KOYO D4-32TD2
Product Name: DirectLOGIC DL405 32-Point DC Sourcing Output Module
Product Introduction
The KOYO D4-32TD2 is a discrete transistor output module for the DL405/DirectLOGIC programmable logic controller system. It converts controller logic signals into 32 sourcing DC output channels for controlling industrial loads such as solenoids, indicator lights, and other low-power DC actuators.

Structural Characteristics
Form Factor: Single-slot DL405 module
Output Arrangement: 32 outputs divided into four groups of eight
Wiring Interface: Field wiring connects to the module terminal block or compatible pre-wired connector.
Status Display: Front-panel LEDs provide channel-level indication.
Working Principle
The CPU sends output status information across the DL405 backplane. The module switches the corresponding external DC load voltage to each output device through protected transistor circuits. Each isolated common group allows different loads or supply arrangements where supported by the application.
Installation Requirements
Rack Compatibility: Install in a compatible DL405 base or rack.
Power Supply: Connect the correct external load voltage before energizing outputs.
Common Distribution: Distribute high-current loads across the four common groups.
Wiring Check: Verify sourcing output polarity and load current before applying power.
Secure Mounting: Seat the module fully on the backplane and tighten all terminations.
Usage Precautions
Load Rating: Do not exceed the published current rating for each point, common, or module.
Inductive Loads: Use appropriate suppression components for solenoids, contactors, and relay coils.
DC Only: This module is intended for DC loads, not directly for AC switching.
Input Compatibility: Verify that downstream devices are compatible with sourcing/PNP outputs.
Hot Replacement: Remove backplane power before replacing the module unless the system explicitly supports live replacement.
