Bank 2

For orientation, the D-sub connector end of the module is facing you.

*TSIL represents Temperature Sensor Interface Line. This line is used for temperature interface only.

WARNING As a safety feature, interlock 1 pins (17 and 33) on Bank 1 must be shorted to enable the Bank 1 Analog Bus relays to close. The optional 34921T terminal block shorts these pins for you. This feature protects inadvertent routing of high voltages from the Analog Bus to the D-sub connector of the module.

*TSIL represents Temperature Sensor Interface Line. This line is used for temperature interface only.

WARNING As a safety feature, interlock 2 pins (17 and 33) on Bank 2 must be shorted to enable the Bank 2 Analog Bus relays to close. The optional 34921T terminal block shorts these pins for you. This feature protects inadvertent routing of high voltages from the Analog Bus to the D-sub connector of the module.
