Triconex 3451 is a relay output module. It has 32 solid-state output points and operates on 24VDC. The 3451 Solid-State Relay Output Module is a non-triplicated module. It is used for non-critical points that are not compatible with high-side solid-state output switches, such as for connection with annunciator panels. It receives output signals from the three channels of the Main Processor (MP). After voting, these signals are used to drive 32 independent relays. Each output is equipped with a loop-back circuit, which is used to independently verify the operation status of the relay switch. Moreover, the module has a continuous diagnostic function to test its own operating condition.
Technical Parameters of 3451 Solid-State Relay Output Module:
Solid-State Relay Output Module (3451): The rated input voltage is ±24V, the operating voltage range is ±30V, the maximum switching voltage is ±33V peak, the maximum switching power is 15W resistive, the maximum off-state leakage is <100µA, the maximum nominal current is 0.5A per channel, the maximum overcurrent is 0.7A per channel, the voltage drop at the baseplate is <0.25V @ 0.5A. Each output is equipped with a 0.75A fast-acting fuse. The isolation voltage between the functional earth and the protective earth is at least 500V DC, and the isolation voltage between the functional earth and the logic ground is at least 800V DC.
Characteristics of the 3451 Solid-State Relay Output Module:
It drives the relays by receiving signals from the three channels of the MP and performing a voting process. The loop-back circuit can verify the operation of the relays independently of the load. Continuous diagnostics ensure the monitoring of the module's status. The mechanical key design prevents incorrect installation. It supports hot swapping to ensure online maintenance and backup.
The Triconex 3451 Solid - State Relay Output Module belongs to the Triconex Safety Instrumented System (SIS).Application industries:
Oil and Gas Industry: In processes such as oil extraction, oil refining, and natural gas processing, it is used to control the operation of key equipment, ensure the safety of the production process, and prevent accidents such as leaks and explosions.
Chemical Industry: In chemical production, it monitors and controls various chemical reaction processes to ensure the stability and safety of the production process and avoid accidents such as hazardous chemical leaks.
Power Industry: In power generation, transmission, and distribution processes, it is used to protect power equipment, prevent power outages or equipment damage caused by faults, and ensure the reliable operation of the power system.
The Triconex 3451 Solid-State Relay Output Module is usually used in conjunction with main processor modules such as the 3101 MP Module, I/O extender modules like the2281, 2291, and 2292 I/O Extender Module Kits, and communication modules such as the 3201 Communication Module. Among them, the 3101 MP Module is responsible for operations such as executing control applications and providing signals to the 3451 module. The I/O extender modules are used to expand the TMR I/O bus to support more input and output points, and the 3201 Communication Module helps the 3451 module communicate with external devices to achieve remote monitoring and control functions.
