The IAI Additive Injection Controller is a universally powered (85-265VAC) or 10-40VDC powered injection controller for liquids featuring a 2.8 inch TFT colour LCD display at 320x480 pixels, a M3 32 bit ARM processor and quadrature pulse input for main and additive flow. The IAI Controller combines with an additive injection manifold to provide a compact additive injection system. The system is configured by push buttons on a four-button infrared remote control or RS485 communication from a host.
The controller can operate in:
Injection rate on the main flow throughput and a user programmed algorithm
Permissive Pace Mode
Injection rate on the main flow throughput, a user programmed algorithm and enabled by a permissive input
Inject additive enabled by the squirt button or remotely wired to the permissive input
Start injection from first received main flow pulse and IAI algorithm, and stop at programmed batch size
Algorithm and start signal from communication link
The IAI accepts a dual channel input from 0 to 5KHZ and channel one is DIP switch selectable for open collector, reed, Hall and turbine signals (from 20mV peak to peak)
The IAI incorporates a 480mm wide x 232mm high colour TFT LCD graphics module backlight
Four button IR remote is potted in epoxy and complies with AS/NZS 60079.18: 2005
The IAI has two 4-20mA outputs for controlling two modulating valves or pumps and two pulse inputs from flow meters. Proportional and Integral control is used to control both flow rates either independently or in ratio.
85 to 265VAC 47-63 Hz or DC to DC converter isolator from 10 to 40VDC. An adjustable transducer power supply of 8 to 20VDC at 50mA is incorporated.
