Output Drive
There are 3 different output drive options which are designed to fulfill the vast majority
of user requirements and to allow easy integration to PLC equipment.
Option 1 - NPN
Transistor-driven switch which presents a pull-up resistor to 24VDC on the alarm pin.
This configuration is the same for both alarm pins (pin-2 and pin-4).
