WAGO 750-407 2-Channel Digital Input Module (220 VDC)

The WAGO 750-407 is a 2-channel digital input module designed for the WAGO 750 Series modular I/O system. This module receives and processes 220 VDC control signals from field devices such as sensors, switches, and push buttons, providing reliable signal acquisition for industrial automation applications .

Key Features and Product Highlights

• 2 Digital Inputs: Provides two independent channels for 220 VDC signals, enabling compact signal acquisition in space-constrained applications .

• High-Side Switching Input Characteristic: Supports connection of 2-wire, 3-wire, and 4-wire sensors with functional ground contact, offering flexibility for various field device types .

• 3ms Input Filter: Built-in digital noise-rejection filter (3.0 ms) improves signal quality and reduces false triggering from electrical interference .

• Electrical Isolation: Complete isolation between field and system levels (2.5 kVAC / 3.5 kVDC dielectric strength) protects the control system from field-side voltage transients .

• CAGE CLAMP® Connection Technology: Tool-free spring pressure connections for solid and fine-stranded conductors (0.08–2.5 mm² / 28–14 AWG), ensuring fast, secure, and vibration-resistant wiring .

• Wide Voltage Range: Accepts 160–286 VDC for signal "1" (ON) and -3 to +100 VDC for signal "0" (OFF), providing reliable operation with varying input voltages .

• LED Status Indicators: Green LEDs (A, C) for each channel provide immediate visual confirmation of input status, simplifying troubleshooting and commissioning .

• Compact DIN Rail Design: 12mm width for space-efficient mounting on standard DIN-35 rails, maximizing I/O density in control panels .
