2.Main functions and uses

Support Ethernet supply main chassis:TRICONEX 3721 communication module is able to support Ethernet-connected main chassis,accommodating main processors,memory backup batteries,communication modules,and I/O modules.

Extension chassis connection:The module supports the connection of additional I/O modules no more than 100 feet(about 30 meters)from the main chassis,and even supports operations up to 1000 feet(about 300 meters)in restricted applications.In addition,RXM chassis are also supported for connecting I/O modules within 7.5 miles(about 12 kilometers)from the main chassis.

Digital input function:As a digital input card,TRICONEX 3721 provides 16 digital input channels that can be used to monitor various types of digital signals,such as contact closure,voltage signal and current signal.These channels can be configured individually,allowing users to set parameters such as input type,filter,debounce time,etc.

Adaptability to harsh environments:This product is designed for harsh environments and can withstand extreme temperatures,shock and vibration to ensure stable operation under harsh industrial conditions.

III.Technical specifications and parameters

Here are some of the main technical specifications and parameters(may vary depending on the specific model or configuration):
