Product Overview

• PN: XO16N1-B20 / XO16N1-C3.0
• Brand: Delta
• Series: DVP PLC Expansion Module
• Type: 16-channel NPN Transistor Digital Output Extension Module

• Function: Special expansion module for Delta DVP series PLC main units, expands 16 groups of NPN transistor switching output channels. Executes on-off control commands issued by the PLC host, outputs high-speed switching signals to servo drives, stepper motor controllers, pulse counters and small signal indicating lamps. Different suffix versions represent distinct firmware iterations, matching different generations of PLC host firmware to guarantee normal communication and logic control.

Core Features

• 16 independent NPN transistor output channels, each with LED status indicator for quick troubleshooting
• Transistor output supports high-frequency pulse output, suitable for motion control signal transmission
• Side bus direct docking with PLC mainframe or other expansion modules, automatically identified after connection
• DIN rail buckle installation, compact structure saving cabinet layout space
• Built-in freewheeling protection circuit to restrain reverse electromotive force damage from inductive loads

• B20 and C3.0 are only different in internal program version, consistent in hardware interface and wiring definition
