* four independent counters
* overall results in the FLOAT (floating) values â€‹â€‹ for hours and INT (integer) broken down into seconds, minutes, hours, days (4 registers per counter).
* counter input designed to work with AC/DC signals
* factor adjustment (a floating-point value)
* selecting a mode of state 1 trigger: with high or low voltage
* time filter that allows you to limit the maximum length of the input signal (to eliminate interferences on the input of the counter)
* memory of counter status after power failure
* digital input
The MB-LG-4 module is a four-channel one-way counter. Each channel is independent and counts the time in accordance with individual settings. The result is presented in the form of a floating-point number, and in parallel as integer values â€‹â€‹broken down into components in the form of days, hours, minutes and seconds.
The counter has a software function that allows to reset the counter of each channel independently. Maximum time is approx. 150 years. After reaching the maximum number (overflow), the counter automatically resets itself and starts counting from 0. The module has configurable options of counting with low (0V) or high (V +) signal and the closing or opening of the input signal circuit. Counter allows to set the minimum length of input signal time, which will be seen at the input and will be treated as an activation of the input (time filter). Shorter signals are ignored. This is used for correcting the interference (false pulses) that may appear on the input. Counting input can be used as a DI digital input with the ability to read its state.
Reading of the counter can be reset independently for each channel. Once the maximum number of pulses (overflow) is reached, counter automatically resets and counts from 0. The module has configurable options of counting pulses with low (0V) or high (V+) signal and with leading or trailing edge.
Reading the counted values, adjustment of all counting parameters, communication and data exchange is carried out via RS-485 port using MODBUS RTU communication protocol. Power is indicated by a green LED U light. Correct data exchange between the module and other device is indicated by the LED yellow Tx light.
