The dual channel emergency stop safety relay monitors emergency stop devices such as palm buttons and rope cable pulls and positive opening safety switches used for guard gate interlocking it is designed to connect safety devices such as interlock switches to the machine control unit.
For many machine owners, using a software-based safety system isn’t practical. With PSRmultifunction by Phoenix Contact, you can connect up to three safety sensors to a single relay without using any software configuration. It’s as easy as 3, 2, 1, 0: Three redundant inputs; Two of which are independent; One overriding shutdown with Zero programming or configuration.

As industrial machines become increasingly complex and automated, more is being asked of the functional safety systems protecting them. These safety circuits increasingly rely upon multiple guarding technologies working in harmony to provide a high degree of functional safety in the most cost effective manner possible. Let's look at a few examples.
Chaining all safety circuits and series to a single safety relay creates an inexpensive safety circuit but limits functionality and doesn't reach the highest levels of safety with the possibility of fault masking. Taking each safety circuit to it's own individual relay reaches the highest levels of safety but costs more than the previous series chain example. And functionality comes at a cost with more intensive relay logic wiring. Moving the logic circuit to a configurable relay allows for function block based logic to create very flexible systems capable of high level safety solutions. But using a safety processor usually increases prices and software is involved. For many machine owners, using a software based safety system isn't practical. With Phoenix Contact's PSRmultifunction you can connect up to three safety sensors to a single relay without using any software or configuration.
As you can see, each safety sensor is individually wired to the PSRmultifunction relay. Sensors S1 and S2 will function independent of each other. With each input controlling it's own set of redundant contacts and individual reset inputs. Sensor S0 will override both S1 and S2 causing both sets of redundant contacts to deenergize. All of the connections are hard wired with no software or configuration switches needed.
