TRICONEX I/O Module

TRICONEX I/O Module

DESCRIPTION

The Triconex product family includes a  comprehensive range of modules. This  section includes: a summary of the  system components and their uses, a  table that lists standard products and  their model numbers, and a summary of  specifications for each standard product  in the Tricon family.

Summary of Tricon  Components

Chassis 

• Main Chassis—houses Main  Processors, memory back-up  batteries, communication modules  and I/O modules. 

• Expansion Chassis—for additional  I/O modules up to 100 feet (30  meters) away from the Main  Chassis. In restricted applications,  operation up to 1,000 feet (300  meters) is supported. 

• RXM Chassis—for I/O modules up  to 7.5 miles (12 kilometers) away  from the Main Chassis. 

• Mechanical Keying—Each slot in  the Tricon is mechanically keyed to  correspond with a specific type of  module. This prevents the  installation of modules into  improper slots.

Power Supply Modules 

• Provide logic power to modules in  the Main, Expansion or RXM  Chassis. Available in 24 VDC, 115  VAC and 230 VAC versions. The  power rating of each power supply is  175 watts at 140 ° F (60° C).

Main Processors 

The Main Processors execute the  system diagnostics and the user-written  control program.

Communication Modules 

• Tricon Communication Modules  (TCM) support a number of  Triconex protocols and applications  and user-written applications on  Ethernet (802.3) networks,  including TriStation, Modbus TCP  and OPC. It also supports RS-232  and RS-485 serial communication  with Modbus devices, TriStation  1131, and GPS for time  synchronization. 

• Enhanced Intelligent  Communication Modules (EICM)  support RS-232, RS-422 and RS- 485 serial communication with  Modbus devices and TriStation  1131. 

• Network Communication Modules  (NCM) support a number of  Triconex protocols and applications  and user-written applications on  Ethernet (802.3) networks,  including TriStation 1131. 

• Safety Manager Modules (SMM) act  as an interface between a Tricon  controller and a Honeywell  Universal Control Network (UCN),  one of three principal networks of  the TDC-3000 DCS.

• Hiway Interface Modules (HIM) act  as an interface between a Tricon  controller and a Honeywell  TDC-3000 Hiway Gateway and  Local Control Network (LCN).

Interface Modules 

• HART Analog Input Interface  Modules act as an interface between  4-20 mA analog input points from  HART smart devices in the field and  HART Host software running on a  PC. 

• HART Analog Output Interface  Modules act as an interface between  4-20 mA analog output points from  HART smart devices in the field and  HART Host software running on a  PC.

I/O Modules 

• Digital Input Modules receive  discrete signals of these nominal  voltages: 115 VAC/VDC, 48  VAC/VDC, and 24 VAC/VDC. All  voltages are available in TMR  modules. Non-TMR modules are  available in 24 VDC and 48 VDC  only. Speed input and totalization  modules are also available. 

• Supervised Digital Output Modules  produce discrete output signals of  these nominal voltages, with  diagnostic coverage of the field  circuit and load device: 115 VAC,  120 VDC, 48 VDC, and 24 VDC.
