16-point digital input expansion module compatible with Delta DVP PLC, supports DC signal input, expands switch signal collection points for automation control cabinets, widely used in machinery and production line control

Product Overview

• PN: XI16E1
• Brand: Delta
• Series: DVP PLC Expansion Module
• Type: 16-channel Digital Input Extension Module

• Function: External expansion unit for Delta DVP series programmable logic controllers. It expands 16 independent digital input channels to collect contact signals from proximity switches, limit switches, photoelectric sensors, buttons and relays, transmits switch status to the main PLC host, realizing multi-point field signal acquisition without replacing the main controller.
