Interface Specifications > I/O Cards

DO, 8-Channel, 120 VAC/230 VAC, High-Side

The DeltaV system supports the DO, 8-channel, 120/230 VAC, High-Side card and the Series 2 DO, 8-channel, 120/230 VAC, High-Side card in Simplex mode.

Installation Notes

The Fused I/O terminal block is recommended to provide screw terminations for field wiring for the DO, 8-channel, 120/230 VAC, High-Side card and the Series 2 DO, 8-channel, 120/230 VAC, High-Side card in Simplex mode. An optional terminal block is the I/O terminal block.

Item Specification
Number of channels Eight
Isolation Each channel is optically isolated from the system at 250 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 up to 5°C
  • 2.0 A maximum per card up to 60°C
Series 2:
  • 1.0 A continuous per channel (inrush 5 A for < 100 ms; 20 A for < 20 ms)
  • 3.0 A maximum per card
Optional fuse 2.0 A (inrush 5A for <10 ms at 0.1% duty cycle)
Off state leakage 2 mA maximum at 120 VAC, 4 mA maximum at 230 VAC
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
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.
Mounting Assigned slot of I/O carrier
