Excellent transient protection. Compact design. 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 @ 25°C One Shot (Latching Interval). Voltage:(±10%): 12 VAC/VDC, 24VAC/VDC, 120 VAC/VDC. Power Requirement: 4W, with rated load. Transient Protection: Non-repetitive transients of the following magnitudes will not cause spurious operation of affect function and accuracy. Operating Voltage <0.1 ms <1 ms 12, 24 VAC/VDC 860V* 208V* 120 VAC/VDC 2,580V 2,150V* Timing Specifications Timing Ranges: 0.5 to 10 / 3 to 60 sec.; 0.5 to 10 / 3 to 60 min. Timing Adjustment: External resistor or potentiometer. An external resistance of 1 megohm is required to obtain the maximum time for all ranges. To determine the actual resistance needed to obtain the required time delay, use the following formula: Treq - Tmin x 1,000,000 ohms max - Tmin Accuracy: Repeat Accuracy: ± 1% Overall Accuracy: ± 2% at R = 1 megohm. Reset Time: 50 ms, max. (T Rt = ) * Min. source impedance of 100 ohms. Current Drain: Less than 5mA. Environmental Data Temperature Range: Storage: -40°C to +85°C. Operating: -40°C to +65°C. Output Switch Data Arrangement: Solid state 1 Form A (SPST-NO). Rating: 1A, inductive, at nominal operating voltage. Expected Electrical Life: 100,000,000 operations at rated load. Mechanical Data Mounting: Panel mount with one #8 screw. Termination: 0.250 in (6.35) quick connect terminals. Weight: 4 oz. (112g) approximately. Initial Dielectric Strength Between Terminals and Mounting: 3,000VAC rms. Between Input and Output: 1,500VAC rms.
