The D4-08NA is an 8-point discrete input module for Automation Direct's DirectLOGIC DL405 PLCs, designed to accept 120–240 VAC input signals. It provides two isolated common terminals, four inputs per common, and includes a removable terminal block for straightforward field wiring. As part of the DL405 AC I/O family, it expands the PLC’s ability to read ON/OFF states from AC sensors and devices such as motor starters, relays, and pumps. The D4-08NA is an AC input module with eight channels that integrate into the DL405 platform to support reliable sensing of discrete control signals in industrial environments.
