BC120 series Heidenhain Monitor, with a Heidenhain system number of 31303702 is a late TNC4xx generation Heidenhain monitor, that was fitted on the Heidenhain system series TNC 425, 426, 430 controls. The original is a 15″ CRT colour display (farbe / color). The replacement for this is aptly named the DNC120 which is an equivalent LCD TFT replacement monitor for the Heidenhain BC120B monitor, and will physically and electronically work in all Heidenhain controls, that were originally fitted with the BC-120B. The DNC120 retails @ POA, plus any additional charges, such as shipping. The DNC monitor is available now, and ready to ship anywhere in the world.
