TRICONEX 3502E | High Reliability Triple Redundancy (TMR) Digital Input Module

TRICONEX 3502E is a high reliability Triple Redundancy (TMR) digital input module produced by TRICONEX company.

· Input points: 32 points, every 8 points is a set of common ends.

· Voltage range: AC or DC 35-95VAC/VDC, with a typical operating voltage of 48VAC/VDC.

· Frequency range: DC or 47-63Hz.

· Maximum voltage: 95VAC/VDC.

· Switch level: Turn off to>32VAC/VDC, turn on to<11VAC/VDC.

· Nominal opening current: 6-9mA.

· Typical lag: 7VAC/VDC.

· Input delay: Off to on<8ms, on to off<15ms.

· Point isolation: 1500VDC.

· Nominal input impedance:> 2.9k Ω.

· Maximum on-site power load per point: 1.0 watt per point opened at maximum on-site voltage.

· Safety Instrumented System: In high-risk industries such as chemical, petroleum, and natural gas, it is used to collect digital input signals from on-site equipment, 

such as emergency stop buttons, safety valve status, and combustible gas alarms. Through its TMR structure and self testing function, it ensures accurate and reliable 

operation in the event of any single point of failure, timely transmission of danger signals to the control system, triggering corresponding safety protection measures, 

and ensuring the safety of personnel and equipment.
