Unfortunately TKE considers the LMH obsolete now. The IDEC PLC is no longer supported by IDEC and they do not manufacture the modules or power supply anymore. Vertical express(TKE parts) did have some remaining stock on the modules and some other parts a year or 2 ago when I needed an output module, but I was told after their stock is gone they have no way of replacing it. They are telling all their customers who have the LMH and the LMT(traction) controls to look at modernization as they don't plan on supporting this product anymore.
So you may want to suggest that your customer look at modernization as well just due to parts issue with these controls. But I will say the LMHs I have maintained have been very reliable for the most part, it just comes down to that one day you will need parts.
