Connecting Low Voltage Switches
Z-MAX relay panels support a variety of low voltage switch types such as:
• Momentary - provides momentary contacts, triggering alternating on/off actions
• Maintained - triggers On action when connection is made, Off action when removed
• Momentary On/Off with On & Off terminals provided - provides momentary
connection to the "On" terminal to trigger an on action, momentary connection to
the "Off". Used with single pole double throw center off (SPDT-CO) switches
• Momentary On/Off with only "IN" or "ON" terminal - used with momentary on,
momentary off, center off switches and must be used in conjunction with either the
part number #rac00-2sc or #rac00-2sb switch input kits to convert from a 1
terminal to a 2 terminal input
• Traditional Sentry Switches and WattStopper AS-100 style switches.
Each Input has a multi-
position screw terminal with
various positions. The
terminal can be pulled off its
base for ease of wiring. Two
possible pinouts are shown.
Please remember to verify the
function of each pin as
labeled on the product with
the device being wired to
ensure that it is wired
correctly.
