For sale is a Durant "Ambassador" Series, Model No.57601-401 Single Preset Count Control with Rate. 1/60/115VAC Input power. Serial communications port. Rate meter. (1) Form "C" relay. NOTE: I removed this Durant Count Control from a working, custom machine that was in use at a local manufacturing plant that has been closed-down. * CONDITION NOTE *: This unit has damage to the display (see the photographs). It powers-up, and appears to be functional, but is being sold on an "as is" basis - what you see, is what you will get. But we did plug it in to test.
