Exp control unit now standard with alarm contact

Ever more often customers are asking us to equip the Exp control unit with the optional alarm contact.
This contact can be used to generate an alarm when the pressure falls below a certain level, so that one can intervene before the pressure reaches the minimum level and the controller cuts out.
Terminals 21 and 22 are used for this, with the consequence that no second digital valve can be connected to them.

This has no impact on the price, and it can be connected or not as desired.
We have therefore decided that effective immediately we will be offering this as standard.
The existing code is extended with ".1".

Have a look at the datasheet.
