TDMS
The TDMS has universal contact/solid-state inputs:
Note: 1kΩmax. for contact closed
Note: 100kΩmin. for contact open Note: Signal inputs approx. 6VDC open circuit and approx. 2mA when short-circuited
When powering the 24VAC/DC mode using DC, the supply positive lead should be connected to ter minal 7.
