Circuit board options with following assemblies:

1. Two microswitches (open/closed), a double terminal block (4-poles) and a
3-pole terminal block for a solenoid valve.

2. Three microswitches (open/closed and a mid position) with one double
terminal block (3- and 4-poles) and a terminal block to connect a solenoid
valve.

3. Two V3-proximity switches (open/closed) , 4-pole double terminal block and
a 3-pole double terminal block for a solenoid valve.

4. Three V3-proximity switches (open/closed/mid position), a 3- or 4-pole
double terminal block a, a 5-pole double terminal block for a double inductor
solenoid valve.

1 1 1 5. Two slot indicators (open/closed, end position alive or dead), a 4-pole
double terminal block and a 3-pole double terminal block for a solenoid
valve.
6. Two M8 round proximity switches (open/closed) , a 4-pole double terminal
block and a 3-pole double terminal block for a solenoid valve.

block and a 3-pole double terminal block for a solenoid valve.

The basic circuit board can be assembled with microswitches or proximity switches
in different forms: V3, cylindric or slotted. Colour coded spring terminals (separated
for sensors and solenoid valves) ensure a safe and correct wiring. Bridging of
supply voltage for sensors and solenoid valves on request.

The bottom section of the switch box is directly mounted on the actuator. Three
gland openings allow a large variety of connection.
