1. DESCRIPTION
The
PCT-120e
plus
is an easy to install and operate two-stage pressure controller designed for
systems that require effective pressure control. Operating in pressurization, despressurization,
refrigeration, heating or alarm mode, it directly controls loads of up to 1HP. It also has digital inputs that
allow external devices to be used for protecting the controller system, hourmeters that store the number
of hours compressors/pumps are operating and indicate when maintanance should be performed on
them. Operating in combination with temperature sensors, it also performs dynamic and adiabatic
condensation control, dynamic evaporation, superheating and subcooling monitoring, promoting
greater energy efficiency in the system. It also has serial output for communication with Sitrad and an
intelligent locking function, preventing unauthorized persons from changing the control parameters.
2. APPLICATIONS
•
Control over suction or discharge in refrigeration systems, air compressors, semi-artesian pumps,
water tanks and filters, superheating and subcooling monitoring.

WARNING
FOR INSTALLATIONS THAT REQUIRE WATER TIGHTNESS, THE OPENING TO INSTALL THE CONTROLLER MUST BE 71,5 x 29,5 mm
(28,15 x 11,6 in) MAXIMUM. THE SIDE LATCHES MUST BE FIXED SO THAT THEY PRESS THE SEALING GASKET TO PREVENT
INFILTRATION BETWEEN THE OPENING AND THE CONTROLLER.
