【英文介绍】
3721 is a communication module for industrial automation and process control.
It is mainly used to support the Ethernet supply main case, housing the main processor, memory backup battery, communication module and I/O
module. It can also support an extension chassis for connecting additional I/O modules up to 100 feet (about 30 meters) from the main chassis.
In restricted applications, operations up to 1,000 feet (about 300 meters) are supported.
The design feature of the 3721 communication module is that each slot is mechanically keyed to ensure the correct response to a particular type
of module. It also has high reliability, using high-quality electronic components and materials, and undergoing strict quality control and testing to
ensure long-term stable operation during use.
There are also other derivatives of the 3721, such as the 3721 digital input card and the 3721 control pulse card module. Each of these derivative
products has its own unique features and features to meet different industrial automation and control needs.
