Catalog 1308242 Issued 3-03 P&B CB series CMOS IC Time Delay Relay • Choice of timing modes – Delay on operate – Delay on release – Interval on with or without control switch • Knob adjustable • 10A output relay with SPDT or DPDT contacts • Various models time from 0.1 sec. to 100 min. 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. Timing Modes Contact Data @ 25°C 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. Arrangements: 2 Form C (DPDT), except 8-pin delay on release model has 1 Form C (SPDT). 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 VOLTAGE ON OFF N.O. RELAY ON CONTACTS OFF 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. CONTROL SWITCH Between Open Contacts: 500V rms, 60 Hz. Between All Other Conductors: 500V rms, 60 Hz. ON OFF N.O. RELAY ON CONTACTS OFF TIME Interval on (without control switch) – The relay energizes and timing begins when input voltage is applied. At the end of the time delay period the relay will de-energize. Reset is accomplished by removing, then reapplying, the input voltage. INPUT VOLTAGE Initial Dielectric Strength ON OFF Input Data @ 25°C Voltage: 24 and 120VAC, and 12 and 24VDC. Power Requirement: AC Types: Typically less than 3 VA. DC Types: Typically less than 3 W. Transient Protection: Yes. Reverse Voltage Protection: Yes. Input Voltages & Limits @ 25°C N.O. RELAY ON CONTACTS OFF 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.

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.
