Specifications

Table: DO 8-channel 120/230 VAC isolated card specifications
Item Specification
Number of channels Eight
Off state leakage
  • 2 mA maximum at 120 VAC
  • 4 mA maximum at 230 VAC
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
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 re-configured as a latched output.
LocalBus current (12 VDC nominal), per card
  • 100 mA typical
  • 150 mA maximum
Field circuit power, per card None
Isolation Each channel is optically isolated from the system at 250 VAC and from other channels at 250 VAC.
Heat dissipation 5.4 W
Optional fuse 2.0 A (inrush 5A for <10 ms at 0.1% duty cycle)
Mounting Assigned slot of I/O carrier
