The controller enclosure is constructed of a plastic base plate 

and a plastic factory-snap-on cover.

The controller mounts using four screws inserted through the 

corners of the base plate. Fasten securely with four No. 6 or 

No. 8 machine or sheet metal screws.

The controller can be mounted in any orientation. Ventilation 

openings are designed into the cover to allow proper heat 

dissipation, regardless of the mounting orientation.

To mount the PUB1012S, PUB4024S, PUB6438S, 

PVB4024NS and PVB6438NS controllers on a DIN rail 

[standard EN50022; 1-3/8 in. x 9/32 in. (7.5 mm x 35 mm)], 

refer to Fig. 8 and perform the following steps:

1. Holding the controller with its top tilted in towards the DIN 

rail, hook the two top tabs on the back of the controller 

onto the top of the DIN rail.

2. Push down and in to snap the two bottom flex connectors 

of the controller onto the DIN rail.

For PVB0000AS, PVB4022AS, PVB4024NS, PVB6436AS and 

PVB6438NS, connect the air flow pickup to the two restrictor 

ports on the controller (see Fig. 9).

NOTES:

—

Use 1/4 inch (6 mm) outside diameter, with a 0.040 

in. (1 mm) wall thickness, plenum-rated 1219 FR 

(94V-2) tubing.

—

Always use a fresh cut on the end of the tubing 

that connects to the air flow pickups and the 

restrictor ports on the controller.

Connect the high pressure or upstream tube to the plastic 

restrictor port labeled (

+

), and the low pressure or downstream 

tube to the restrictor port labeled (

-

). See labeling in Fig. 9. 

When twin tubing is used from the pickup, split the pickup 

tubing a short length to accommodate the connections.

NOTES:

—

If controllers are mounted in unusually dusty or dirty 

environments, an inline, 5-micron disposable air 

filter (use 5-micron filters compatible with 

pneumatic controls) is recommended for the high 

pressure line (marked as 

+

) connected to the air 

flow pickup.

—

The tubing from the air flow pickup to the controller 

should not exceed three feet (0.914 m). Any length 

greater than this will degrade the flow sensing 

accuracy.

—

Use caution when removing tubing from a connec-

tor. Always pull straight away from the connector or 

use diagonal cutters to cut the edge of the tubing 

attached to the connector. Never remove by pulling 

at an angle.

Before wiring the controller, determine the input and output 

device requirements for each controller used in the system. 

Select input and output devices compatible with the controller 

and the application. Consider the operating range, wiring 

requirements, and the environment conditions when selecting 

input/output devices. When selecting actuators for modulating 

applications consider using floating control. In direct digital 

control applications, floating actuators will generally provide 

control action equal to or better than an analog input actuator 

for lower cost. 

Determine the location of controllers, sensors, actuators and 

other input/output devices and create wiring diagrams. Refer to 

Fig. 17–Fig. 23 beginning on page 14 for illustrations of typical 

controller wiring for various configurations.
