Triconex 3504E High Density Digital Input Module

Number of points: 64 digital inputs

Voltage range: supports 24 VDC or 48 VDC

Signal type: compatible with discrete signal inputs such as proximity switches, limit switches, and pressure sensors

Isolation characteristics: no channel-to-channel isolation

Self-diagnosis function: supports circuit card on/off self-test, and can detect abnormal input signal status

Safety level: SIL 3 certified (compliant with IEC 61508 standard)

Redundant design: TMR architecture ensures that single-point failure does not affect system operation, and the main processor adopts a three-out-of-two voting mechanism

TMR architecture: Three independent channels process signals in parallel to ensure data integrity and system fault tolerance. Triconex 3504E supports online module replacement and hot standby functions

Continuous diagnosis: Triconex 3504E monitors faults in real time for each channel, and the fault indicator locates the specific channel to avoid accidental shutdown

SIL 3 certification: Triconex 3504E meets high safety integrity requirements and is suitable for critical applications such as emergency shutdown (ESD) and fire and gas (F&G)

Fail-safe mechanism: Triconex 3504E supports power-off tripping logic to ensure that the system enters a safe state in the event of a fault

Hot standby support: Triconex 3504E can be configured with hot standby modules to ensure uninterrupted operation of the system

Remote I/O compatibility: Triconex 3504E supports remote rack expansion, up to 12 kilometers (expansion card required)

Anti-interference ability: Triconex 3504E passes electromagnetic compatibility (EMC) Modular structure: Triconex 3504E supports on-site online maintenance to reduce downtime

Emergency shutdown (ESD), wellhead safety control, pipeline leakage protection

Triconex 3636R advantages: triple redundant (TMR) architecture, resistant to harsh environments (-40℃~75℃), in compliance with API safety standards.
