Kingfisher Plus+ Hardware Manual
All AI-10 modules provide:
• 8 analogue inputs with high electrical isolation between the field terminals and the RTU
logic.
• A 24 V isolated output that can be used to power field sensors / transducers
• 16 bit input resolution
• Full compatibility with the AI-1 and AI-4 analogue input modules but with enhanced
resolution.
The AI-10 supports various current input ranges as follows:
• 0-20 mA
• 4-20 mA
• ±10 mA
1
• ±20 mA

For AI-10 v2.x only unipolar current ranges are recommended for use. Bipolar ranges are
not calibrated for current measurement.
The AI-10-V supports various voltage input ranges as follows:
• 0-5 V
1
• 1-5 V
1
• ±2.5 V
• ±5 V
• ±10 V

For AI-10 v2.x only bipolar voltage ranges are recommended for use. Unipolar ranges are
not calibrated for voltage measurement.
To minimize the capacitive loading and noise, all field connections to the module should be
wired using a good grade of twisted, shielded instrumentation cable. The shields can be
connected to ground.
This module consumes power from the +5 V
DC
and +12 V
DC
RTU rails. A built-in 24V DC-DC
converter is used to provide isolated power to the analogue front-end and can also be
utilised to power the field devices if required.
