Proportional pressure valves type RZMO-AES - 1

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. 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. Valve body MODEL CODE Proportional solenoid The system pressure is controlled by the poppet ብ , directly operated by the proportional solenoid ባ and the spring ቤ. Spring Poppet Integral electronics The integral electronics ቦ ensures factory presetting, fine functionality plus valve-tovalve interchangeability and simplified wiring and installation. 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 Following communication interfaces ቨ, ቩ , ቪ , ቫ are available for the -AES execution: * Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Proportional pressure relief valve size 06 A = without integral transducer AE = as A plus integral electronics AES = as A plus integral digital electronics Series number Communication interfaces (only for AES): PS BC BP EH = 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.

GENERAL NOTES RZMO proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive). Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and in the installation notes supplied with relevant components. The electrical signals of the valve (e.g. monitor signals) must not be directly used to activate safety functions, like to switch-ON/OFF the machine’s safety components, as prescribed by the European standards (Safety requirements of fluid technology...

DIGITAL INTEGRAL DRIVERS -AES - OPTIONS Standard driver execution provides on the 7 pin main connector: Power supply - 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers. Reference input signal - analog differential input with 0÷+10 VDC nominal range (pin D, E), proportional to desired coil current (4÷20 mA with cable break detection, ± 10 mA, ± 20 mA or 0÷20 mA software selectable)...
