Description

This component is a signal interface module designed for use in industrial automation systems. It provides isolation, conversion, and transmission of electrical signals between different control system elements. Its primary purpose is to adapt signal levels and formats to ensure compatibility across devices without interference or data loss. ### Electrical Specifications Supports input voltages ranging from 24 VDC up to 30 VDC for standard operation. Isolation voltage: Rated at up to 2 kV for galvanic separation between input/output sections. Signal types supported: digital/analog depending on connected configuration (refer to datasheet). ### Mechanical Features DIN-rail mountable — compatible with TS35 rail types per EN 60715 standards. Enclosure material: Polycarbonate (PC) housing; flame-retardant rating UL94 V-0. Dimensions (LxWxH): Approximate size, 80 mm x 12 mm x 98 mm — standard slimline form factor. #### Technical Notes / Limitations: - Operating temperature range: -20°C to +55°C. - Relative humidity tolerance under max-load conditions: Max limit of ~85%, non-condensing. - Wiring terminals allow conductor cross-sections from ~0.14–1 square millimeters with ferrules fitted. - Not suitable if exposure thresholds exceed peak transient voltages listed in IEC standard tables.
