A1SD61

The A1SD61 counter module is a high-speed counter module that was designed by Mitsubishi Electric as part of the MELSEC A series. It was designed to count pulses for Mitsubishi MELSEC A series CPU modules. The A1SD61 high-speed counter module can count 1-phase pulse inputs and 2-phase pulse inputs. It can support a maximum pulse counting speed of 10kpps or 50kpps, and the users can set its maximum pulse counting speed with a selection pin. Multiple A1SD61 high-speed counter modules can be connected to the same CPU module as long as the number of I/O points on the CPU module is not exceeded. The A1SD61 high-speed counter module occupies 32 I/O points when it is installed. This module can support voltage signal levels of 5 Volts DC, 12 Volts DC, or 24 Volts DC, and it can support current signal levels of 2 to 5 mA. The A1SD61 high-speed counter module can support a 32-bit signed binary counting range and a 32-bit signed binary comparison range. Its internal power consumption rating is 0.35 Amps at 5 Volts DC. The A1SD61 high-speed counter module has 1 channel. This module is designed to be installed inside the control panel in a programmable controller system. It can operate at 0 to 55 degrees Celsius with 10 to 90% non-condensing relative humidity levels. This module can also be stored at -20 to 75 degrees Celsius with 10 to 90% non-condensing relative humidity levels. The A1SD61 high-speed counter module supports several functions, including a preset function, a ring counter function, a limit switch output function, and a variety of selectable counter functions.
