Optional high temperature (fluororubber) seal.

The attachments include intermediate pressure regulator, intermediate flow control, blank station board, isolation board, etc.

All ISO valves can be paired with the ROSS Serial Bus system to achieve centralized or distributed I/O control.

Serial Bus Communication System: Integrated Pneumatic and I/O

The ROSS serial bus system is based on Turck's BL67 modular I/O or its own PointBus architecture, supporting DeviceNet ™、 ControlNet ™、 EtherNet/IP ™、 PROFIBUS DP ™  Waiting for mainstream industrial Ethernet and fieldbus protocols.

1. Centralized and remote configuration

Centralized: The valve island is tightly installed with I/O modules, with 8 points per I/O module, connected to sensors and actuators through M12, M8, or M23 connectors.

Remote configuration: Extend valve island and remote I/O through M23 12 pin cable to adapt to distributed layout.

Partition remote: Separate pneumatic valves, I/O modules, and power supplies in enclosures with different levels of protection.

2. Key modules

Communication adapter: RPSSCDM12A（DeviceNet M12）、RPSSCDM18PA（DeviceNet M18）、RPSSCCNA（ControlNet）、RPSSCENA（EtherNet/IP）、RPSSCPBA（Profibus）。

I/O module: 8-point digital input/output (optional PNP/NPN), 2-point analog input/output (0-10 V or 4-20 mA), and 4-point relay output (2 A).

Valve drive module: RPSSV32A, supports 32 point output, drives ISO size 00/0/1/2/3 valves.

Power expansion module: RPSSSE24A, one additional module needs to be added every 12 modules to provide an additional 5V bus current (maximum 1.3 A).

Terminal module: RPSSTERM is used at the end of the bus.

The system supports up to 63 I/O modules, 264 inputs and 264 outputs, with a protection level of IP65/66/67 and a working temperature range of -20 ° C to 60 ° C.
