These relay contacts may be used to control any equipment as long as the contact
specifications of a total of 24 V at 1 A are not exceeded for each port. These relays are
normally open by default.
When activated, the open contacts close. They can be set up to operate in one of two
ways:
•
Latching (brief or indefinite period contact) (press to close, press to open), or
•
Pulsed (timed cycle) (press to close, timeout to open, with automatic repeat).
In pulse mode the default timeout period (hold time) is ½ second (500 ms). Use Global
Configurator to change the length of the timeout period.
NOTE: The pulse function is absolute: it always sets the relay state to closed, times
out (briefly), then opens the contact. It overrides the previously selected setting (on
state, off state, or toggle).
• Connect devices for contact control.
• Do not exceed a total of 24 V at 1 A for each port.
