DC Digital Input Modules 24 VDC, 48 VDC and 120 VDC (T3401, T3402 and T3408)

DC digital input modules provide input sensing for 16 field input switches. Three types of modules are available for interfacing to inputs powered from 24, 48, or 120 VDC field power supplies. Each module's triplicated I/O Safetybus interface ensures that no failure in the module can affect the operation of the Regent system or other I/O modules in the system. Extensive fault detection and annunciation of critical redundant circuits help prevent the controllers from receiving erroneous data from a faulty input module.

Features: 

• 40 Triple Modular Redundant (TMR) input channels per module.

• Comprehensive, automatic diagnostics and self-test.

• Selectable line monitoring per channel to detect open circuit and short circuit field wiring

faults.

• 2500 V impulse withstand opto/galvanic isolation barrier. • On-board Sequence of Events (SOE) reporting with 1 ms resolution.

• Configurable 50/60 Hz digital filtering to eliminate field induced noise.

• Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot

(one spare slot for many modules) configurations.
