PLCs, Power Supplies & Others

The Schneider ASB807032 functions as a discrete input module within the 800 Series I/O platform from Schneider Electric. This module monitors 32 AC input signals from field devices in industrial applications. We supply this input module to support your existing 800 Series installations. It accepts 115 VAC signals from pushbuttons, limit switches, and proximity sensors.

Technical Specifications and Physical Characteristics

Understanding the exact specifications of the Schneider ASB807032 ensures proper integration into your 800 Series I/O system. This module features grouped commons with eight inputs per common connection.

Input Channel Configuration and Electrical Ratings

The Schneider ASB807032 provides 32 input channels for monitoring AC field devices. Its 115 VAC rating suits standard North American industrial control voltages.

• Input Voltage: The module accepts 115 Volts AC nominal input from field sensors. This voltage matches standard North American control systems.

• Input Frequency: It operates at 50 or 60 Hz line frequency automatically. Therefore, it works with both common international power standards.

• Input Grouping: The 32 inputs divide into groups of eight with common returns. Consequently, you need only one common connection per eight inputs.

• 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. This provides reliable signal detection despite voltage variations.

Input Circuit Design and Isolation Features

The Schneider ASB807032 uses robust input circuit design for industrial reliability. Its isolation architecture protects the backplane from field transients.

• Input Filtering: Built-in filters reject high-frequency noise from industrial sources. Therefore, the module reads accurate signals despite electrical interference.

• Isolation Voltage: Optical isolation separates field inputs from logic circuits. Consequently, voltage spikes on field wiring cannot damage the CPU.

• Group Isolation: Each group of eight inputs shares common isolation barriers. This provides cost-effective protection while maintaining safety.

• Transient Protection: Internal clamping circuits absorb voltage spikes from AC lines. This extends module life in electrically noisy environments.

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

Terminal Block and Wiring Specifications

The Schneider ASB807032 uses a terminal block for secure field wiring connections. This design simplifies installation and maintenance procedures.

• Connection Type: A removable terminal block accepts field wiring connections. Therefore, you can pre-wire the connector before module installation.

• Wire Size: The terminals accept solid or stranded copper wire appropriately. Standard sizes from AWG #14 to AWG #22 suit panel wiring.

• Terminal Identification: Clearly marked terminals indicate input channel assignments. This reduces wiring errors during installation and troubleshooting.

• Common Connections: Dedicated terminals serve as commons for each input group. Proper wiring ensures correct signal return paths.

• Screw Type: Captive screws ensure reliable connections that resist vibration. They remain with the terminal block for easy handling.

Power Requirements and Backplane Interface

The Schneider ASB807032 draws power from the 800 Series backplane for its internal circuits. Field power comes from the external AC source.

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

• Logic Supply: Internal circuits derive power from the rack backplane only. This isolates logic from field power for safety.

• Field Power: Input circuits derive power from the external 115 VAC source. The module does not provide power to field devices.

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

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

Response Time and Performance Characteristics

The Schneider ASB807032 provides specific response times for AC input monitoring. These characteristics affect application suitability.

• Turn-On Delay: The module requires a minimum ON time for reliable detection. This filters out noise and contact bounce.

• Turn-Off Delay: Similarly, it requires a minimum OFF time for accurate reading. This prevents false triggering from momentary interruptions.

• Input Frequency: The module suits 50 or 60 Hz AC signals only. It does not support DC input applications.

• Response Consistency: All 32 channels provide identical response characteristics. Therefore, your logic timing remains consistent across inputs.

• Filtering Effect: Input filtering may affect high-speed counting applications. Consider this for applications requiring rapid pulse detection.

Environmental Specifications and Operating Conditions

The Schneider ASB807032 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. This range accommodates most industrial control cabinet environments.

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

• Humidity Rating: The module operates at 5% to 95% relative humidity without condensation. Therefore, it resists moisture-related failures.

• 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. This protects against damage during installation and maintenance.

System Integration and Applications

Integrating the Schneider ASB807032 into your 800 Series system requires straightforward installation. It works alongside other modules in broader Schneider Electric automation architectures.

• Rack Compatibility: The module fits any 800 Series I/O rack with available slots. It occupies a single slot position in the chassis.

• CPU Compatibility: It works with various 800 Series processors and adapters. Therefore, you can use it in both local and remote I/O configurations.

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

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

• Spare Parts: The Schneider ASB807032 remains available as a replacement part. We stock this module to support your ongoing maintenance needs.
