The H Series ISO series valve (size 1, 2, and 3) is an internal/external air piloted subbase style valve.  Available valve functions are 5/2, single and double solenoid - 5/3, all ports blocked in the center position, double solenoid.  The H Series ISO size 1, 2, and 3 valves can be configured as plugin or non-plugin, and can be mounted on a stand alone subbase or on a multiple valve manifold. The size 1 has a subbase with 3/8 NPT/BSPP side ports or a manifold with 3/8 NPT/BSPP side and bottom ports. The size 2 has a subbase with 1/2 NPT/BSPP side ports and manifold options with 1/2 NPT/BSPP bottom and side ports. The size 3 has a subbase with 3/4 NPT/BSPP side ports and a manifold with 3/4 NPT/BSPP bottom and side ports.
In the case of the plugin style valve on a subbase, the wiring options are a terminal block, 6" lead wires, 4 pin M12, or 3 pin or 5 pin mini. On a manifold, the wiring options are a terminal block or 6" lead wires, or circuit boards in the base for collective wiring. The collective wiring options are:
   1• 25 pin Dsub
   2• M23 12 pin or 19 pin
   3• 19 pin Brad Harrison
   4• Valve driver module that connects the valve bank to an industrial network such as Ethernet I/P, Devicenet, Controlnet, Profibus, Canopen, ASi, Interbus-Modbus/TCP,  or Profinet
In the case of the non-plugin style valve, it can be mounted on a subbase or manifold, but the coils are wired directly with cables. In the case of non-plugin, cables are wired directly to the coils with a 30mm 3 pin DIN connector (ISO 4400 DIN 43650A). The ISO size 1, 2, and 3 valves can be field converted easily from internal to external pilot supply by flipping the gasket under each coil operator. Internal pilot operation means the supply pressure on the #1 port is directed to the end of the valve where the solenoid operator, when actuated, allows the supply pressure to pass, which is then applied to the piston to shift the spool. External pilot is when the valve gets its "internal" pressure from an "external pilot port" instead of the #1 port. These valves can be used with Isysnet, Turcknet, or Moduflex fieldbus.
