DeltaV™ LS DO 24 VDC ETA (Energize to Actuate) CHARM

Specs

Device Type
24 VDC Solenoid coils
ON-State Output rating
500 mA continuous @ 24 VDC. The power is derived from power supplied to the CHARMs Smart Logic Solver Carrier
ON-State Current Limit
Output inrush current limited to 580 mA
OFF-State Leakage Current
5 mA maximum with line fault enabled. 300 µA simplex with line fault disabled. 600 µA redundant with line fault disabled.
Line Fault Detection Levels
Guaranteed Short Circuit: <10 Ω Load, Guaranteed Good Status: 56 Ω to 3.5 kΩ Load, Guaranteed Open Circuit: >20 kΩ Load
Line Fault Test Timing
200 µsec
Field Circuit Protection
580 mA Current Limiting Circuit, Field wiring disconnect
Field Power Common Shutoff Signal
Logic low removes field power like in de-energize to trip applications
CHARM Power req.
41 mA max @ 24 VDC
CHARM Heat Dissipation
1.3 W

Features

  • Eliminate marshalling and add I/O anywhere in the plant without affecting control room cabinets
  • No marshalling cabinet or cross-wiring, fewer wires, much less work and fewer contact points for potential failures
