steverino pussycat (Customer) asked a question.
I understand supply chain problems. I understand the AD-SSR810-DC-28Z is discontinued. I appreciate the fact AD has a replacement. What really grinds my gears :-) is the replacement requires you to run a coil wire and a load wire all the way around the panel through the ducting so the power can come in from OPPOSITE sides of the relay. Most puck SSR's come in from the same side, like the obsoleted AD SSR's, so that would be a possibility if they didn't take up so much real estate. What I would really like to ask is, "what were the Gelfran engineers thinking," but I'll limit my question to "what is the recommended routing to get the power wires where they need to go and how do I come in from opposite sides with the shielded coil wire?"
I see my own answer, I can run extend the wire down through the heat sink so I don't have to take a circuitous (pardon the pun) route around the block through the wire ducting. It was irritating enough when the GS1 was obsoleted and now all the power goes in and out through the bottom of the drive.
I can't understand why replacement components force field changes that require lengthening and/or re-routing wires. Most engineers spend some brain power keeping low Voltage signals away from high Voltage loads, and component designers don't give it a moment's throught.
It's the same issue with power supplies, The Rhino selection does the wiring opposite and my techs asked us to stop buying them. We've gone to IDEC to make them happy.
As far as the drives go, Allen-Bradley has the wires for power, safety, networking and I/O all enter from the bottom. This might be a situation of "following the leader."
We just tried out an SSR where the coil wire lands on the top, on opposite sides of the relay. The shielded coil wire is hanging in mid-air with no support. It is hideous, and I'm not doing it. F that.
The AD-SSR810-DC-28Z was a great solution. Inexpensive, the PLC fires it directly, zero cross, LED indication, shielded wires on opposite side of the load . . .
It was a good solution to many problems. I'm going to try this:

Not as pretty as the AD-SSR810, but functional. I like the AD because the wires fly in low out of the ducting.
