Catalog 1308242 Issued 3-03 P&B CD series CMOS IC Time Delay Relay 1% Repeatability Operates from -40°C to +55°C Delay on operate or delay on release timing modes Fixed, knob or resistor adjustable types – Calibrated dial on knob adjustable types • 10A output relay with SPDT or 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. Timing Modes Initial Dielectric Strength 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. Between Open Contacts: 500V rms, 60 Hz. Between All Other Conductors: 500V rms, 60 Hz. ON OFF N.O. RELAY CONTACTS ON OFF ➛ INPUT VOLTAGE TIME ➛ Input Data @ 25°C Delay on release – Input voltage must be applied continuously to operate the internal relay. When control Input is applied, the relay energizes. When control input is removed, timing begins. When timing is complete, the relay will de-energize. Time may be reset to zero during timing by reapplying control input. ON OFF N.O. RELAY ON CONTACTS OFF ➛ CONTROL INPUT TIME ➛ Voltage: 24 & 120VAC and 12 through 110VDC.
