Description
The TS441165 is an analog delay-on-make timer with a normally closed solid-state output. Unlike an interval timer, the load is energized prior to and during the time delay period. It can be used as a faster starting interval time delay when S1 is closed upon application of input voltage. Operation (Delay-on-Make NC) Upon application of input voltage, the load is energized immediately. When the initiate switch is closed, the time delay begins. At the end of the time delay, the load de-energizes. Reset: When the initiate switch is reopened, the load again energizes and the time delay is reset. Removing input voltage resets the time delay and output. Features & Benefits FEATURES BENEFITS Analog circuitry Repeat Accuracy + / - 2% Compact, low cost design Allows flexiblility for OEM applications 1A steady, 10A inrush solid-state output Provides 100 million operations in typical conditions. Load energized prior to and during time delay Faster operation T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity Normally closed output Can be used as a faster starting interval time delay Accessories P1004-XX, P1004-XX-X Versa-Pot Panel mountable, industrial potentiometer recommended for remote time delay adjustment.
