Specifications

Table: DO 8-channel 120/230 VAC high-side card specifications
Item Specification
Number of channels Eight
Output range 20 VAC to 250 VAC
Output rating
  • 1.0 A continuous per channel (inrush 5 A for < 100 ms; 20 A for < 20 ms)
  • 3.0 A maximum per card
Off state leakage 2 mA maximum at 120 VAC, 4 mA maximum at 230 VAC
Configurable channel types
Discrete output If FAIL_ACTION_MODE is Hold last value (default): Output stays in last state submitted by the controller.
If FAIL_ACTION_MODE is Go to configured failure action mode: Output is driven to the configured faultstate value.
Momentary output If FAIL_ACTION_MODE is Hold last value (default): Output finishes current pulse.
If FAIL_ACTION_MODE is Go to configured failure action mode: Output is driven to the configured faultstate value and the channel is re-configured as a latched output.
Continuous pulse output If FAIL_ACTION_MODE is Hold last value (default): Output continues pulsing.
If FAIL_ACTION_MODE is Go to configured failure action mode: Output is driven to the configured faultstate value and the channel is reconfigured as a latched output.
LocalBus current (12 VDC nominal), per card 100 mA typical 150 mA maximum
Field circuit power, per card 3.0 A at 120 VAC or 230 VAC per I/O Interface
Field power per channel .375 mA at 1 A maximum per channel
Optional fuse 2.0 A (inrush 5A for <10 ms at 0.1% duty cycle)
Heat dissipation 5.4 W
Isolation Each channel is optically isolated from the system at 250 VAC.
Mounting Assigned slot of I/O carrier
