Viking Versatile Time Delay Relay Vikings model TDR-1 is a time delay relay device designed to be easily configured to fit a wide variety of applications. The TDR-1 has two different modes of operation: 1) In the Time Delay Mode, the TDR-1 can be programmed to produce one of 8 closure times. The Trigger 1 input can be programmed to accept either a dry contact closure or positive/negative going logic level voltage. 2) The Delay on Operate mode delays an input trigger by a programmed interval. Eight delay times are available, from 1 to 30 seconds. Applications Controlled closure times Delayed closures Convert closures between N/O and N/C Features 1 Double Pole, Double Throw relay output 8 selectable closure times DIP switch programming Accepts positive or negative going logic level voltage or contact closure Selectable time delay Screw terminal connections LED relay status indicator Specifications Power: 120V AC to 12V DC adapter provided Dimensions: 74mm x 53mm x 25mm (2.9in x 2.1in x 1.0in) Shipping Weight: 0.4 kg (0.86 lbs) Environmental: 0deg C to 32deg C (32deg F to 90deg F) with 5% to 95% non-condensing humidity Relay: 1A 30VDC 110 VDC, 0.5A 125VAC Connections: 10 position cage clamp terminal strip
