Note
TB2
-9 and TB2-11 are Open Collector Outputs that require external pull-up resistors for
operation. See table for External Supply Voltage and suggested resistor value and ratings.
Maximum current into the transistor is 100mA. Maximum Voltage is +36 VDC.
NOTICE
Transistor Damage
Negative voltages with respect to ground will permanently damage transistors.
Use caution when applying power to circuit boards.
