1. Outline

The J-APN 11 Multifunction Rulse-to-Pneumatic Pressure Converter responds to up (upward)and down (downward)pulse signals. It drives pulses and a (four-phase) motor to send out pneumatic pressure signals of 20 to 100[kPa] and current signals of 4 to 20 [mA] DC via a nozzle and a flapper mechanism.
In case of power failure, the converter automatically keeps the pneumatic pressure signal at its pre-failure position (provided that the pneumatic source is in normal operation).

3. Installation and Operation

3-1. Installation

Mount the converter securely on a 2-inch pipe or on a wall. (refer to Specification Sheets :SS2-APN100-0100, the figure for externaldimensions.)

3-2. Operation

Complete wiring and piping according to Figure 3-2-1. Warm up the converter for about 30 minutes before operating.
For air supply, please use the prescribed instrumentation air.

Shield Note 1
Note 1: Ground the cable shield only on the instrument room side (Class 3 or higher).
Note 2: Install the jumpers on the external wiring.
Note 3: Although a large number of additional functions can be selected on the pulse-to-
pneumatic pressure converter, the number of external wires may be limited depending on the conduit dimensions. The cable shapes and the number of wire cores should be your guides when selecting functions.
Note 4: Ground the main unit to Class 3 or higher.
