TrustedTM Temperature Input FTA - T8840
GENERAL ASSEMBLY
DESCRIPTION
The Trusted
system and up to eight temperature, voltage or current devices using a
range of available plug in conditioning units. The FTA excludes the
conditioning units to allow maximum configurability. More than one type of
conditioning unit can be used on the same FTA. Compatible conditioning
unit include the 7B series of units from Analog Devices and SCM7B series
from Dataforth.
The Trusted
(CJC) resistor for each of the inputs. This makes the FTA compatible with
Thermocouple conditioning units.
The Trusted
Module using either Companion cables TC-211/212 or Smart Slot cables
TC-511/512. The Output can also be connected to the Analogue Input
module via a VFTA if necessary to be compatible with an existing
installation.
The VFTA is designed to be mounted on either of the TS32 or TS35 DIN
rails in the horizontal or vertical positions as required.
