TRICONEX HCU3700 High-Performance Control Module

Technical Specifications:

• It is designed for high availability and fault tolerance, ensuring continuous operation even in the event of hardware failures.
• The system supports safety integrity levels up to SIL 3 according to IEC 61508, making it suitable for critical safety applications.
• It operates with a triple modular redundant (TMR) architecture where three independent systems process data simultaneously and compare results to ensure accuracy and reliability.

• Output and Signal Parameters
  • The nominal output voltage is 24V DC, and the operating voltage range is 15 - 30V DC, with an absolute maximum output voltage of 33V DC and an absolute maximum reverse input voltage of -0.6V DC.
  • In switching mode, the maximum output current is less than 4.8A with self-limiting function, and the typical value is 3A; in carry mode, the minimum output current is more than 0.7A with self-limiting function, and the typical value is 1.5A.
  • The loop-back threshold is 0 - 5V DC for the off state, 6 - 14V DC for the transition state, and 15 - 30V DC for the on state, and the off-state leakage current to the load is less than 1mA.
• Power and Isolation Parameters
  • The minimum isolation voltage between functional circuit and protective ground is 500V DC, and the minimum isolation voltage between functional circuit and functional logic ground is 800V DC, which can effectively prevent electrical interference from affecting the normal operation of the module.
  • The voltage drop in the on-state is less than 1V DC when the current is 1.5A, which reduces the energy loss during signal transmission and ensures the efficiency of power utilization.

• Input and Signal Parameters
  • It is equipped with 8 independent non-common-ground input channels. The typical input voltage is 24 VDC, and the typical input current per channel is 10 mA.
  • The input signal frequency range is 1 Hz to 100 kHz, and the precision reaches ±0.01% when measuring frequencies between 1000 Hz and 20000 Hz.
  • It has a 16-bit resolution and a pulse counting resolution of 1 microsecond, and the pulse width resolution ranges from 100 microseconds to 10 milliseconds, which can capture pulse signal changes accurately.
• Power and Physical Parameters
  • It relies on 24 VDC power supply to operate stably, matching the power supply configuration of most industrial control systems.
  • There are differences in dimension and weight data from different sources. One source states its dimensions as 80mm x 110mm x 40mm and weight of approximately 200 grams, while another source records dimensions as 120mm x 80mm x 30mm and weight of about 3.3 kilograms, which may be due to whether the measurement includes accessories.

• Electrical Parameters
  • It is configured with 32 commoned digital output channels, the nominal output voltage is 24 VDC, and the adaptive voltage range is 16 - 32 VDC, with a maximum withstand voltage of 36 VDC.
  • Each output channel can provide a maximum current of 1.7 A, the overall power consumption of the module is less than 13 watts, and some data shows that its output power can reach 15 watts.
  • It adopts a dual-power design, which further improves the stability of power supply and avoids system operation interruption caused by single power failure.
• Processing and Memory Parameters
  • It is equipped with a dual-core PowerPC processor with a clock frequency of 800 MHz, which can efficiently support complex control algorithms and logic operations.
  • The module provides a memory range of 1 GB - 8 GB, which can store a large number of control logic programs and real-time operating data to meet the needs of complex industrial control scenarios.
