The extension module EM-D-8/4-24DC-IFS is essential for handling more intricate tasks involving Interface system devices (IFS). It facilitates the integration of digital inputs and outputs, allowing for the processing of extra signals directly on-site.

Connection to the IFS gateway is accomplished via a DIN rail connector, permitting it to function as a slave device. The module operates efficiently within a rated control circuit supply voltage of 24 V DC, with a range of -20% to +25%, and supports a control supply current of 85 mA, which includes the load current from the outputs.

Specifications include a maximum switching current of 500 mA per output, ensuring robust signal processing capabilities. The device is built to endure environmental factors, with an operational temperature range from -35 °C to 50 °C and a storage temperature range of -35 °C to 80 °C. The housing, made from non-reinforced polyamide PA, meets the IP20 protection class, suitable for indoor installations.

For optimal performance, the module adheres to EN 61131-2 standards. Its compact dimensions (width: 22.5 mm, height: 99 mm, depth: 114.5 mm) allow it to be mounted easily on standard DIN rails, and it features a data rate of 76800 Baud, ensuring effective communication within the system.
