The SICK WL8G-P2231 is a Type 4 safety light curtain from the deTec4 Prime series, designed for access protection and perimeter guarding of machinery. It creates a vertical curtain of infrared light beams. When any single beam is interrupted, it sends a stop signal to the machine's safety control system, preventing access to a hazardous area and protecting personnel.

The Schneider 140CRP93200C is a high-performance RIO head-end adaptor module designed for seamless integration into the Modicon Quantum automation platform, facilitating efficient data exchange and control in industrial settings.

Technical Parameters Category Specification Model MTL5081 Product Type 2-Wire Loop-Powered Isolator Input Signal 4-20 mA (standard process current signal) Output Signal 4-20 mA (isolated replica of the input) Power Supply Loop-Powered. Operates from the signal loop itself, typically requiring a minimum loop voltage (e.g., 12-30 V DC) at the input. Isolation Galvanic Isolation between input and output circuits. A typical isolation rating is 1500 V AC. Key Features Ground Loop Elimination Yes. Prevents stray ground currents from affecting the signal. Noise Suppression Provides common-mode noise rejection. Intrinsic Safety When used with an associated intrinsic safety barrier, it can be part of a loop for hazardous areas. Accuracy Typically ±0.1% to ±0.2% of span. Load Capacity The maximum output load (e.g., 500-750 Ω) is limited by the available loop supply voltage. Mounting Standard 35 mm DIN rail. Operating Temperature -20°C to +60°C
