Acromag 1762-Y-TV-3 Signal Selector This unit was purchased from a large business inventory reduction sale. I do not know the history of it. It is also marked, "Input A, B, C, : 4-20MA, 250 Ohm, Output 1-5VDC, Power 24VDC". It has a lot of other information on the label and there is a close-up of it in the pictures. I am not able to test it. It only comes with what is shown in the pictures. S548-5 d rl fdk 80816228
