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 which is started by applying input voltage. LED flashes when output relay 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. Between Output Poles: 1,500V rms, 60 Hz. Between Input and Output: 1,500V rms, 60Hz. INPUT VOLTAGE N.O. RELAY CONTACTS Input Data @ 25°C ➛ ON OFF ON OFF TIME Voltage: 120VAC ± 15%, 60 Hz. Power Requirement: 3VA @ 120VAC. Transient Protection: 13 Joule MOV. ➛ Timing Specifications Input Voltage & Limits Timing Ranges: 0.1 to 99.9 / 1 to 999 sec.; 0.1 to 99.9 / 1 to 999 min.; 0.1 to 99.9 / 1 to 999 / 10 to 9,990 hr. Timing Adjustment: Digital adjustment via thumbwheel switches. Tolerance: ± 0.05% ± 0.04 sec.* Repeatability (Including first cycle of operation.): < ± .05% ± 0.04 sec.* Reset Time (power interruption): 45 ms, typ.; 60 ms, max. * Timing is synchronized with input voltage frequency. Accuracy is dependent on input voltage frequency. Tolerance shows maximum variation from utility companies.
