The Signet 8900 Multi-Parameter Controller takes the
concept of modularity to the extreme. Each 8900 is field
commissioned with the users specified combination of inputs,
outputs, and relays using simple-to-install modular boards
into the base unit. To assemble a controller, there is a
choice of two base units offered with a choice of back-lit LCD
or vacuum fluorescent display. Then, continue building with a
selection of plug-in modules for either two, four, or six
input channels which accepts any of the Signet sensors listed
below, and/or other manufacturer's sensors via a 4 to 20mA
signal converter (Signet Model 8058). To complete your unit,
choose a power module with universal AC line voltage or 12 to
24 VDC.
If more features are needed, analog output and
relay modules are available and easily installed. Plus, the
8900 will support up to four additional relays via an external
relay module.
There are other notable features that
the 8900 offers. For instance, digital input to th 8900
enables longer cable runs and simplified wiring with minimal
noise interference. Advanced relays provide "and/or" logic to
produce hi/low alarms. Derived measurements include
difference, sum, ratio, percent recovery, percent rejection,
percent passage, and now with BTU. The menu system can be
programmed to display in multi-languages including English,
German, French, Spanish, Italian, and Portuguese.
Customers with current non-BTU 8900 units can return
their units to the factory for reflashing, free-of-charge. See Pipeline
(dated 5/4/05) for return process procedures, or contact
the factory. |
