CRB-48-70030

CR series Recycle Time Delay Relay • Individual ON and OFF time adjustment knobs • 10A output relay with DPDT contacts • Various models time from 0.1 to 180 sec. File E22575 File LR15734 Timing Mode Initial Dielectric Strength Recycle timing – First delay period begins when input voltage is applied. At the end of the first delay, or “off” period, the relay will operate and the second delay, or “on” period, begins. When the second delay period ends, the relay de-energizes. This recycling sequence will continue until input voltage is removed. When input voltage is removed, the relay will deenergize. Between Open Contacts: 500V rms, 60 Hz. Between All Other Conductors: 500V rms, 60 Hz. INPUT VOLTAGE ON OFF N.O. RELAY CONTACTS ON OFF ➛ 1 TIME ➛➛ ➛➛ TIME 2 1 TIME ➛ Input Data @ 25°C Voltage: 120VAC and 24VDC.
