Host Engineering currently does not have any HMI products. JTEKT (Koyo) develops and manufactures those. We have no plans to develop an exact drop-in replacement.
Sometimes they offer "lifetime buys", but that is not a great answer. On their website, I see that their recommendation is a CM5 model, but the mounting is not compatible - that's not good either.
I recommend you post something on Automation Direct's Community forum - you are definitely not the only customer dealing with this.
