4.- MODELS
4.1.- MODEL
BDF-XX-T1, TOTALIZER WITH INHIBIT FUNCTION

Counter remains held during all time that the Channel 2 remains connected to 0 Vdc. and runs
free meanwhile Channel 2 is free.
4.2.- MODEL
BDF-XX-T2, TOTALIZER WITH UP/DOWN CONTROL
Pulses per Channel 1. Channel 2 operates as UP/DOWN control.
If Channel 2 is connected to 0 Vdc. then the pulses will subtract.
