• Overload protection per channel
• Over-temperature protection
• Diagnostic LED per channel (16 LEDs, each representing 2 channels)

• Plug-in terminal connectors with spring clamps
• ABS plastic housing
• Front-facing LED status indicators (16 LEDs for 32 channels)
• X20 bus connector on bottom edge

Working Principle:
Digital output states from the controller are transferred via the X20 bus to the module. Each of the 32 channels is driven by an individual NPN transistor in a PNP sourcing configuration. When a channel bit is set to “1”, the transistor turns ON, sourcing 24 V DC to the load. When set to “0”, the transistor turns OFF. Each channel has an electronic fuse for short-circuit protection. Channel-to-channel isolation is maintained via optocouplers. The 16 front-panel LEDs each represent 2 channels (LED ON = both channels active).

Advantages & Highlights:

• 32 channels in a single compact module — highest density X20 digital output
• 0.5 A per channel with 8 A total capacity
• Electronic fuse per channel for fast fault protection
• PNP sourcing output — standard for European automation
• Reduced wiring and panel space compared to multiple 16-channel modules

Applicable Industries:

• Large-scale valve control (process plants)
• Indicator lamp arrays
• Relay and contactor banks
• High-channel-count discrete output in machine building
• Production line signal distribution
• Batch process control

Installation Requirements:

• Mount on DIN rail (TS 35 x 7.5 or TS 35 x 15)
• Connect to X20 base module or X20 system bus
• Wire PNP loads: +24 V → load → output terminal → 0 V return
• Use flyback diodes for all inductive loads
• Ensure total current does not exceed 8 A
• Use wire gauge appropriate for 0.5 A per channel (minimum 0.5 mm²)

Usage Precautions:

• Maximum 0.5 A per channel — do not exceed under any condition
• Total module current must not exceed 8 A
• Always install flyback diodes across inductive loads (relays, solenoids, contactors)
• Verify Active HIGH / Active LOW configuration in software matches physical wiring
• LED indicators represent 2 channels each — consult module documentation for exact LED-to-channel mapping
• Do not apply external voltage to output terminals
