Product Description:

The ST-2748 expansion module is engineered to extend control capabilities with its 8 relay outputs. This module is designed for installation on 35 mm DIN rails, ensuring easy integration within existing systems for different industry needs. The module allows systems to control external devices over automated processes; designed within compact dimensions of 24 mm x 99 mm x 70 mm, the ST-2748 allows efficient use of space within control panels, and can easily be added without needing big allocation of space. The ST-2748 is robust and reliable, allowing for use in many applications.

Delving into the operational specifications, the ST-2748 module handles a wide range through output requirements. It capably manages 5–28.8 VDC @2.0A resistive; 48 VDC @0.8A resistive; 110 VDC @0.5A resistive; 250 VAC @2.0A resistive, providing versatility across different load types and voltage environments. This is equipped with a fast 10 ms output signal delay, both during ON-to-OFF and OFF-to-ON transitions. The fast responses are critical for time-sensitive applications, enhancing the overall precision via automated systems and reducing delays that could impact efficiency. The relay contacts allow a strong performance throughout their lifespan, rated for 300K cycles resistive and 100K cycles inductive, providing long-term reliability because the frequency with maintenance is less, reducing downtime across your operations.

For environmental considerations, the ST-2748 expansion module is built to preform while using in demanding conditions. Its operating temperature is -20°C to +55°C, allowing deployment over different industrial conditions. For storage, its temperature is from -40°C to +85°C, preventing damage throughout transportation or throughout non-use periods that are extended. Weighing only 200 g, it adds minimal load onto the installation framework, simplifying setup and reducing mechanical strain of the mounting apparatus. Power efficient, this device uses approximately 235 mA @ 5 VDC, which minimizes thermal output.
