Power Relay G7L

A High-capacity,
High-dielectric-strength Relay
Compatible with Momentary Voltage
Drops

No contact chattering for momentary voltagedrops
up to 50% of rated voltage.

Wide-range AC-activated coil that handles 100 to
120 or 200 to 240 VAC at either 50 or 60 Hz.

Miniature hinge for maximum switching power,
particularly for inductive loads.

Flame-resistance materials (UL94V-0-qualifying)
used for all insulation material.

Quick-connect, screw,andPCBterminals,andDIN
track mounting available.

Precautions

Refer to page NO TAG for general precautions.

Handling

To preserve performance, do not drop or otherwise subject the

!

Power Relay to shock.
Thecase is notdesigned to be removed during normal handling

!

and operation. Doing so may affect performance.
Use the Power Relay in a dry environment free from excessive

!

dust, SO
Do not allow a voltage greater than the maximum allowable coil

!

voltage to be applied continuously.
Do not use the Power Relay outside of specified voltages and

!

currents.
Do not allow the ambient operating temperature to exceed the

!

specified limit.

Installation

Although there are not specific limits on the installation site, it

!

should be as dry and dust-free as possible.
PCB Terminal-equippedRelays weigh approximately 100 g. Be

!

sure that the PCB is strong enough to support them. We
recommend dual-side through-hole PCBs to reduce solder
cracking from heat stress.

Quick-connectterminals canbeconnectedtoFastonreceptacle

!

#250 and positive-lock connectors.
Allowsuitableslack onleadswhenwiring,anddonot subjectthe

!

terminals to excessive force.

Cleaning PCB Terminals

PCB terminals have flux-tight construction which prevents flux

!

from penetrating into the Relay base housing, e.g., due to
capillaryactionuptheterminals whenRelayis solderedontothe
PCB. This type of Relay cannot be immersed for cleaning.

Connecting

Refer to the following table when connecting a wire with a

!

crimp-style terminal to the G7L.

Terminals

Coil

Contact

Rated Current Flow

When using B-series (screw) products, the rated current from the
screw terminals (M4) should be 20 A or less according to jet stan­dard (electrical appliance and material control law of Japan).

Operating Coil

As a rule, either a DC battery or a DC power supply with a

maximumof5%ripplemustbeusedfortheoperatingvoltagefor
DC Relays. Before using a rectified AC supply,confirm that the
rippleisnot greater than 5%. Ripplegreaterthan this can leadto
variations in the operating and reset voltages.

As excessive ripple can generate pulses, the insertion of a
smoothing capacitor is recommended as shown below.

DIN Track Mounting

Use a DIN-conforming 50-cm track or 1-m track (both are sold
