MPN: A68AD — industrial control spare part, in stock at TGK Parts.
The A68AD is the 8-channel analog input module of the Mitsubishi MELSEC-A series, converting voltage and current signals from sensors, transducers and temperature instruments into digital values for the A-series CPU. Analog modules age hardest of all A-series cards — offset drift and reference failures are common after decades of service.
Every A68AD we ship is verified on all 8 channels with measured conversion values; calibration drift is documented in the test report.

Replacement and spare part for industrial automation equipment — production lines, CNC machines, packaging machinery, textile machinery, printing equipment and more.
A-series slots accept same-family modules; cross-generation replacement needs wiring and config review.
Each channel is exercised at known signal levels and measured against reference values.
We test with standard signal sources; field verification with your sensor is recommended at commissioning.
