12 VDC	170 mA		65 Ω	85 mA		125 Ω
24 VDC	85 mA		270 Ω	50 mA		460 Ω
48 VDC	44 mA		1,050 Ω	24 mA		1,900 Ω

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%, –20%
for AC rated current and ±15% for DC coil resistance.
2. The AC coil resistance values are for reference only.
3. Performance characteristics data are measured at a coil temperature of 23°C.
4. The rated current of the AC operating coil is half-wave rectified current and is measured with a DC ammeter.
5. The peak reverse-breakdown voltage of the built-in diode is 1,000V.
6. The set coil of the Relay rated at 6 VDC is of the 5-minute rating. However, when it is used by connecting a diode
is series, it can be of the continuous rating.
7. By connecting an external resistor to each of the set and reset coils as shown in the table below, the rated current
of the Relay can be increased.
8. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.

Rated voltage	Connected coil voltage	External resistor
		Set coil		Reset coil
		Resistance	Capacity	Resistance	Capacity
110 VAC	100 VAC	0.27 kΩ	0.5 W min.	0.39 kΩ	1/4 W min.
200 VAC	100 VAC	2.7 kΩ	5 W min.	8.2 kΩ	3 W min.
220 VAC	100 VAC	3.3 kΩ	6 W min.	9.1 kΩ	3 W min.
100 VDC	48 VDC	1.1 kΩ	10 W min.	2.0 kΩ	6 W min.

Note: Use a resistor having the above resistance value with tolerances of ±10% for external connection.

Method of Connection

Reset side

Set side
DC coil: Connect terminal No. 14 to terminal No. 12 or No. 14 to No. 8.
AC coil: Connect terminal No. 14 to terminal No. 8.

Note: 1. The data shown above are initial values.
2. The contact resistance was measured with 0.1 A at 5 VDC using the fall-of-potential method.
3. The set or reset time was measured with the rated voltage imposed with any contact bounce ignored at an
ambient temperature of 23°C.
4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used
for checking the dielectric strength.
5. The electrical endurance was measured at an ambient temperature of 23°C.
6. This value was measured at a switching frequency of 60 operations per minute.
