Distributed I\/O, often called remote I\/O, moves the inputs and outputs out of the central control cabinet and close to the sensors and actuators on the machine. A bus coupler collects the signals and sends them to the PLC, HMI or industrial PC over one fieldbus cable instead of dozens of individual wires. The result is less cabling, smaller cabinets and faster fault finding. SCN supplies the Weintek iR remote I\/O system, where one coupler handles up to 1,024 I\/O points and several nodes can be connected to the same master.<\/p>\n
The range has three couplers: iR-ECAT for EtherCAT (100 Mbps)<\/a>, iR-COP for CANopen (50 kbps\u20131 Mbps)<\/a> and iR-ETN for Modbus TCP\/IP (10\/100 Mbps)<\/a>. All run on 24 VDC, measure 27 x 109 x 81 mm and work from 0 to 55 \u00b0C. Pair them with a Weintek HMI panel<\/a>, find protocol converters under gateways<\/a>, or see all HMI and operator panels<\/a> and PLC systems<\/a>.<\/p>\n How to choose:<\/strong> start with the fieldbus your master already uses, count the digital and analog channels per machine section, and keep some spare channels for later changes.<\/p>\n Remote I\/O is a set of input and output modules mounted near the machine and connected to the controller over a fieldbus instead of individual wires. A bus coupler such as the Weintek iR-ECAT, iR-COP or iR-ETN passes the signals between the I\/O modules and the PLC, HMI or PC, which cuts cabling and makes the machine easier to extend.<\/p><\/details>\nFrequently asked questions<\/h3>\n
