Description of MD Series
The MD (Totalizer) Series is a 4 digits LED Totalizer in a DIN 72 x 72 panel size (Panel Cut-out size: 68 x 68mm). This is a very simple but functional totalizer. With a counting speed of 1kHz maximum, this Add only counter accepts Contact or Non-Contact pulse input. You can power the MD (Totalizer) Series using either AC100/110V or AC200/220V, based on your choice. Additionally, it offers an external DC12V power supply specifically for sensors. On its front panel, there’s a reset button. But if you prefer, there are also options for remote or electrical reset. Memory is optional.

Rear Terminals And Wiring
Attention
1. Do not feed a voltage signal into the Contact Input terminals. This may cause damage to the input circuit of the unit.
2. Use shielded lead wires for the Input terminal and Reset terminal. Also, make the lines from the power source as far as possible from the lines of the Input and Reset lines.
3. For MD-040M model (with memory type), make sure to short terminals 7 and 8 to enable the memory function.If you plan to turn off the counter for an extended duration, make sure to disconnect terminals 7 and 8. This step helps in preserving the internal battery’s charge. Whenever you power up the counter, it charges this internal battery.
Connection
Application
Metal Stamp Machine / Various Machine.
Machine usage monitoring by counting the units produced is necessary to maximize investment and profitability. The counter will start to increment every stroke made by the machine. Stroke can be set either going UP or DOWN.
Printing Machines / Photocopiers
Counters can be used for counting the number of sheets or papers in printing machines or photocopiers.
Product Counting
Counters can be used for counting, sorting and packaging various products.
