Removable terminal block
enables easy replacement

The terminals can be attached and
removed easily with a at screwdriver
allowing easy replacement of the
module.

The terminal cover detects
improper connection

The terminal cover does not close if
the terminal is not fully inserted into
the module.

Simple wiring procedure

No complex work required. Just insert a
ferrule into the terminal. The wire is locked
into the spring terminal so a screwdriver is not
required when inserting the wire.

Insert

No tools needed.
Directly insert a
ferrule into the terminal.
The wire is locked.

Removal

Insert a at
screwdriver
into the terminal
entrance.

Note 1: UL and CSA are approved by TÜV SÜD America Inc., an accredited

NRTL.

Note 2: HR2S-301N is recommended for use in category 4 safety

applications. The requirements of the safety category must be
determined according to the safety equipment. We recommend that
you consult a third party organization.
Categories may change depending on the combination of the safety
equipment. Categories may also change depending on the output

contact ratings.
Note 3: Measured using 5 or 6V DC, 1A voltage drop method.
Note 4: When measured at the rated voltage (at 20°C), excluding contact

bounce time.
Note 5: The time from when the safety input turns OFF to when the safety

output turns OFF.
Note 6: Leave 5 mm of space between the sides of the module when more

than 3A is continuously applied to the relay contact.
Note 7: The module is not suitable for use with a load less than the

minimum applicable load. Once a large load is applied, contacts

may not operate with a small load.
Note 8: The maximum current of the safety output contact is specied by

the approved standard.

Category 3 HR2S-301P 5.0A

•To prevent the safety output contact from overcurrent, use a fuse. To satisfy

Category 4, use a fuse with a maximum current of 3.6A. This fuse is not
required if the short circuit current is less than 5A.
