Description

The TSDS Series is designed for more demanding commercial and industrial applications where small size and accurate performance are required. The factory calibration for fixed time delays is within 1% of the target time delay. The repeat accuracy, under stable conditions, is 0.5% of the time delay. The TSDS Series is rated to operate over an extended temperature range. Time delays of 0.1 seconds to 1000 minutes are available. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry. This product is suitable for many applications, including dispensing, welding, and exposure timing. Operation (Single Shot) Input voltage must be applied before and during timing. Upon momentary or maintained closure of the initiate switch, the output energizes for a measured interval of time. At the end of the delay, the output de-energizes. Opening or reclosing the initiate switch during timing has no affect on the time delay. The output will not energize if the initiate switch is closed when input voltage is applied. Reset: Reset occurs when the time delay is complete and the initiate switch is opened. Loss of input voltage resets the time delay and output. Features & Benefits FEATURES BENEFITS Compact, low cost design measuring 2 in.

(6.35 mm) female terminals are constructed with an insulator barrel to provide strain relief. P1015-18 Quick Connect to Screw Adapter Screw adapter terminal designed for use with all modules with 0.25 in. (6.35 mm) male quick connect terminals. C103PM (AL) DIN Rail 35 mm aluminum DIN rail available in a 36 in. (91 .4 cm) length. P1023-20 DIN Rail Adapter Allows module to be mounted on a 35 mm DIN type rail with two #10 screws. External Resistance vs. Time Delay This chart applies to externally adjustable part numbers. The time delay is adjustable over the time delay range selected by varying the resistance across the RT terminals; as the resistance increases the tie delay increases. When selecting an external RT, add the tolerances of the timer and the RT for the full time range adjustment. Examples: 1 to 50 S adjustable time delay, select time delay range 1 and a 50 K ohn RT. For 1 to 100 S use a 100 K ohm RT.
