Proportional relief valves type RZMO-TERS, AERS
direct operated, with integral or remote pressure transducer, ISO 4401 size 06
RZMO are poppet type proportional
pressure relief valves, direct operated with
integral or remote pressure transducer,
which provide pressure regulation
proportional to electronic reference signals.
They operate in association with electronic
drivers, see section ‫ ,ݘ‬which supply the
proportional valve with proper current to
align valve regulation to the reference signal
supplied to the electronic driver.

They are available in different executions:
• -TERS with integral pressure transducer ‫ܬ‬
plus digital electronics ‫ ܭ‬preset in closed
loop, featuring improved static and
dynamic performances.
• -AERS as -TERS but without integral
pressure transducer (predisposed for
connection of remote pressure
transducer).

Pressure range:

Following communication interfaces ‫ ܮ‬are
available:
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating trough Atos PL software
• -BC, CANopen interface
• -BP, PROFIBUS DP interface
The valves with -BC and -BP interfaces can
be integrated into a fieldbus communication
network and thus digitally operated by the
machine control unit.

Communication interfaces:

Configuration:

The electronic main connector ‫ ܮ‬is fully
interchangeable for -TERS and -AERS
executions. Standard 7 pin connector is
used for power supply, analog input
reference and monitor signals.
12 pin connector is used for option /Z.

The coils are fully plastic encapsulated
(insulation class H), and the valves have
antivibration, antishock and weather-proof
features.
Mounting surface: ISO 4401, size 06
Max flow: 4 l/min
Max pressure: 350 bar.

C = remote pressure transducer with current feedback 4÷20 mA (only for
AERS executions)
