G2RL  

PCB Power Relay  

Low profile power relay  

with 15.7 mm height, ideal for  

incorporation in miniature  

equipments  

• A wide variety of single pole, double pole, high-capacity (16 A)  

type and high-sensitivity type (250 mW) relays are available.  

• IEC/EN 60335-1 conformed. (-HA Model)  

• Satisfies ambient operating temperature requirement of 85°C  

and 105°C (-CV Model).  

• Clearance and creepage distance: 8 mm / 8 mm min.  

• G2RL-1(A)-E-ASI: TV3 rating models available.  

• IEC/EN 60079-15 conformed  

(Except G2RL-1(A)-H, G2RL-1A-E-CV(-HA) Models).  

• Reduced power consumption with voltage holding and pulse  

width modulation (PWM) control (only for G2RL-

@

-PW1 model).

Precautions  

• Please refer to “PCB Relays Common Precautions” for correct use.  

Correct Use  

●

Mounting Position Compared to G2R Model  

●

Power consumption reduction of coil with pulse width  

modulation (PWM)  

• Although the G2RL model and the G2R model are both low  

profile relays, their characteristics such as switching capacity  

are different. Be sure to check operation under the actual  

operating conditions before use.  

• Models with PWM drive capability (-PW1) can reduce coil  

holding current with PWM control. This function reduces power  

consumption by reducing the current held by coil.  

• Apply the rated voltage for at least 100 ms at the time of relay  

operation.  

• The following are our verification conditions. When using, it be  

sure to check the actual machine under the actual usage  

conditions.  

●

Cleaning  

• The G2RL model is flux-resistant with two sealing holes on the  

case. Thus, do not clean the relay by boiling or soaking in  

water. Consult your Omron sales representative for sealed  

type rela

y

.  

●

Using Relays in an Atmosphere Containing Corrosive  

Gas  

• Do not use relays in an atmosphere containing corrosive gas  

(sulfuric or organic gas). Otherwise, connection failure due to  

corrosion on the contact surface may lead to functional faults.

Operation  

• If the coil voltage is reduced to the holding voltage after relay  

operation, first apply the rated voltage to the coil for at least  

100 ms, as shown below.

• A voltage of at least 55% of the rated voltage is required for the
