Brand New Invensys Triconex DI3301 DI INPUT MODULE

The Invensys Triconex DI3301 is a digital input (DI) module that is used in safety instrumented systems (SIS). It is designed to interface with field devices such as limit switches, pressure switches, and temperature switches. The DI3301 can also be used to monitor the status of safety valves and other actuators.

The DI3301 is a single-channel DI module that can accommodate up to eight field devices. It has a wide input voltage range of 12 to 36 VDC and can be configured to accept either single-ended or differential inputs. The DI3301 also has a number of features that make it suitable for use in SIS applications, such as:

• Fail-safe design: The DI3301 is designed to fail-safe, meaning that it will always assume a safe state if there is a fault.

• High reliability: The DI3301 is a highly reliable module that is designed to withstand harsh industrial environments.

• Easy to install and maintain: The DI3301 is a plug-and-play module that is easy to install and maintain.

Here are some of the technical specifications of the Invensys Triconex DI3301:

• Input voltage range: 12 to 36 VDC

• Input current range: 2 mA to 20 mA

• Input impedance: 100 kΩ

• Output voltage range: 0 to 5 VDC

• Output current range: 0 to 20 mA

• Output impedance: 100 Ω

• MTBF: 100,000 hours

Description

A controller contains three MPs. Each MP controls a separate channel and operates in parallel with the other two MPs. A dedicated I⁄O control processor on each MP manages the data exchanged between the MP and the I⁄O modules. A triplicated I⁄O bus, located on the baseplates, extends from one column of I⁄O modules to another column of I⁄O modules using I⁄O bus cables. As each input module is polled, the appropriate channel of the I⁄O bus transmits new input data to its MP. The input data is assembled into a table in the MP and is stored in memory for use in the voting process. The individual input table in each MP is transferred to its neighboring MP over the TriBus. After this transfer, voting takes place. The TriBus uses a programmable device with direct memory access to synchronize, transmit, and compare data among the three MPs. If a disagreement occurs, the signal value found in two of three tables prevails, and the third table is corrected accordingly. One-time differences which result from sample timing variations are distinguished from a pattern of differing data. Each MP maintains data about necessary corrections in local memory. Any disparity is flagged and used at the end of the scan by the built-in fault analyzer routines to determine whether a fault exists on a particular module. The MPs send corrected data to the application. The 32-bit MP executes the application in parallel with the neighboring MPs and generates a table of output values that are based on the table of input values according to user-defined rules.The I⁄O control processor on each MP manages the transmission of output data to the output modules by means of the I⁄O bus.
