Catalog 1308242 Issued 3-03 AGASTAT VTM2 series Off-Delay Timing Module Off-delay timing mode Reliable solid state timing circuitry. 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 25C Voltage:(10%): 12 VAC/VDC, 24VAC/VDC, 120 VAC/VDC. Off-Delay. 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% Overall Accuracy: 2% at R = 1 megohm. Temperature Range: Storage: -40C to +85C.
