The S100 air velocity switch is designed to monitor airflow in ducts, air handling units, and hood and laboratory exhausts to warn of airflow degradation. It is also used in industrial processes and electronics systems and enclosures.
Figure 1 5-12VDC and 24VAC/DC Versions of the S100 Switch are Available. Specifications General The S100 Switch monitors airflow. The LED indicator lights green when there is good airflow and lights red for an alarm condition. The relay output signals an alarm condition. Item...
Degree Controls to discuss available customizations for volume orders. Hardware Configuration The S100 Switch is configured to order, with choices for supply voltage and relay output alarm. The part number format is S100 – S - O, where S represents supply voltage and O represents relay output configuration.
The S100 employs push-wire connections for fast, convenient installation. Use 20AWG to 26AWG solid core wire with a maximum insulation diameter of 1.6mm [0.06in]. Note: If you wish to connect to the S100 using wire ferrules, Phoenix Contact 3200645 is suggested. Connector Pinout...
For wire insertion, push the wire with insulation 4mm [0.16in] ± 0.5mm [0.02in] through the hole in the S100 base plate until the stop face is reached. Take care to stop pushing as soon as the stop face is reached as over insertion can buckle small diameter wires.
For a permanent connection, a plastic adhesive may be used. The S100 is a 4-wire device, with 2 wires for power and 2 wires for the alarm output. It employs push-wire connections for fast and easy termination.
