TRICONEX 3201 digital input module
The TRICONEX 3201 is a dedicated digital input module belonging to the EcoStruxure Triconex Safety Instrumented System (SIS), designed specifically for reliable collection of discrete digital signals in industrial safety-critical scenarios. It serves as a core "signal entry point" for the Triconex system, ensuring accurate transmission of field switch states to the controller for safety logic judgment and process monitoring. Below is its comprehensive detailed information:
The primary role of the TRICONEX 3201 is to acquire discrete digital signals from on-site devices (such as emergency stop buttons, limit switches, pressure switches, and fire/gas detector alarms) and convert these signals into standardized digital data recognizable by the Triconex controller. It is widely used in safety-critical links that require high reliability, such as:
- Monitoring the on/off status of safety interlock switches (e.g., reactor door closure, valve limit positions).
- Collecting alarm signals from field safety devices (e.g., combustible gas leakage alarms, over-temperature switches).
- Transmitting status signals of emergency control components (e.g., emergency stop button presses, emergency shutdown valve feedback).
- Input Type: Dry contact (normally open/NO, normally closed/NC, software-configurable) and wet contact (active high/low, adaptable to 24V DC field power supplies).
- Nominal Input Voltage: 24V DC (compatible with 18–32V DC wide voltage range to tolerate industrial power fluctuations).
- Input Current: 5–12mA per channel (typical operating current, ensuring stable detection of weak signals without false triggers).
- Response Time: <1ms (fast enough to capture transient signals like emergency stop button presses, avoiding delays in safety actions).
- Leakage Current: <100μA (max, preventing false activation of field devices due to residual current).
The company has multiple main brands, and if you have other brand requirements, you can also send them to customer service for inquiry.
