1.2.11 BMS Module Valve
The BMS Module valve output is
intended to drive the ESD valve. It
has user-adjustable peak-and-hold
capability. The output voltage is the
same as POWER IN+. The maximum
current output is 2 amps (Image
1.2.11).
1.2.12 BMS Module
Thermocouple Inputs
TC1 & TC2
Thermocouple inputs TC1 &
TC2 accept a dual-probe k-type
thermocouple. They are not to be
used for separate thermocouples.
It can be used as a source for the
Processes and Shutdowns. It is
always used for the high-temperature
shutdown, TEMP LIMIT. If a dual-
probe thermocouple is not being
used, TC1 & TC2, individually, need to
be jumpered. (Image 1.2.12).
