NEW 8 Mode version available (see Order Code AS3141-HP-8Mode below): The operation of the extra mode in this version is similar to Mode 3 above but the trigger signal logic is reversed so while trigger signal is present timer is inactive. Loss of the trigger signal starts the countdown delay. Relay turns on at the end of the delay time. Restoration of the trigger signal at any point resets the timer and deactivates relay if active. Useful for a delayed activation output when a control signal drops out e.g. warning buzzer, etc.
