Schneider Electric VW3A66201T IO Extension Module

The Schneider Electric VW3A66201T IO Extension Module adds four 24 VDC logic inputs, two differential analog inputs, two normally open relay outputs, and a 0–20 mA analog output to Altivar 66 AC variable frequency drives, all powered from 24 VDC and mounted inside the drive assembly. It also provides a PCMCIA slot for optional communication cards, enabling expanded drive communication alongside I/O expansion. This Telemecanique module is designed to extend the control and monitoring capabilities of compatible Altivar 66 drives, improving machine integration and process diagnostics in industrial motor control and automation systems. Widely used in conveyor systems, pumps, fans, compressors, and material handling equipment, the VW3A66201T supports LI5–LI8 digital inputs, two differential analog inputs, two NO relay outputs, and a single analog output to meet diverse control and sensing needs.
