ICS Triplex (Rockwell Automation) T8225
The Trusted® power supply assembly converts redundant main line voltages of either 110 Vac / 240
Vac or 24 Vdc, to +15 Vdc or +24 Vdc output power for system and field power requirements.
-Redundant power inputs.
• 250 W.
• Hot replaceable.
• Current sharing.
• Power factor correction.
• Front panel indicators for input, output voltage status and output current level on each module.
• External status signals.
• TϋV Certified IEC 61508 SIL 3.

ICS Triplex Digital DC input modules provide input detection for 16 fields input switches There are three types of modules available for Interface to inputs fed from a 24, 48 or 120 VDC field power supplies The tripled I / O security bus of each module The interface ensures that no module failure can affect Regent system operation or other I / O modules in the system. Extensive fault detection and criticism announcement redundant circuits help prevent controllers from receiving erroneous data of a faulty input module.

Three DC digital input modules can be connected in parallel to obtain fault tolerant input sensing. In this triple module configuration, a failed module can be removed and replaced without interrupting the input signals.
