• Simple touch switch set up with English statement prompts by approved IR remote
  • Low cost – High performance
  • Programmable dual channel quadrature input or single pulse train with DIP switch selection for turbine, reed switch & open collector
  • Background total for main flow and additive flow
  • Dual 4-20mA output with Proportional and Integral algorithm control from the main and additive flow signal for modulating valve control for continuous dispensing of additive
  • Main flow and additive flow rate display
  • Sensor supply that can be adjusted from 8 to 20VDC
  • Micro SD card for 8GB for storage of batching data
  • 85 to 265VAC 47-63 Hz universal supply or factory fitted 10 to 40VDC isolated supply

The controller can operate in:
Pace Mode
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
Slave Mode
Inject additive enabled by the squirt button or remotely wired to the permissive input
Control Mode
Start injection from first received main flow pulse and IAI algorithm, and stop at programmed batch size
Remote mode
Algorithm and start signal from communication link



The IAI accepts a dual channel input from 0 to 2KHZ and is DIP switch selectable for open collector, reed, Hall and turbine signals (from 20mV peak to peak)
