The WebEasy eBMS/IO 4DO is an I/O module that operates locally or remotely, featuring four independent digital relay output channels. Each channel supports 250V AC and has a current rating of 16A, with a change-over contact configuration. A yellow LED on each output shows the status of connected devices.

This IP20 rated module mounts easily on standard TS35 DIN rail or directly onto a surface. Its cascadable design allows for simple connections of power and 2-wire RS485 Modbus communications without extra wiring. Rotary switches beneath the top cover enable straightforward Modbus address adjustments. A bi-colour LED displays the communications status for effective monitoring.

The 4DO includes a 2-wire RS485 port for Modbus network connections, compatible with the JACE® controller. It supports networking through TCP, RS485, or a combination of both, allowing flexibility in system design. This module integrates into any system with a Modbus interface, with palette files available for Tridium AX and N4.

The WebEasy eBMS/IO 4DO serves Building Management Systems (BMS) and monitoring applications, providing reliable control and monitoring across various settings.
