SIGNAL WIRING
Meter signal input common is not isolated from PGM.DIS,
E1-CON, E2-CON, and +EXC. Maximum allowable 50 V can be
present in the circuit that is being measured.
Two Wire Transducers Requiring Excitation:
Connect the “+” lead of the transducer to TBA #7, “+EXCITATION”, and the
“-” lead to TBA #6, “+SIGNAL”. Refer to the transducer manufacturer’s data
sheet supplied with the transducer for proper connections.
Note: The common of the excitation voltage is connected internally to “COMM”
(TBA #5).

A.C. Power Basic Connection w/Internal 18V Excitation
For Signal Sources Not Requiring Excitation:
Connect the “+” lead of the process signal to TBA #6, “+SIGNAL”, and the
“-” lead of the signal to TBA #5, “COMM”. Regardless of the signal level of the
process (4 to 20 mA or 10 to 50 mA, etc.), the indicator automatically adapts to
the proper range. Refer to the transducer manufacturer’s data sheet supplied
with the transducer for proper connections.
