Catalog 1308242 Issued 3-03 Specifications and availability subject to change. www.tycoelectronics.com Technical support: Refer to inside back cover. 2100 series Miniature Electropneumatic Timing Relay Users should thoroughly review the technical data before selecting a product part number. It is recommended that users 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. Design Features • High Repeat Accuracy over voltage and temperature extremes • Hermetically sealed units are designed for high shock and vibration applications • Instant recycling – easy linear adjustment • Exclusive Dial Head adjustment – no needle valves • Delay ranges from milliseconds to 3 minutes • DPDT contacts Design & Construction Sealed patented timing head circulates air under controlled pressure through a variable orifice to provide adjustable timing. Circular-path Dial Head principle replaces traditional needle valve. Snap-action switch assembly provides sustained contact pressure during timing cycles. Specially designed over center mechanism assures flutter- free load transfer after extended delay periods. Precision-wound solenoid assembly supplies the basic motive force when the control circuit is closed. These assemblies are mounted in a rigid self-supporting framework within a steel enclosure. This rugged construction assures permanent alignment of all operating members, the key to this unit's long trouble-free operation. Operation Series 2112 (On-Delay) - Applying rated voltage to the solenoid coil starts the preset time delay. At the end of the delay period the NC contacts break and the NO contacts make. Contacts remain in this position until the coil is de- energized, when the switch instantaneously returns to its original position. De-energizing the coil, either during or after the delay period, will immediately (within 25 msec.) re- cycle the unit. It will then provide another full delay period on re-energization. Series 2122 (Off-Delay) - Applying rated voltage to the coil for at least 75 msec. (for accurate timing) will instanta- neously transfer the switch, breaking the NC contacts and making the NO contacts. Contacts remain in this position as long as the coil is energized. The preset time delay period begins as soon as the coil is de-energized, at the end of which the switch returns to its original position. No power is required during the timing period. Re- energizing the coil, either during or after the delay period, will immediately start a new cycle with full delay period. Repeat Accuracy: NORMAL VERTICAL POSITION +5% at 25°C; +7% at 85°C; +8% at -55°C. The average time between -55°C and 85°C will be within +20% of the average @ 25°C with a proportionally reduced effect at lesser extremes. In extremely short delay settings an additional 8 msec. variation may result on AC models due to "half cycle" alternating current effect. Setting Tolerance: Factory time setting, when specified, subject to addition- al +5% tolerance. Position Sensitivity: HORIZONTAL POSITION: Approximately 5% increase from the initial time in the vertical position. INVERTED POSITION: Approximately 10% increase from the initial time in the vertical position. Reset Time: 2112 Series: 25 msec.; 2122 Series: 75 msec. Relay Release Time: 25 msec.

Mounting/Terminals: Chassis mounting tabs, octal plugs and external (-4) or internal (-5) adjustment. Panel mounting back plate, internal adjustment, and solder hook terminals (-9). Operation (Listed values at nom. voltage, 25°C unless noted). Operating Mode: 2112: On-delay (delay on pull-in); 2122: Off-delay (delay on drop-out) Timing Adjustment: All standard models offer easy linear adjustment over one of nine timing ranges listed below. For applications requiring frequent readjustment, the external knob model with calibrated dial is recommended. For tamper-proof installation or where readjustment is infrequent, the internal key model may be preferred. This model requires removal of the cover plate for timing adjustment. Hermetically sealed models provide a slotted adjusting screw under the cap nut on the top cover. Timing Ranges: Code Range Code Range A .03 to .1 sec. G 2.0 to 60.0 sec. B .1 to .3 sec. H 5.0 to 120.0 sec. C .15 to 1.0 sec. J 5.0 to 180.0 sec. D .375 to 3.0 sec. K 1.5 to 30.0 cycles E .75 to 10.0 sec. L 3.0 to 120.0 cycles F 1.0 to 30.0 sec. --4 --5 --9 These are minimum standards; where more severe environmental conditions must be met, please consult the factory. |
