Emerson AMS 6500 - Sysfail Relay Termination; Loop Interconnection for 4-20 Ma Current

CAUTION!
The -24 V Eddy Current sensor power input requires a -24 V power supply. Do not connect the
+24 V power supply intended for powering the A6560, A6560R, or A6510 to this input. Verify
all power supply connections are wired and connected properly before powering the unit.
6.9 SysFail relay termination
The SysFail relay output connector is labeled SYSFAIL RELAY, and located on the
bottom left corner of the A6500-M-BP backplane.
The SysFail relay output can be terminated as either normally-open (terminate to C and
NO) or normally-closed (terminate to C and NC).
CAUTION!
The SysFail relay connection is an output for relays only. Do not connect the +24 V power
supply intended for powering the A6560, A6560R or A6510, or the -24 V power supply
intended for Eddy Current Probe power to this output. Verify all power supply connections are
wired and connected properly before powering the unit.
6.10 Loop interconnection for 4-20 mA current
To convert the milliamp signal to a voltage signal, install a 250 ohm resistor between the +
and - signal inputs when connecting 4-20 mA signal inputs.
