The 8T model name flows well in conversation when ordering parts, and it's easy to remember.
Electromatic SC 205 724 Recycler Symmetrical W/ Base 24 VDC 0.15-3 SEC.
I noticed the1618002-8 stamped on the relay, which made cross-checking specs pretty straightforward for me.
What I like most is the timer's ease of use, just dial in the duration and go.
