Turck  has expanded its BL20 I/O system with a new gateway for serial Modbus communication.

It combines multiple series Modbus standards in one gateway.

BL20 is a new system for remotely collecting I/O signals. While I/O signals used to be brought back to a single large cabinet, modern distributed I/O approach is to use multiple cabinets placed near the I/O that they control. The BL20 is designed for this approach.

It has three parts: the gateway, the base and the electronic module. The gateway is the connection to the I/O network and is available in DeviceNet, Profibus-DP, CANopen and Ethernet.

The electronic modules are available in a variety of I/O signal types and counts while the bases provide a complete set of connections for field devices.

They also distribute, fuse and monitor local power distribution to save time, space and money compared to traditional PLC I/O. They are available in screw terminal or cage clamps.

The gateway supports both the Modbus RTU and the ASCII protocol. The user can also choose between either RS485 or RS232 for the physical interface.

Push-in terminals for connecting the fieldbus and power supply cables directly eliminate the need for any time-consuming preparation of the typical 9-pin SUB-D connectors.

The baud rate, address assignment, bus termination, and RS 232/RS485 can be set on the gateway using the DIP switches. Other functions such as ASCII mode and other baud rates can be configured using FDT/DTM with Pactware.

A mini-USB port can be used as a service interface.

Embedded in the Banner DX80 wireless system from the TURCK portfolio, the new gateway makes it possible to implement cable-free Modbus RTU communication.

The extended temperature range from -25 to 60ºC allows the gateway to be used in outdoor control cabinets.

The electronics are coated with a protective lacquer to provide protection from condensation. Up to 32 I/O modules can be connected to the compact IP20 gateways, and the BL modules can be used for connecting RFID read/write heads.

Users can arrange the same electronics modules in different fieldbus systems.
