Reviews For 489-P5-HI-A20-E

Internal Review
(4.0)

The 489-P5-HI-A20-E is housed in a metal and plastic chassis; the plastic latch is particularly brittle and prone to breaking if too much pressure is applied. Users should take particular care if the components don't attach or interact smoothly with one another. However, this is a larger problem with Multilin as a whole and no extra worry should be had while using this unit as your main interface. Additionally, this relay has high demand and very limited availability on the market as of 2023. - AX Control Technician
