Contrec 214D

Pulse/Frequency Input ATEX Batch Controller

The Model 214D Batch Controller is designed for flow applications where the precise control of batch quantities is required. Batch Total, Accumulated Total and Preset values can all be displayed on the large LCD display.

For hazardous area applications, the 214Di is an intrinsically safe version with both ATEX approval, and CSA approval covering both the USA and Canada.

The 214D has an input conditioning circuit which will accept pulse or frequency flow signals generated by turbine,
positive displacement, paddlewheel or other flowmeters.

Configurable link positions enable the input circuit to be configured for the different signal types.

DC powered with battery backup

The 214D will operate from an external power source between 9 and 28 Volts and draws no more than 4mA.

Lithium batteries provide backup if the DC power is interrupted so that totals are not lost. The solenoids or sensors, however, may still require external power.

Solid state outputs provide control to solenoids and relays, and can sink up to 200mA.
