Variable AssignmentChannel 2500 2700 Configuration Option Power
A 21 & 22 1 & 2 mA output 1
(with Bell 202 HART)
Mass flow Internal
B 23 & 24 3 & 4 mA output 2 (default)
(1)
(1) If set to MAO2, internal power is required.
Density Internal or external
(2)
(2) If set to external power, you must provide power to the outputs.
Frequency output (FO) Mass flow
Discrete output 1 (DO1)
(3)
(3) Because DO1 uses the same circuitry as the frequency output, it is not possible to configure both FO and DO1. If both a frequency
output and a discrete output are required, configure Channel B as the FO and Channel C as DO2.
Fwd/Rev
C 31 & 32 5 & 6 FO (default)

(4) When configured for two FOs (dual pulse), FO2 is generated from the same FO signal sent to the first FO. FO2 is electrically isolated
but not independent.
