Beckhoff KL3062

Here is the inside of a Beckhoff KL3062, 2 channel, 12 bit, 0-10 V input module.

Well designed multi layer PCB.

KL is the “older” series of Beckhoff’s I/O modules, it incorporates the K-bus connection interface, which is basically an INTERBUS interface, but Beckhoff names it K-Bus (Koppler-Bus).

The main ICs are shown in the picture below.

The microcontroller is a PIC16F something, running at 16 MHz.

The back side of the PCB couldn’t be shown, because it was assembled once and there’s no way to disassemble without desoldering one of the LEDs.

On the back side there is only one bigger (44 pins) IC named Beckhoff BK200A. This must be the INTERBUS protocol IC, just named in a “Beckhoff way”.
