PTE3000 Pressure Tolerant Ethernet I/O Board
The PTE3000 is a Pressure Tolerant Ethernet I/O Board with a 32 integrated PWM valve drive driver. 16 valves can be activated simultaneously. The PTE3000 is designed using components proven to withstand the extreme pressure of an underwater environment, without the need for a pressure vessel. To operate underwater, the PTE3000 is installed in a non-conductive, oil compensated environment.
A valve pack, the EVP3000, that incorporates the PTE3000 is also available for purchase.
The following Cellula products use the PTE3000:
A Closer Look at the PTE3000 Board Components
The PTE3000 board has an Ethernet interface processor that controls two parallel IO processors. 16 PWM channels include valve driver electronics with dither. The PTE3000 can also be used as a data multiplexer, with analog, digital and serial interfaces.
The PTE3000 includes software to control each PWM output and monitor all digital and analog inputs. The test software can control two different PTE Boards at the same time. A comprehensive API is available for integration into a client's system.
Test software provides quick setup and testing. A comprehensive API supports system integration.
Distributed control and 50 Hz sampling ensures high performance standards.
Eliminates pressure vessels and reduces the number of connectors needed in your projects.
The PTE3000 is efficiently packaged in oil compensated assemblies.
