Emergency Stop Safety Module

Model ES-GA-5A

for 24V dc/115V ac operation; 

Model ES-HA-5A

for 24V dc /230V ac operation

WARNING . . .

This Emergency Stop Safety Module is not a point-of-operation guarding device, as

defined by OSHA regulations.

It is necessary to install point-of-operation guarding devices, such as safety

light curtains and/or hard guards, to protect personnel from hazardous machinery. 

Failure to install point-of-

operation guards on hazardous machinery can result in a dangerous condition which could lead to serious
injury or death.

!

•  Monitors one dual-channel normally-closed emergency stop switch circuit for a

contact failure or wiring fault

•  Input monitoring circuit uses a diverse-redundant design

•  Four output switching channels for connection to control-reliable power

interrupt circuits

•  Auto reset or monitored manual reset

•  Auxiliary non-safety outputs for status monitoring by process controller: one

electromechanical “hard” contact, plus two solid-state outputs

•  Design complies with standards UL991, EN 418, and EN 954-1

(Safety Category 4)

•  For use in functional stop category 0 applications per NFPA 79 

and EN 418

• 5 amp safety output contacts

• Plug-in terminal blocks
