Catalog 1308242 Issued 3-03 P&B CN1 series On Delay, Time Delay Relay For Plug-In or Panel Mounting • 0.1 sec. to 9,990 hr. timing range • Fixed input type (120VAC ± 15%) • 10A output relay with DPDT contacts • 1/16 DIN style enclosure with 8-pin plug-in base • Thumbwheel switches for programming delay time 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 Function Initial Dielectric Strength On Delay – Output relay turns on at the end of a programmed time interval Between Output Poles: 1,500V rms, 60 Hz. which is started by applying input voltage. LED flashes when output relay Between Input and Output: 1,500V rms, 60Hz. is off and is on continuously when the output relay is on. Removal of input voltage turns off output relay. Reapplying input voltage resets the unit. INPUT ON Input Data @ 25°C VOLTAGE OFF ➛Voltage: 120VAC ±15%, 60 Hz. N.O. RELAY ON TIME➛ CONTACTS OFF Power Requirement: 3VA @ 120VAC. Transient Protection: 13 Joule MOV.
