Product Description

The Schneider Electric DAP 208 is a high-performance digital output module designed for the Modicon 800 Series I/O platform. This module features 8 independent electromechanical relay outputs, providing robust electrical isolation between the control system backplane and field-level load circuits. It is engineered for demanding industrial environments, including petrochemical refineries, power generation, and mineral processing, where reliable switching of AC or DC loads is critical for process stability.

Features

• Channel Density: 8 independent, normally open (NO) relay channels.
• Galvanic Isolation: High-dielectric barrier design ensures complete separation between field loads and the internal backplane data bus.
• Integrated Protection: On-board snubber networks mitigate contact degradation from inductive back-EMF during high-frequency switching cycles.
• Diagnostic Feedback: Front-panel LED indicators provide real-time status monitoring for each output channel, simplifying field troubleshooting.
• Flexible Load Handling: Supports a broad range of operating voltages, suitable for both AC and DC control applications.

Installation Guidelines

• Ensure the system power is completely disconnected before inserting or removing the module from the I/O backplane to prevent electrical arcing.
• Verify that all field wiring is properly routed through the removable screw terminal block to maintain clean signal separation.
• Maintain adequate ventilation within the cabinet to ensure the ambient temperature remains within the specified 0 to 60 deg C range.
• Practice standard ESD (Electrostatic Discharge) handling procedures when touching the module circuitry to prevent internal component damage.
• Ensure that cumulative current across all channels does not exceed the 12.0 A module limit during peak operational demand.

FAQ

What is the primary function of the DAP 208 module?
The DAP 208 is a relay output module designed to bridge low-voltage control signals from the Modicon 800 Series backplane to higher-voltage external field devices.

Are the output channels isolated?
Yes, the module provides galvanic isolation between the output channels and the system bus, protecting the controller from external surges and short-circuits.

Can this module handle inductive loads?
Yes, each channel is equipped with localized snubber networks designed to suppress inductive counter-electromotive force, which helps extend the operational life of the relay contacts.
