System compatibility

JANCD-1020 belongs to Yaskawa Yasnac MX3 CNC controller family,matched with Yasnac MX3 old CNC systems. Widely used in vintage CNC lathes and machining centers. This is a discontinued legacy I/O interface board for old machine tool maintenance spare replacement.

Function

JANCD-1020 serves as high precision CNC I/O interface board. It collects digital signals from limit switches,door interlock and other machine peripheral sensors,outputs switching signals to relays,valves and auxiliary actuators. It converts signal levels between CNC mainboard and machine field components. Built-in opto-coupler isolation and surge protection circuit to suppress workshop interference. It handles machine auxiliary logic and safety interlock signals for Yasnac CNC machine tools.

Installation

Mount JANCD-1020 inside CNC controller cabinet. Complete backplane bus and field wiring according to wiring drawing. Backup CNC parameters before replacement,verify all input and output signal response after power-up.

Interface

‑System backplane bus connector

‑Field I/O terminal block

‑Optocoupler isolation circuit

‑Onboard signal filtering and protection circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Stable signal transmission,strong anti-interference performance for industrial cabinet environment. Standard factory firmware preloaded.

Feature

JANCD-1020 is obsolete Yaskawa Yasnac series spare part. Typical failures include optocoupler burnout,terminal pin oxidation,signal missing. Check board integrity and connector pins before replacement. This board must match corresponding Yasnac MX3 CNC controller,direct substitution without I/O function test is not recommended.

Diagnostic

When input signal loss,output no action or interlock alarm occurs,the board triggers corresponding alarm codes and sends fault signal to CNC main controller.

Built‑in function

Field digital signal acquisition,opto-isolation signal conversion,auxiliary output driving,machine safety interlock processing,I/O fault monitoring,used as Yasnac CNC I/O interface board spare replacement.

Product Brief

JANCD-1020 is Yaskawa Yasnac MX3 CNC series I/O interface board for CNC machine tools and precision automation equipment. Confirm CNC controller model matching before ordering. ESD protection required during handling and installation.
