Analog Retransmit Outputs
Each sensor input signal level is made available at an “Analog Retransmit” output for
chart recording or other uses. See Terminals 1,2,3,4 and 11, page 35. The scaling
of these outputs varies with sensor type and function. The following is a summary of.
the
scaling:
RTD Units
-0500VDC = -1 00.0°F
0.000VDC = 0.0°F
+5.000VDC = 1 000.0°F
O.OOOVDC = 0°C
1.250VDC = 250°C
2.500VDC = 500°C
If using %RH
0.000VDC = 0.0%RH
0.500VDC = l00.0%RH (If using 0 - 0.500V option)
5.000VDC = 1 00.0%RH (If using 0 - 5.000V option)
T T/C Units
-0.500VDC = -1 00°F
0.000VDC = 0°F
5.000VDC = 3200°F
0.l00VDC = -64°C
0.000VDC = 0°C
2.750VDC = 1 760°C
Thermocouple types which use only parts of the -100 to +3200 degree range will
have a corresponding part of the retransmit voltage range.
