Schneider ASBFRQ254 I/O Module | 8 Inputs 6 Outputs 24V DC

The ASBFRQ254 functions as a digital input and output module for Schneider systems. This unit reads sensor signals and controls actuators in automation networks. Its rectangular frame measures 118 millimeters in width. The module height reaches 112 millimeters exactly. Depth stays at 85 millimeters. You will find this unit weighs approximately 0.45 kilograms. Therefore, installation requires only a standard DIN rail clip. Two 10-position removable terminal blocks handle all field wiring connections.

Physical Layout and Connectors

Each terminal block accepts wires up to 16 AWG gauge. A green LED indicates power present on the module. Individual LEDs show status for each input and output channel. Four mounting tabs secure the unit to TS35 DIN rails. You can remove each terminal block independently for maintenance access.

Internal Design and Energy Storage

The ASBFRQ254 contains exactly 178 discrete components onboard. A 470 microfarad capacitor bank filters the internal logic supply voltage. Eight optocouplers provide isolation for every input channel. Six power MOSFETs handle the output switching duties. Each MOSFET includes built-in overcurrent and thermal protection. The module also stores configuration data in onboard non-volatile memory.

Operational Performance

This I/O module reads eight digital inputs from pushbuttons or proximity sensors. It switches six transistor outputs to control LEDs or small solenoids. Moreover, the unit responds to input changes within 1 millisecond. You can connect 24V DC sourcing outputs to relay coils directly. The module filters electrical noise with built-in debounce circuitry. Fourteen LEDs show real-time input and output status across the front panel. Consequently, you achieve reliable mixed I/O control for compact machines. Schneider designed this module for AS-B series automation platforms. Its conformal coating protects against humidity and light contamination.

In summary, the ASBFRQ254 delivers flexible digital I/O capability. Use this module for conveyor control or packaging equipment. It saves panel space with 14 total points in one unit. Order this I/O module for your Schneider automation system upgrade.
