Z-PASS1-RT

IIoT Edge Gateway, Serial Device Server with integrated I/O

Z-PASS1-RT is a state-of-the-art, highly reliable and secure EDGE device designed to manage a virtually unlimited number of client nodes. It features 2 analog inputs and 6 configurable general-purpose digital channels (DI/DO), providing outstanding versatility. With 2 Fast Ethernet ports, 3 serial ports and 1 USB host 2.0 port, Z-PASS1-RT offers a wide range of connectivity options. Z-PASS1-RT supports a broad range of protocols, ensuring full integration with third-party systems and enabling real-time communication.

This advanced gateway is extremely secure, complying with the most stringent cybersecurity standards, including successful penetration testing according to OWASP, NIST 800-115 Risk Analysis and IEC 62443 guidelines. Configuration is intuitive and straightforward through the integrated web server. Z-PASS1-RT is also part of the LET’S platform, meaning it supports Point-To-Point connections for remote assistance or Single LAN connections for remote control, making it a versatile option for multiple industrial applications.
