Product Details

Modicon 7628-000249627 is a precision industrial circuit assembly board and reliable signal conditioning board for legacy Modicon automation racks. This replacement control board undertakes signal filtering, level conversion and handshake signal routing between the PLC main controller and peripheral I/O modules. It cleans noisy analog and digital signals from field wiring, stabilizes signal transmission and prevents transient interference from damaging core rack components. Built with multi-layer industrial PCB and conformal coating, this circuit assembly board can sustain continuous operation in harsh factory environments with vibration, dust and fluctuating temperature. As a discontinued legacy spare, this signal conditioning board serves as a drop-in replacement for failed internal circuit assemblies, helping ageing control racks restore stable internal signal transmission without redesigning the whole control system.

Supported Functions

This industrial circuit assembly board supports signal conditioning, noise filtering and signal level shifting. The signal conditioning board routes handshake and status feedback signals between rack modules, isolates local circuit faults and assists fault signal collection. This replacement control board stabilizes weak field signals before forwarding them to the main CPU, supports continuous signal transmission during long runtime, and simplifies troubleshooting by separating signal paths inside the rack.

Core Functions

As an essential signal conditioning board, this industrial circuit assembly board maintains clean signal channels between the PLC backplane and peripheral modules, suppressing common-mode noise and voltage spikes. It acts as an intermediate signal buffer to improve the integrity of field acquisition and output signals. This replacement control board serves as a direct spare to recover stable internal signal routing for ageing Modicon automation racks.
