Hi,
We have been asked to specify a remote E-stop solution for a client.
They have 2 sites (so far) and each site has a main control room with 3 Hard wired E-Stops (Mushroom Buttons) located next to the operator's desk. The E-Stops are wired to 3 separate safety PLC's for tripping the respective system.
The plan is to centralize control of the 2 sites at a remote location (Central Control Room) so we need to provide these 3 E-Stops (6 Total) at the new control room.
Not being too familiar with safety systems, I was curious about what other people have done for this scenario.
The plan so far is to simply 'cut in' to the E-Stop circuits and install Remote IO with Relay outputs, then install a PLC at the Central Control Room with new mushroom buttons connected to DI's.
I was thinking of a GuardLogix PLC in the control room with Safety Guard Point IO on site but I'm wondering if we could just use a programmable safety relay - I can't determine from what I've read whether the safety relay is intended to be used in this way e.g Remote IO.
This all seems quite complex for simply switching 3 relays remotely - if anyone has a simpler solution then I'd be keen to hear that too.
Thanks
