ABB DI620 Digital Input Module
The ABB DI620 (Part Number 3BHT30002R1) is a high-density 32-channel digital input module designed for integration within ABB Freelance DCS and Symphony Plus control platforms. Operating on a nominal 24 V DC input voltage (18 to 30 V DC range), it interfaces field binary devices—such as limit switches, proximity sensors, and relay contacts—directly with the system control architecture.
Channel Configuration and Signal Processing
The module supports both sink and source input wiring topologies across its 32 channels. Channel circuitry provides an input impedance of 4.7 kΩ with current draw ranging between 2 and 24 mA. Signal conversion features a typical response time under 5 ms, which can be configured down to 1 ms in fast mode. Individual front-panel LED indicators display real-time logic states for each channel to streamline loop testing and field diagnostics.
Protection Capabilities and Mechanical Specifications
Galvanic isolation rated at 2500 V between the input channels and the internal system bus protects the central processor logic from field-side electrical surges. The DI620 supports hot-swapping under powered rack conditions and includes onboard overvoltage protection. Rated for operation from –25 deg C to +70 deg C, the DIN-rail-mountable module measures 252 × 273 × 40 mm (W × H × D) and weighs 1.17 kg.
