Technical Specifications and Physical Characteristics

Understanding the exact specifications of the Schneider ASBDEP297 ensures proper integration into your TSX Compact control system. This module features robust optocoupler isolation for each individual input channel.

Input Channel Configuration and Electrical Ratings

The Schneider ASBDEP297 provides multiple input channels for monitoring field devices. Its 48 VDC rating suits industrial applications using standard European control voltages.

• Input Voltage: The module accepts 48 Volts DC nominal input from field sensors. This voltage rating matches many industrial proximity and limit switches.

• Number of Inputs: It contains multiple discrete input channels for versatile connectivity. The exact channel count supports typical TSX Compact I/O requirements.

• Input Current: Each channel draws a specific current at rated input voltage. This ensures compatibility with standard sensor output capabilities.

• Logic Thresholds: The module defines clear ON and OFF state voltage thresholds. Consequently, it provides reliable signal detection despite voltage variations.

• Response Time: Input filtering ensures stable readings in noisy industrial environments. Typical response times suit most machine control applications.

Optocoupler Isolation and Protection Features

The Schneider ASBDEP297 uses optocoupler technology to protect the PLC backplane from field transients. This isolation ensures reliable operation in electrically noisy environments.

• Isolation Voltage: Optocouplers provide galvanic isolation between field and logic sides. Therefore, voltage spikes on field wiring cannot damage the CPU.

• Channel Isolation: Each input channel typically includes independent isolation barriers. This prevents faults on one channel from affecting others.

• Noise Immunity: Optical coupling rejects common-mode noise from field wiring. Consequently, the module reads accurate signals despite electrical interference.

• Transient Protection: Internal clamping circuits absorb voltage spikes from inductive loads. This extends module life in applications with solenoids or contactors.

• Dielectric Strength: The isolation barrier withstands high voltage during dielectric testing. This ensures safety compliance with industrial standards.

Power Requirements and Backplane Interface

The Schneider ASBDEP297 draws power from the TSX Compact backplane for its internal circuits. Its efficient design minimizes load on the system power supply.

• Backplane Current: The module consumes a specific current from the +5 VDC supply. Therefore, verify adequate power budget before installation.

• Field Power: Input circuits derive power from the external 48 VDC source. The module does not provide power to field devices.

• Indicator LEDs: Front-panel LEDs show the status of each individual input channel. This simplifies troubleshooting during machine operation.

• Connector Type: The front panel includes a removable terminal block for field wiring. Consequently, you can replace the module without rewiring.

• Keying: Mechanical keying prevents insertion of incompatible modules into the slot. This protects both the module and the backplane from damage.

Wiring Specifications and Connection Details

The Schneider ASBDEP297 accepts standard industrial wiring for field device connections. Its terminal design accommodates various wire sizes for installation flexibility.

• Wire Size: You can use solid or stranded copper wire from AWG #14 to AWG #22. This range suits most panel wiring practices.

• Terminal Type: Screw-type terminals provide secure connections resistant to vibration. Therefore, they maintain contact in high-vibration environments.

• Wire Strip Length: Proper strip length ensures full contact without exposed conductors. Follow standard panel wiring practices for reliable connections.

• Torque Specification: Terminals require specific tightening torque for optimal connection. This prevents loose connections from heating or arcing.

• Ferrule Use: You may use wire ferrules for stranded wire termination. This prevents strand fraying and ensures reliable terminal contact.

Environmental Specifications and Operating Conditions

The Schneider ASBDEP297 operates reliably across a wide range of environmental conditions. Its robust design suits demanding industrial automation applications.

• Operating Temperature: The module functions from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). This range accommodates most industrial control cabinet environments.

• Storage Temperature: It withstands storage from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). This tolerance ensures survival during shipping and warehouse storage.

• Humidity Rating: The module operates at 5% to 95% relative humidity without condensation. Conformal coating protects components from moisture damage.

• Vibration Resistance: It withstands standard industrial vibration levels during operation. This ensures reliable performance near rotating machinery.

• Shock Resistance: The module tolerates typical industrial shock during operation and handling. This protects against damage during installation and maintenance.

System Integration and Applications

Integrating the Schneider ASBDEP297 into your TSX Compact system requires straightforward installation. It works alongside other modules in broader Schneider Electric automation architectures.

• Rack Compatibility: The module fits any TSX Compact rack with available I/O slots. It occupies a single slot position in the chassis.

• CPU Compatibility: It works with all TSX Compact series CPU processors. Therefore, you can use it in both new and existing systems.

• Programming: You configure input channels through the TSX Compact programming software. This assigns addresses and sets filtering parameters.

• Diagnostics: The module reports certain fault conditions to the CPU. This enables rapid troubleshooting of field wiring problems.

• Spare Parts: The Schneider ASBDEP297 remains available as a replacement part. We stock this module to support your ongoing maintenance needs.
