2.Technical specifications
Power supply:Dual power supply redundant input,DC(9-36)V,typical value is DC24V,power consumption is less than 4W.It has DC1500V voltage isolation and reverse connection protection functions,and adopts industrial terminal interface.
Relay alarm output:including optical fiber link failure and power failure alarm output,contact capacity is DC48V/1A,also using industrial terminal interface.
Mechanical characteristics:
Dimensions:132mm×105mm×52mm.
Housing:IP30 protection level,using corrugated aluminum reinforced housing.
Installation method:support 35mm DIN rail installation.
Net weight:800g.
Working environment:
Working temperature:-10-70℃(optional-40~+85℃wide temperature range).
Relative humidity:≤90%(no condensation).
Storage temperature:-40~80℃.
III.Functional features
Triple modular redundancy:three identical sub-circuits independently execute the control program to ensure the highest integrity of the system at all times.
Industrial environment tolerance:can withstand harsh industrial environments and ensure stable operation under harsh conditions.
On-site installation and repair:support on-site installation,module-level installation and repair work can be carried out on-site online without disrupting on-site wiring.
I/O module support:can support up to a certain number of I/O modules(analog and digital)and optional communication modules.Communication modules can be connected to Modbus hosts and slaves,or to distributed control systems(DCS)such as Foxboro,Honeywell,and other Tricon in a Peer-to-Peer network,as well as external hosts on a TCP/IP network.
Remote I/O module support:can support remote I/O modules located within a certain distance from the host rack.
Intelligent functions:intelligent functions are provided in the input and output modules to reduce the workload of the main processor.
Comprehensive online diagnostics:provides comprehensive online diagnostic functions and repair capabilities,and can perform routine maintenance without interrupting process control when the Tricon is operating normally.
