The Triconex 3721 product family includes a range of modules. This section includes: a summary of system components and their uses, a table listing standard products and their models, and a specification summary for each standard product in the Tricon family. For complete information, see the Tricon Planning and Installation Guide.

Triconex 3721 chassis

? The main box houses the main processor, memory backup battery, communication module, and I/O module.

Expansion chassis for other I/O modules not more than 100 feet (30 meters) from the main chassis. In restricted applications, operations up to 1,000 feet (300 m) are supported.

RXM chassis for I/O modules not more than 7.5 miles (12 km) from the main chassis.

? Mechanical Keying Each slot in Tricon is mechanically keyed to a specific type of module. This prevents the module from being installed in an inappropriate slot.

Optical Fiber Remote Expansion Module (RXM)

For operation of the extension chassis at a distance of 7.5 miles (12 km) from the main chassis, with special immunity to electrostatic and electromagnetic interference.

Triconex 3721 I/O Module ? Digital input module

Receive discrete signals at these nominal voltages: 115 VAC/VDC, 48 VAC/VDC, and 24 VAC/VDC. All voltages are available in the TMR module. Non-tmr modules offer only 24 VDC and 48 VDC voltages. Speed input and accumulation modules are also available.

Monitor digital output modules that produce discrete output signals at these nominal voltages, with diagnostic ranges for field circuits and load devices: 115 VAC, 120 VDC, 48 VDC, and 24 VDC.

Digital output modules generate discrete output signals at these nominal voltages: 115 VAC, 120 VDC, 24 and 48 VDC. Dual output modules are also available.

? Analog input modules receive the following types of analog signals: 0-5 VDC, -5 to +5 VDC, 0-10 VDC, and type J, K, T, and E thermocouples. There are isolated and DCcoupled versions.

? The analog output module drives eight 4-20 mA analog output signals. The high-current AO module consists of 6 points from 4-20 mA and 2 points from 20-320 mA.

Control pulse input: The TRICONEX 3721 module supports the input of control pulse signals and can receive pulse signals sent by external devices for triggering or controlling related operations. It has high precision and stability to meet the needs of precise control.

Control pulse output: The module also provides the output function of control pulse signal, which can send pulse signal to other devices or systems through the output port. These output signals can be used for synchronous operation, timing control, or other applications that require pulse triggering.

Multi-channel support: The TRICONEX 3721 module typically provides multiple independent channels, each of which can be configured and controlled individually. This enables it to handle multiple different control pulse input and output tasks simultaneously, increasing the flexibility and scalability of the system.

Flexible configuration and management: The module has flexible configuration and management functions. The user can set and monitor the parameters of the module through the configuration tool and interface, including pulse frequency, pulse width, pulse triggering conditions, etc. In this way, you can customize the configuration and management based on actual requirements.

Reliability and durability: Honeywell is a well-known brand in the field of industrial automation, and its modules are highly reliable and durable. The TRICONEX 3721 module has undergone rigorous quality control and testing to ensure stable operation in harsh industrial environments and a long service life.
