WAGO Digital input 750-402

The 4 Channel Digital Input Module (part number 29K3931) is designed for use with Wago modular input/output systems. It features four digital inputs that operate at a voltage of 24 V DC, with a current consumption of 7.5 mA. The module includes a noise-rejection filter with options for different time constants, specifically 3.0 ms and 0.2 ms, depending on the variant. Electrical isolation is provided between field and system levels, rated at 500 V. The module supports a signal voltage range of -3 V to +5 V DC for logic low and 15 V to 30 V DC for logic high. It is compatible with wire cross sections from 0.08 mm¬= to 2.5 mm¬= (AWG 28 to 14) and utilizes CAGE CLAMP¬Æ technology for secure connections. The operating temperature range is from -20 ¬8C to +60 ¬8C, making it suitable for various environments. The module is compliant with several safety and EMC standards, including UL 508 and IECEx certifications, indicating its reliability for industrial applications.
