OVERVIEW
The NTTA01 Translator Termination Unit interfaces high level
signals (four to 20 milliamps and one to five VDC) to a low level
signal (15 to 73 millivolts) IMASM02 Analog Slave Module for
up to 250 VDC common mode rejection. The IMASM02 Analog
Slave Module is a slave to the IMAMM03 Analog Master
Module.
The translator termination unit (TTA) has eight analog inputs.
Translator termination units can be interconnected for config-
urations requiring more than eight inputs. Each termination
unit requires an IMASM02 module. Figure
shows an exam-
ple TTA application.
