Mastermind (S-7/A.0.E.) replacement module.
Sitomatic Process Technology BV
The Mastermind replacement module has been made for the Keystone F784 Mastermind. Thanks to its simple design it allows for fast replacement without the need of changes on either the valve or its mounting slot.
Keystone does no longer produce this component, for this reason the part has been reversed engineered and made compatible with 2.1 and 3.0 AS-interface networks for easy reintegration into the existing network.
