IDEC SX8R bus coupler module

IDEC Corporation has announced the SX8R bus coupler module, supporting the industry design trend of using smaller, decentralised control panels to simplify installations and reduce wiring complexity.

The IDEC SX8R bus coupler helps design distributed remote I/O systems or to expand the I/O count for controllers with limited base unit I/O points. Each SX8R supports up to seven I/O modules on the base unit and up to eight additional modules with the use of an expansion power supply, for a total of up to 15 I/O modules. A single SX8R can therefore support up to 480 discrete points (input or output), 120 analog inputs and 60 analog outputs, depending on the configuration.

The SX8R bus coupler module supports major open networks, including EtherNet/IP, Modbus TCP and CC-Link IE Field Basic. This means the SX8R works well with a current set-up without the need to replace other PLC makes and models, if the host device supports these major open networks. Multiple protocols are supported simultaneously.

The SX8R features one Ethernet port for the uplink connection to the host network and a second local Ethernet port for configuration purposes.

A compact form factor with direct or DIN rail mounting means minimal installation space. The 24 VDC power connector block is detachable and users can choose push-in or screw terminals. With a wide operating temperature range of -25 to +65°C, the SX8R is suitable for installation in challenging environments.
