Schneider ASB807132 Input Module

The ASB807132 reads digital signals from field sensors and switches. This module transfers input status to the PLC processor for logic execution. Its rectangular frame measures 112 millimeters in width. The module height reaches 100 millimeters exactly. Depth stays at 78 millimeters. You will find this unit weighs approximately 0.41 kilograms. Therefore, installation requires only a standard DIN rail clip. One 18-position removable terminal block handles all field wiring connections.

Physical Layout and Connectors

The terminal block accepts wires up to 16 AWG gauge. A green LED indicates power present on the module. Individual red LEDs show status for each input channel. Four mounting tabs secure the unit to TS35 DIN rails. You can remove the terminal block without disconnecting the module from the rack.

Internal Design and Energy Storage

The ASB807132 contains exactly 142 discrete components onboard. A 330 microfarad capacitor bank filters the internal logic supply voltage. Sixteen optocouplers provide complete isolation for every input channel. Each optocoupler withstands 1500 volts between field and logic sides. A shift register chip serializes the input data for backplane transmission. The module also includes LED drivers for the 16 status indicators.

Operational Performance

This input module connects directly to pushbuttons, limit switches, and proximity sensors. It accepts input voltages from 19.2 to 30 volts DC. Moreover, the module filters electrical noise with built-in debounce circuitry. You can mix 24V DC sinking sensors from different manufacturers without issues. The unit reports input state changes to the processor every scan cycle. Sixteen red LEDs show real-time input status across the front panel. Consequently, you achieve reliable signal acquisition for medium-sized machines. Schneider designed this module for AS-B series automation platforms. Its conformal coating protects against humidity and light contamination.

In summary, the ASB807132 delivers dependable digital input functionality. Use this module for factory automation or conveyor systems. It provides 16 input points in a compact single-slot design. Order this input module for your Schneider PLC expansion project.
