Signal Isolations
•
PV input terminals: Isolated from other input/output terminals. Not isolated from the
internal circuit.
•
15 V DC loop power supply terminals: Not isolated from 4-20 mA analog output and
voltage pulse control output. Isolated from other input/output terminals and internal
circuit.
•
4-20 mA analog output terminals (for control output and retransmission): Not isolated
between 4-20 mA outputs and from 15 V DC loop power supply and voltage pulse
control output. Isolated from other input/output terminals and internal circuit.
•
Voltage pulse control output terminals: Not isolated from 4-20 mA outputs and 15 V
DC loop power supply. Isolated from other input/output terminals and internal circuit.
•
Relay contact control output terminals: Isolated between contact output terminals and
from other input/output terminals and internal circuit.
•
Contact input terminals: Not isolated between contact input terminals and from com-
munication terminals. Isolated from other input/output terminals and internal circuit.
•
Relay contact event output terminal: Not isolated from each other; isolated from other
input/output terminals and the internal circuit.
•
RS-485 communication terminals: Not isolated from contact input terminals. Isolated
from other input/output terminals and internal circuit.
•
Power terminals: Isolated from other input/output terminals and internal circuit.
•
Grounding terminals: Isolated from other input/output terminals and internal circuit.

Effects of changes in operating conditions
-
Effects from changes in ambient temperature:
-
On voltage or thermocouple input,
1
V/
C or

C,
whichever is larger
-
On RTD input,
0.05
C/
