TERZ ZERO-RS Series

The ZERO-RS switches are highly optimized and cost-effective unmanaged Industrial Ethernet Switches, specifically designed for harsh industrial environments. With 5x and 8x RJ45 ports supporting Fast Ethernet (10/100 Mbit/s), they provide reliable network connectivity. Thanks to a rated voltage of 24 VDC (reverse polarity protected) and a voltage range of 6-36 VDC, they are extremely versatile. Their temperature range of -40 to 70°C and IP30 protection rating make them highly resilient. The housing, made of anodized aluminum/stainless steel, allows for space-saving and reliable mounting with a minimal installation width of only 17.5 mm. With features such as Auto-Negotiation, Auto-MDI-X, Auto-Polarity, and PROFINET compatibility, these switches are the ideal solution for demanding industrial network applications.
