system is widely applicable to a variety of industrial solutions, such as Internet of Things, smart factories, smart cities, smart medical care, smart homes, smart transportation, data center environment monitoring, electric power, oil monitoring, automobiles, warehousing and logistics and other industries.
