• Front-facing LED status indicators (16 channels)
• X20 bus connector on bottom edge

Working Principle:
The controller sends digital output states via the X20 bus to the module. Each output channel is driven by an NPN transistor in a PNP (sourcing) configuration. When the controller sets a bit to “1”, the corresponding transistor turns ON, connecting the 24 V DC supply to the output terminal. When set to “0”, the transistor turns OFF. Each channel includes a fuse for short-circuit protection. Channel isolation is maintained via optocouplers.

Advantages & Highlights:

• 16 channels in a single compact module saves panel space
• 0.5 A per channel sufficient for most solenoid valves and small relays
• Electronic fuse provides fast short-circuit protection
• PNP (sourcing) output is standard for European automation systems
• Diagnostic LEDs simplify troubleshooting

Applicable Industries:

• Assembly line control
• Conveyor system control
• Packaging machine actuation
• Valve control in process automation
• General-purpose discrete I/O in machine building

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 loads between 24 V DC supply and output terminals (PNP sourcing configuration)
• Common return (0 V) connects to load, then to power supply negative
• Use wire gauge appropriate for 0.5 A per channel (minimum 0.5 mm² recommended)

Usage Precautions:

• Maximum 0.5 A per channel — do not exceed this rating
• Total module current must not exceed 4 A
• For inductive loads (relays, solenoids), use flyback diodes across the load
• Verify output polarity: PNP sourcing means load connects between output and 0 V
• Do not apply external voltage to output terminals
