MPN: AT-23000
AT-23000 – 4 Digital Input Module with TCP/IP
The AT-23000 is a compact and efficient 4-channel Digital Input Module designed for reliable signal monitoring and control over TCP/IP networks. It enables seamless integration of field devices such as sensors, switches, and push buttons into Ethernet-based automation and monitoring systems.
Featuring sinking-type inputs with logic level detection (≥6V for Logic 1, ≤5V for Logic 0), the AT-23000 ensures accurate and stable signal acquisition. Its web-based configuration tool simplifies setup and diagnostics, while the built-in watchdog timer provides enhanced system reliability.
Designed for industrial environments, the AT-23000 offers wide operating voltage (9–36 VDC) and low power consumption, making it an ideal solution for remote I/O applications and distributed control systems.
