Temperature Controllers
Series HT 52
Self-programmable
microprocessor controller 96 x 96
Maximum protection of high-capacity heaters is achieved through
the start-up circuit and subsequent drying phase. Practical functions
such as self-optimisation, heating circuit control, setting acceptance
where there is a sensor breakage, etc., characterise these control-
lers to give your equipment and machines maximum safety and
reliability as well as helping to lower your production costs or those
of your customers.
The electronic controller HT 52 is also available in the dimensions
96 x 48.

Controller output 1:
6 A / 230 Volt, actuating output: as a two-point
controller relay confi guration (factory setting)
the heating or cooling (cutout) is connected;
as a two-point controller logic confi guration
(selectable), it has an alarm function, with the
setting being input via output 3 (logic)
Controller output 2:
6 A / 230 V, Relay output, in two-point con-
fi guration as an alarm output, in three-point
confi guration as a cooling output
Controller output 3:
Analog signals 0 to 20 mA for actual value,
rated value or setting of the continuous control-
ler; logic level 0 / 6 V (SSR relay) for alarm
functions or the setting of the two/three-point
controller
