Proportional relief valves type RZMO-AES
direct operated, without integral pressure transducer, ISO 4401 size 06
RZMO are poppet type proportional
pressure relief valves, direct operated
without integral pressure transducer, which
provide pressure regulation proportional to
electronic reference signals.

9

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:
• -A, without integral pressure transducer.
• -AE, -AES, as -A plus analogue (AE) or
digital (AES) integral electronics ቦ.

Proportional solenoid

The system pressure is controlled by the
poppet ብ , directly operated by the
proportional solenoid ባ and the spring ቤ.

Poppet
Integral electronics

The integral electronics ቦ ensures factory
presetting, fine functionality plus valve-tovalve interchangeability and simplified
wiring and installation.

RZMO-AES-BC-010/*

Main connector
-BC / -BP Communication connector
-PS Communication connector (1)

The electronic main connector ቧ is fully
interchangeable for -AE and -AES
executions. Standard 7 pin connector is
used for power supply, analog input
reference and monitor signals.
12 pin connector is used for option /Z (AES).

-EH Communication connector (input)
-EH Communication connector (output)
Screw for air bleeding

= Serial (1)
= CANopen
= PROFIBUS DP
= EtherCAT

Coil voltage (only for -A execution)
see section ‫:ݛ‬
- = standard coil for 24VDC Atos drivers
6 = optional coil for 12VDC Atos drivers
18 = optional coil for low current drivers
Electronics options
for -AE execution, see section ‫:ݝ‬
I = current reference input (4÷20 mA)
Q = enable signal

Configuration:
010 = regulation on port P, discharge in T
Pressure range:

• -PS, Serial communication interface for
configuration, monitoring and firmware
updating through Atos PC software always present also for -BC,
-BP and -EH options
• -BC, CANopen interface
• -BP, PROFIBUS-DP interface
• -EH, EtherCAT 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.
The coils are fully plastic encapsulated with
insulation class H.
Mounting surface: ISO 4401, size 06
Max flow: 4 l/min
Max pressure: 350 bar.

Electronics options
for -AES execution, see section ‫:ݟ‬
Q = enable signal
Z = adds double power supply,
enable and fault signals

50 = 50 bar
100= 100 bar
210 = 210 bar
315 = 315 bar
350 = 350 bar
