Product Data Sheet
This product is part of Modicon TM3, a range of expansion I/O modules for Modicon plcs. This is a bus coupler for the Modbus serial link. It has 2 isolated RJ45s to connect to the Serial line bus. It allows plc to manage the distribution of up to 448 digital I/O and 112 analog I/O through a Modbus serial line. The data exchange rate is from 1.2kbits/s up to 112.2 kbits/s. It works via a 24VDC external power supply. It is an IP20-rated product. It measures 27mm wide 96.5mm high and 70mm deep. It weighs 0.100kg. It is a device designed to manage serial line communication when using expansion modules with a controller in a distributed architecture. It is certified by ce, cULus, EAC, RCM, UKCA, and EU RO Mutual Recognition. This module is compatible with Modicon M262/M241/M251/M221 logic controllers and is configurable with EcoStruxure machine expert software. It is delivered in 1 package (PCE type). It is mounted on a symmetrical DIN rail. Or with a specific kit for plate or panel mounting. The specially developed Modicon TM3 I/O system enables flexible and customizable expansion of the I/O terminals in all the controllers. From design and development to commissioning and maintenance, EcoStruxure Machine Expert is a complete machine-building solution.
