6ES5262-8MA12 - High Speed Counter - SIEMENS

The module consists of two independent down counters with isolated inputs and outputs.
It counts input signals up to a frequency of 500 Hz from a set value down to the value ”0”. When zero is reached, the 24-V DC output of the module is energized.

At the same time, a green LED on the module lights up and the input signal (I x.0 or I x.1) is set to ”1”.

The setpoint (0 to 999) can be entered via the three-digit thumbwheel switches on the front panel of the module.

The input voltage ranges can be set for 5 V DC or 24 V DC on rocker switches on the front panel.

A counter module can be addressed like a two-channel digital module (channel ”0” or ”1”). For enabling and resetting the counter, you address the module like a digital output module.The counter reading is scanned in the same way as a digital input module.

A counter module is plugged into slot 2. A value of 100 is set on channel ”0” of this module via the three-digit thumbwheel switches.
The incoming pulses are counted once the counter has beenenabled by the control program. As soon as 100 pulses have been counted, a signal (output 4.0) is released.
