Backplane Bus Communication Velocity & I/O Density Scaling
The module delivers 16-channel I/O density scaling inside a single subrack footprint to drive current loops for variable speed drives, control valves, and process positioners. Utilizing a 16-bit digital-to-analog converter, each output channel updates at up to 100 samples/second while maintaining an accuracy of +/-0.05% of full scale across 0-20 mA and 4-20 mA ranges. High backplane bus communication velocity allows simultaneous field updating without internal frame buffering delays. Firmware flash compatibility across system revisions guarantees deterministic execution and channel-to-channel signal isolation under IP20 operational environments.
Frequently Asked Questions
Q: What current output ranges are selectable on the 1MRK002305-AAr01 channels?
A: Each of the 16 isolated output channels supports software-configurable current ranges of 0-20 mA and 4-20 mA with 16-bit signal resolution.
Q: What is the maximum update speed per output channel on this module?
A: The internal processing engine executes signal conversions at a rate of up to 100 samples/second per channel.
Field Installation Guidelines
- Verify that the external 24 VDC power supply feed is de-energized prior to inserting or removing the card from the chassis slot.
- Use twisted-pair shielded instrumentation cables for all 4-20 mA signal runs to minimize inductive noise pickup.
- Connect cable shield drain wires to a dedicated cabinet grounding bar at one end only to prevent ground loop currents.
- Ensure cabinet enclosure ventilation maintains ambient operating temperatures between -20 and +60 deg C to preserve +/-0.05% full-scale accuracy.
