Power Relay G7L

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

No contact chattering for momentary voltage drops
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, and DIN
track mounting available.

Precautions

Refer to page NO TAG for general precautions.

Handling

!

To preserve performance, do not drop orotherwise subject the
Power Relay to shock.

!

Thecaseis notdesignedto beremovedduring normalhandling
and operation. Doing so may affect performance.

!

Use the Power Relay in a dry environment free from excessive
dust, SO

2,H2

S, or organic gas.

!

Do notallowa voltage greater thanthemaximum 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-equipped Relays weighapproximately100g. 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-connectterminalscanbeconnectedtoFastonreceptacle
#250 and positive-lock connectors.

!

Allowsuitableslackonleadswhenwiring, anddo notsubject the
terminals to excessiveforce.

Cleaning PCB Terminals

!

PCB terminals have flux-tight construction which prevents flux
from penetrating into the Relay base housing, e.g., due to
capillaryactionupthe terminalswhenRelay issolderedonto the
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.

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%ripplemust beused forthe operatingvoltagefor
DC Relays. Before using arectifiedACsupply, confirm that the
rippleisnotgreaterthan 5%.Ripple greaterthanthis canleadto
variations in the operating and reset voltages.

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