TRICONEX 3515

  • Pulse Signal Conditioning: It receives pulse signals from external sensors like flow meters or encoders. These signals might be voltage pulses or contact closures.
  • Optical Isolation: The 3515 often uses optical isolation to electrically isolate the process sensor circuit from the internal SIS circuitry. This isolation helps prevent electrical noise or ground faults from affecting the integrity of the safety logic execution.
  • Pulse Counting and Totalization: The module accurately counts the received pulses and accumulates the total pulse count over time. This total count can represent a process variable like flow rate or total rotations.
  • Data Transmission: The 3515 transmits the accumulated pulse count data to the SIS processor module through the Triconex communication network for further processing and safety logic evaluation.

Product Parameters and Specifications (Refer to Schneider Electric website or datasheet for details):

Exact specifications will vary depending on the specific revision of the TRICONEX 3515 module. However, some typical parameters to look for include:

  • Input Type: The type of pulse signal the module can accept (e.g., voltage pulse, contact closure).
  • Pulse Frequency Range: The minimum and maximum pulse frequency the module can accurately count.
  • Pulse Width: The minimum pulse width required for reliable detection.
  • Input Filtering: Configurability of filtering options to minimize the impact of electrical noise on pulse counting.
  • Output Resolution: The resolution of the total pulse count data transmitted to the processor (e.g., 32-bit integer).

Description

The TRICONEX 3515 is a Pulse Input (PI) module manufactured by Invensys (now Schneider Electric) for use within the Triconex safety instrumented system (SIS). Here’s a breakdown of the product details based on information from various sources:

Product Name:

  • Invensys Triconex 3515 Pulse Input (PI) Module

Product Description:

The TRICONEX 3515 is used within a Triconex SIS to count and totalize pulses received from external sensors. These pulses can represent various process parameters like flow rate, speed, or rotation count. The PI module converts the pulse information into digital data for the SIS processor module to monitor and analyze process conditions.

Product Function:

The TRICONEX 3515 performs the following tasks within an SIS:

  • Pulse Signal Conditioning: It receives pulse signals from external sensors like flow meters or encoders. These signals might be voltage pulses or contact closures.
  • Optical Isolation: The 3515 often uses optical isolation to electrically isolate the process sensor circuit from the internal SIS circuitry. This isolation helps prevent electrical noise or ground faults from affecting the integrity of the safety logic execution.
  • Pulse Counting and Totalization: The module accurately counts the received pulses and accumulates the total pulse count over time. This total count can represent a process variable like flow rate or total rotations.
  • Data Transmission: The 3515 transmits the accumulated pulse count data to the SIS processor module through the Triconex communication network for further processing and safety logic evaluation.
