Manufactured by Hurtwood.
Using Modbus it is possible to connect to most building management systems.
Satrofit I/O Cards
Satrofit SRC-UNC-16 BMS input and output cards plug directly into UNC 696 or 796
racks and read all the pre-existing Satchwell sensors. The output cards can drive
the Satchwell 8 way latching relay cards.
Satrofit cards are a powerful and cost effective input & output system and because they use Modbus, they can be utilised with a wide variety of BMS master controllers.
Satrofit Terminal Controller
The Satrofit SRC-AUNC-6-6-3 controller is a direct physical replacement for the popular Satchwell IAC 420 controller. The controller has a number of pre-set control strategies for building services such as small boiler houses and fan-coil units. The selection of and set-up of these programs can be carried out through the Satrofit tool. Additional control programs for bespoke applications can be provided on request by Hurtwood.
The Staefa Retrofit 48IO cards plug directly into the housing for the original NRUA/A to NRUD/A Integral RSM series of controllers and have connectors for the ribbon cables of the original NTIM and NTOM modules. They can read all the pre-existing Staefa sensors.
Like the Satrofit cards, Staefa Retrofit cards are a powerful and cost effective input/output card and a wide variety of ribbon cable connected input and output modules are available. Variations to suit particular customers’ requirements and to meet any retrofit application can be built on demand. Just get in touch.
Hurtwood also manufacture replacement modules for the NTIM and NTOM racks allowing the Staefa system to be maintained and added to for many decades to come.
