TRICONEX 3805E highly reliable analog output module

The TRICONEX 3805E is a highly reliable analog output module that is part of the Triconex series Safety Instrumented System (SIS). It is mainly used to convert digital signals into analog signals for driving actuators such as valves, pumps, motors, and other equipment. Below is its comprehensive detailed information:

1. Technical Parameters

Input Voltage: 24V DC
Output Voltage: 5V DC
Operating Temperature Range: -40°C to +70°C or -40°C to +85°C
Resolution: 12-bit
Output Current: 4–20mA, with accuracy less than 0.25% (within the 4–20mA range)
Communication Interfaces: Supports Ethernet/IP, Modbus TCP/IP, Profibus, etc.

2. Product Features

High Reliability: Adopts a Triple Modular Redundancy (TMR) design. Three independent sub-circuits perform control tasks in parallel, and a "voting" mechanism ensures data consistency. It can maintain uninterrupted operation under hardware failures or transient interference, meeting the requirements of Safety Integrity Level (SIL) 3.
High Precision: Boasts an output accuracy of up to ±0.1% and supports 4–20mA current output (with over-range capability up to +6%). Each channel is equipped with a self-calibration function to ensure the stability and accuracy of signal output.
Flexibility: Supports multiple communication protocols and interfaces, such as Modbus, Profibus, and Ethernet, facilitating integration with other devices.
Easy Maintenance: Features a modular design and supports hot-swapping, enabling convenient maintenance and expansion. It also has a diagnostic function that can quickly identify faults and trigger alarms.
