These 2-wire (loop-powered) I/P transmitters accept a current signal (such as 4-20mA) from a DCS, PLC or PC-based control system. They convert the current signal to a pneumatic signal (3-15psig, 0.2-1bar, 20-100kPa, etc.) to provide precise, proportional control of valves, actuators and other pneumaticallycontrolled devices. The economical IPH2 (Type 4X) is watertight, dust-protected, and resistant to corrosion and chemicals. In addition to meeting Type 3X/4X requirements, the IPX2 can be installed in explosionproof environments. Both units are available with an optional coalescing ﬁ lter/regulator that combines an air ﬁ lter and miniature supply line regulator with a pressure gauge that reads in both psig and bars.
