Digital Inputs IN_1, IN_2, IN_3 

The  eight  pin  connector  of  the  TMCM-1140  provides  three  multipurpose  digital  inputs  IN_1,  IN_2  and 
IN_3. 
 
All three inputs accept up-to +24V input signals. They are protected against these higher  voltages using 
voltage resistor dividers together with limiting diodes against voltages below 0V (GND) and above +3.3V 
DC (see figure below).

Refer to the PD-1140 TMCL Firmware Manual (SIO command) for further information about switching the 
pull-up resistors for all digital inputs on / off.  
 
The  three  digital  inputs  have  alternate  functionality  depending  on  configuration  in  software.  The 
following functions are available:
