* Type R power supply may require 14 Vdc to begin operation. Once operating, the voltage may be
reduced to 12 Vdc.
Radio Frequency Interference (RFI)
Field-tested using a five-watt, hand-held transceiver operating at random frequencies centered around
144 MHz and 440 MHz, with the antenna located six inches from the relay in both horizontal and vertical
planes.
Isolation
In accordance with IEC 255-5 and ANSI/IEEE C37.90, one-minute dielectric (high potential) tests as
follows:
All circuits to ground ........................ 2,121 Vdc
Input to output circuits ..................... 1,500 Vac or 2,121 Vdc
Surge Withstand Capability
Qualified to ANSI/IEEE C37.90.1-1989, Standard Surge Withstand Capability (SWC) Tests for Protective
Relays and Relay Systems.
UL Recognized
UL recognized per Standard 508, UL File No. E97033. Note: Output contacts are not UL recognized for
voltages greater than 250 volts and input power supply voltages greater than 150 volts.
GOST-R
GOST-R certified per the relevant standards of Gosstandart of Russia.
Operating Temperature
The operating temperature range is from
−40°C (−40°F) to +70°C (+158°F).
Storage Temperature
The storage temperature range is from
−65°C (−85°F) to +100°C (+212°F).
Shock
In standard tests, the relay has withstood 15 g in each of three mutually perpendicular planes without
structural damage or degradation of performance.
