DI3301 Invensys Triconex Digital Input Module

Product Details:

Description:

Each TMR Digital Input Module has three isolated sets of electronics, called channels, which independently process field data to the module. Each channel places the processed data in an array and transmits this array, on request, to the MP associated with that channel. The MPs vote on the data before passing it to the application. DI Modules include complete, ongoing diagnostics for each channel. If the diagnostics detect a failure on any channel, the Fault indicator turns on and activates the system alarm. The Fault indicator identifies a channel fault, not a complete module failure. The DI Module continuously verifies the ability of the system to detect transitions to the opposite state. DI Modules are guaranteed to operate properly in the presence of a single fault and may continue to operate properly with multiple faults. DI Modules support a hot-spare module. Each DI Module is mechanically keyed to prevent improper installation in a configured baseplate. The Model 3301 DI Module can be used with these baseplates: • Model 2301, which is used with typical applications. • DI External Termination Baseplate, which is used with the Solid State Relay Input External Termination Panel in high-voltage applications, or the Model 9573-610 DI Hazardous Location External Termination Panel.
