Flame retardant, solvent resistant housing. File E60363 File LR33434 Users should thoroughly review the technical data before selecting a product part number. It is recommended that user also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. Timing Mode Input Data 25C Voltage:(10%): 12 VAC/VDC, 24VAC/VDC, 120 VAC/VDC. Interval. Power Requirement: 4W, with rated load. Transient Protection: Non-repetitive transients of the following magni- Timing Specifications tudes will not cause spurious operation of affect function and accuracy. Timing Ranges: 0.5 to 10 / 3 to 60 sec. 3 to 60 min. Operating Voltage <0.1 ms <1 ms Timing Adjustment: External resistor or potentiometer. An external 12, 24 VAC/VDC 860V* 208V* resistance of 1 megohm is required to obtain the maximum time for all ranges. To determine the actual 120 VAC/VDC 2,580V 2,150V* resistance needed to obtain the required time delay, * Min. source impedance of 100 ohms. use the following formula: Current Drain: Less than 5mA. T - T req min R = x 1,000,000 ohms t (T - T ) max min Environmental Data Accuracy: Repeat Accuracy: 1% Temperature Range: Storage: -40C to +85C. Overall Accuracy: 2% at R = 1 megohm.
