Pneumatic Hub Specifications

The following tables provide the operating and mechanical specifications for the Pneumatic Hub.

DO NOT exceed the maximum electrical specifications. Doing so will cause permanent damage to the Pneumatic Hub and will void the warranty.

Main Power Wire Gauge (Stranded, with ferrule) ††, ‡	24	-	18	AWG
CAN Terminal Wire Gauge (Bare Solid/Stranded)	24	-	18	AWG
CAN Terminal Bare Wire Strip Length	0.33	0.35	0.37	in
CAN Terminal Wire Gauge (Stranded, with ferrule) ‡	24	-	18	AWG

†	As of [[[DATE]]], orders made from REV Robotics will ship with the version of the Pneumatic Hub that features Latching WAGO Connectors on the Main power Input and CAN terminal blocks.
††	Due to the input current requirements for the Pneumatic Hub, it is recommended to use the maximum wire gauge possible for the Main Power Input.
‡	If using a ferrule, we recommend using square or hex shaped crimps.

Make sure to consider the current and safety requirements when choosing a wire gauge for any given application.

Compressor Output Specifications

Parameter	Min	Typ	Max	Unit
Continuous Compressor Output Current (See note below)	-	-	15	A
Current Measurement Resolution	-	125	-	mA
Latching WAGO Connectors †
Wire Gauge (Bare Solid/Stranded)	26	-	14	AWG
Bare Wire Strip Length	0.31	0.33	0.35	in
Wire Gauge (Stranded, with ferrule) ††	22	-	18	AWG
Push Button WAGO Connectors †
Wire Gauge (Bare Solid/Stranded)	24	-	16	AWG
Bare Wire Strip Length	0.33	0.35	0.37	in
Wire Gauge (Stranded, with ferrule) ††	24	-	18	AWG

†	As of Summer 2024, orders made from REV Robotics will ship with the version of the Pneumatic Hub that features Latching WAGO Connectors on the Main power Input and CAN terminal blocks.
††	If using a ferrule, we recommend using square or hex shaped crimps.

It is recommended to use a 20A fuse or circuit breaker with the Pneumatic Hub if using a compressor with higher peak current draw, such as the CP26 or the Thomas 405ADC38.

Double-check the specifications of your desired compressor before connecting it to the Pneumatic Hub. Compressors that have an inrush current higher than the compressor switch MOSFET can handle will damage the Pneumatic Hub on start up.

The Pneumatic Hub is not compatible with the 215 series of Thomas compressors.

Solenoid Channel Specifications

Parameter	Min	Typ	Max	Unit
Individual Channel Output Current	-	-	200	mA
Total Continuous Output Current (24V Mode) †	-	-	3.2	A
Total Continuous Output Current (12V Mode) †	-	-	1.5	A
Output Current Measurement Resolution	-	10	-	mA
Wire Gauge (Bare Solid/Stranded)	24	-	20	AWG
Bare Wire Strip Length	0.33	0.35	0.37	in

†	Total combined current for all solenoid channels.

Digital Pressure Switch Port Specifications

Parameter	Min	Typ	Max	Unit
Input Voltage Range †	0	-	5	V
Input High Level Voltage	-	-	2.31	V
Input Low Level Voltage	0.99	-	-	V
Wire Gauge (Bare Solid/Stranded)	24	-	20	AWG
Bare Wire Strip Length	0.33	0.35	0.37	in

†	Internally pulled up to 5V.

Analog Pressure Sensor Port Specifications

Parameter	Min	Typ	Max	Unit
Default Pressure Measurement Range †	0	-	200	psi
Corresponding Voltage Measurement to Pressure Range †	0.5	-	5.0	V
Absolute Voltage Measurement Range ‡	0	-	5.0	V
Supply Voltage	-	5	-	V
Supply Current	-	-	95	mA

†	The Pneumatic Hub assumes a REV Analog Pressure Sensor (REV-11-1107) is connected by default.
‡	The REV Analog Pressure Sensor minimum output voltage is 0.5V. A measurement of 0V triggers a fail safe condition that assumes the sensor has been disconnected.

Mechanical Specifications

Parameter	Min	Typ	Max	Units
Body Length	-	4.375	-	in
Body Width	-	1.875	-	in
Body Height	-	0.750	-	in
Weight	-	0.1625	-	lbs
Mounting Hole Grid Pitch	-	0.5	-	in
Mounting Screw Size (Clearance)	-	#10	-	-
Case Material	-	ABS	-	-

DO NOT use thread-locking fluid on the mounting hardware for the REV Pneumatic Hub. Thread-locking fluid will damage the ABS plastic case.
