EC 3-533 is a digital one output pressure controller, designed to work with current output (0-20 mA or 4-20 mA) 2

or 3 wires pressure transducers and it can provide the power-supply to the transducers as long as they are abled to

work inside a range of supply-voltage between 9 an 20 V.

In factory, the instrument gets programmed to accept, at the input, one of the Every Control transducers (EC PRS 00,

EC PRS 01, EC PRS 02 or EC PRS 03) that permit to cover a range of pressure between -0.5 and 250 bar; however, just

changing some parameters it is possible to connect the instrument to other transducers.

The output can be easily programmed to activate at the decrease of pressure (reverse functioning) or to activate at the

increase of pressure (direct functioning).

The SPDT relay output can manage (up to) 8A loads at 230 Vac and are supplied in standard version; as option, it is

possible to request an output with low-voltage signal, suitable to drive the SSR modules (solid state relay).

Besides that, through some parameters programming, it is possible to submit the output activation to a series of delays,

in order to guarantee a proper use of the connected load.

The acoustic alarm, normally mounted in this instrument, and the flashing display, have been concepted in order to

catch user' s attention in case of not proper functioning: defective probe, corrupted memory-data or probe-signal

outside the limits.

The instrument is provided of two pressure alarms, that can be disabled, each of them is configurable in six different

ways of working; the intervention of each alarm activates the acoustic alarm with intermittent beep, at the same time

the display will show "AL 1" (or "AL 2") alternated to the measured pressure value.
