MCE18 stands for “Multifunction Can Bus Extension” with previously 18 connections (now 19).
 
– why is this module needed?

Canchecked displays ( MFD15 , MFD28 , MFD32 ,  MFD32S ) have four analog inputs. However, for some applications this may be too little and more inputs are required.
 
It makes sense to map this using the flexible Can Bus protocol. For this purpose, the sensors are connected to our MCE18 and sent via Can Bus to the device to be received – for example one of canchecked displays.
 
But even freely programmable control devices only have a limited number of inputs. This can be easily expanded with our module and sent directly to the control unit.
9 analog inputs (0-5V)
8 digital inputs (on/off)
3 digital outputs (on/off LOW SIDE 0.5A) (new in v2!)
