How To Install Integrity Series INT-04 Emergency-Stop Safety Relay Applies to the following part numbers and more: INT-04-024 INT-04-120 Description The Sentrol INT-04 Series Emergency-Stop (E-Stop) Safety Relays are designed for use as part of a safety circuit in emergency-stop  or safety floor mat sensing applications. Each is a safety relay that uses positive-guided relays, configured for self-checking, to inhibit machine restart in case of internal component failure. The GE S …

How To Install GuardSwitch Series 391-BT and 393-BT Safety Interlock Switch Description The GuardSwitch Series 300 Safety Interlock Switch, models 391-BT and 393-BT DPST (double pole single throw) are designed for use with safety monitored relays or monitored circuits. To achieve the optimum defeat resistance features of the switch, both the switch circuit (Circuit 1) and the tamper circuit (Circuit 2) must be connected. An optional third circuit can be provided to indicate at the panel w …

How To Install Integrity Series INT-03 Monitor Relay Description The INT-03-024 or INT-03-120 Safety Monitor Relay is intended for use as a part of a safety circuit in guard interlock applications. It is a safety relay which uses positive guided relays, configured for self- checking, to inhibit machine start-up in the event of an internal component failure. Both normally-open and normally-closed inputs are required. Multiple NO contacts can be wired in series while multiple NC contacts …
