I need some help identifying something I bought at an auction. In with a bunch of older Modicon PLC modules, I found four new modules that are made for a rack and "2nd Harmonic Grade" is printed on the front. There is a 10vDC meter, on/off switch, "ACPT" LED, "REJ" LED, J1 jack, J2 jack, gnd jack, and a Knobpot Bourns "Level" adjustment knob with an adjustable clock type setting under the top of the knob. The circuit board is marked with the number 0039-8416-9-006-01. This did not come up as a NSN. However, this is at least 15 years old so it could be obsolete. The circuit board has a logo that looks like a backward "K" joined to a lower case "b". Other than the electronic component labels, there are no other markings or name brands. It has 22 wide contacts in back of which 17 are in use. The contacts are side by side on a part of the circuit board for a blade (? term) contact. Here is a link to some pictures of this module.
