CK series Mid-Priced CMOS IC Time Delay Relay • Choice of timing modes – Delay on operate – Delay on release – Delay on dropout (no input required during timing) – Interval on • Knob or resistor adjustable types • 10A output relay with DPDT contacts • Various models time from 0.1 to 180 sec. File E22575 File LR15734 Contact Data @ 25 °C Arrangements: 2 Form C (DPDT). Material: Silver-cadmium oxide alloy. Rating: 10A @ 30VDC or 277VAC, resistive; 1/2 HP @ 250VAC; 1/3 HP @ 120VAC. Expected Mechanical Life: 10 million operations. Expected Electrical Life: 100,000 operations, min., at rated load. Input Data @ 25 °C Voltage: 24 & 120VAC and 12 & 24VDC. Power Requirement: AC Types: Typically less than 3 VA. DC Types: Typically less than 3 W. Initiate Time: Delay on dropout timers must have input voltage applied for a minimum of three seconds for dropout function to be guaranteed. Transient Protection: Yes. Reverse Voltage Protection: Yes. Environmental Data Temperature Range: Storage: -55 °C to +85°C. Operating: -10 °C to +55°C. Mechanical Data Termination: 8- or 11-pin octal style plug. Enclosure: White plastic case. Knob adjustable types have dial scale for reference only. Sockets: Models with 8-pin base fit either 27E122 or 27E891 (snap-on) screw terminal sockets. 11-pin types fit either 27E123 or 27E892 (snap-on) screw terminal sockets. Weight: 6 oz. (170g) approximately. Timing Modes Delay on operate – Delay period begins when input voltage is applied. At the end of the delay period, the relay will operate and will not release until input voltage is removed. Reset occurs when input voltage is reapplied. Delay on release – Input voltage must be applied continuously to operate the internal relay. When the control switch is closed, the relay energizes. When the control switch is opened, timing begins. When timing is complete, the relay will de-energize. Time may be reset to zero during timing by closing the control switch. Delay on dropout – The relay operates immediately upon application of input voltage. Timing begins when input voltage is removed. When timing is complete, the relay will de-energize. Reset occurs when input voltage is reapplied. Interval on (with control switch) – Input voltage must be applied continuously to operate the internal relay. The relay energizes and timing begins when the external switch is closed. At the end of the time delay period the relay will de-energize. Reset is accomplished by opening and reclosing the control switch. Timing Specifications Timing Ranges: From 0.1 to 180 sec. Timing Adjustment: External resistor and knob adjustable.
