Product Introduction

technical parameter
Input points: 32 points.
Nominal input voltage: 24V DC.
Working voltage range: 15-30V DC.
Absolute maximum input voltage: 33V DC.
Absolute maximum reverse input voltage:- 0.6V DC.
Input delay:< 10ms, turn on/off or turn off to turn on time tc=6.4ms, at 25Hz -3dB.
Input impedance:>30k Ω without substrate, ≈ 3k Ω with substrate.
Input power: 0.2W/point at 24V DC and 0.5W/point at 33V DC.
Input threshold: 0-5V DC is the off region, 6-14V DC is the transition region, 15-30V DC is the on region.
Diagnosis: It has forced assignment diagnosis (FVD), with a maximum of<2ms per test. To maintain diagnostic fault coverage, the maximum input flip rate is<20 timescond, and the duration of FVD off state glitches is<2ms, with an amplitude of ≈ 36%.
Output impedance: When 0-5V DC, ≈ 100k Ω.
ADC scan time: All 32 points<1ms.
Functional and protective isolation: minimum 500V DC.
Functional and logical isolation: minimum 800V DC.


Functional Features
Redundancy Design: Compatible with the Triple Redundancy (TMR) structure of the Triconex system, each TMR digital input module has three independent electronic device channels that can independently process the module's on-site data.
High Security: Compliant with SIL3 safety standards, suitable for high-risk industrial control scenarios.
Hot swappable function: Supports hot swappable for easy expansion and maintenance, reducing system downtime.
Fault diagnosis: With comprehensive diagnostic functions, it can detect faults in the module itself and connecting lines, and transmit fault information to the main processor through the diagnostic bus.


application area
Safety Instrumented System (SIS): receives safety critical digital input signals and triggers safety control measures.
Process control: Receive status signals from process sensors, such as pressure, temperature, liquid level switches, etc., to provide on-site equipment status information for the control system.
Emergency Shutdown System (ESD): detects changes in the status of external equipment, triggers emergency shutdown operations, and ensures the safety of personnel and equipment.
