The IAI weatherproof is a universally powered (85-265VAC) or 10-40VDC powered injection controller for liquids featuring a 64 x 128 Mono Graphics LCD display, 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 the instrument face, a four-button infrared remote control or RS485 communication from a host.
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
