The CAI-201 Thermocouple Interface Card provides
terminal blocks for easy thermocouple connection and
contains the thermocouple cold junction compensation
circuitry. A 50 pin ribbon cable connects the
Thermocouple Interface Card to the CAI-216. In
addition, five analog (-5VDC to +5VDC) inputs are
provides at the 34-pin connector (J2) provides for
additional analog input monitoring.
Thermocouple Upscale Jumpers: The TC Interface Card
has resistors that drive the thermocouple voltage
upscale in the event of an open thermocouple
circuit. This prevents the zone temperature from
“running away” if the thermocouple fails. Jumper
terminals (JP1 to JP16) are provided to enable this
function. |
