TRICONEX 3721
The TRICONEX 3721 module is an analog input module manufactured by Triconex Corporation (now acquired by Honeywell) for use in Safety instrumentation systems (SIS) **. It is an important part of the Triconex safety instrumentation system, which is responsible for collecting analog signals (such as temperature, pressure, flow, etc.) from field equipment and converting these signals into digital signals for the system to process and analyze.
Product characteristics
High reliability: Triple module redundancy (TMR) technology ensures the safety and availability of the system.
High precision: has a high measurement accuracy, can accurately collect the field signal.
Multiple input ranges: Support a variety of analog input ranges to adapt to different measurement needs.
Comply with safety standards: comply with IEC 61508 and other international safety standards, suitable for high-risk industries.
Product parameters (typical values, specific parameters please refer to the product manual)
Input type: Analog input (voltage or current)
Number of input channels: varies according to the model
Input range: 4-20mA, 0-5V, -5V~+5V, etc
Accuracy: 0.1% FS

Supply voltage: AC 100-240V, 50/60Hz
Product description
The 3721 module serves as the front end of the Triconex safety instrumentation system and is responsible for digitizing the analog signal and transmitting it to the system controller. This data will be used to monitor process variables, detect anomalies, and trigger appropriate safety interlocking actions.
