Catalog 1308242 Issued 3-03 P&B 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 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. Contact Data @ 25°C 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. ON OFF ON OFF ➛ INPUT VOLTAGE N.O. RELAY CONTACTS ➛ TIME 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. ON OFF N.O. RELAY CONTACTS ON OFF ➛ CONTROL SWITCH TIME ➛ 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. ON OFF ON OFF ➛ INPUT VOLTAGE N.O. RELAY CONTACTS TIME ➛ 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. ON OFF N.O. RELAY CONTACTS ON OFF TIME Input Data @ 25°C Voltage: 24 & 120VAC and 12 & 24VDC.

A 50 millisecond minimum switch closure is required. IMPORTANT: A dry circuit switch is recommended. A “dry circuit” switch is one rated to reliably switch currents of less than 50mA. Use of a switch rated for other than dry circuit may result in failure of the time delay relay to function properly. ** Note: Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”.
