DeltaV™ LS DO 24 VDC Redundant ETA (Energize to Actuate) CHARM
PDP_CHARM_LS-DI-NAMUR_angle
A Redundant, LS (Logic Solver) Digital Output Characterization Module (CHARM) for 24 VDC Solenoid Cells.
DeltaV™ LS DO 24 VDC Redundant 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 1.16 A
OFF-State Leakage Current
5 mA maximum.
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
1.16 A 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.
82 mA max.(109 mA when used with Relay Terminal block) @ 24 VDC
CHARM Heat Dissipation
2.6 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
  • No marshalling cabinet or cross-wiring, fewer wires, much less work and fewer contact points for potential failures
