Timer with MODBUS RTU output, 4-channel, 1 module 160÷265V AC/DC
Functions:
- 4 independent counters
- total results in FLOAT (floating-point) values for hours and INT (integer) in the breakdown of the result into seconds, minutes, hours, days (4 registers per counter)
- counter input suitable for operation with AC/DC signals
- choice of state 1 triggering option: high or low voltage level
- time filter, allowing to limit the maximum length of the input signal (elimination of interference at the counter input)
- memory of the counter status after power supply voltage loss
- digital input function
Operation:
MB-LG-4 timer is a 4-channel unidirectional counter. Each channel is independent and counts operating time according to individual settings. The result is presented as a floating point number and in parallel as integer values broken down into components in the form of days, hours, minutes and seconds. The counter has a software function to reset the counter status of each channel independently. The maximum time is about 150 years. When the maximum number is reached (overflow), the counter automatically resets and counts from 0. The module has configurable options for counting with a low (0V) or high (V+) signal and closing or opening the input signal circuit. The counter has the ability to set the minimum length of time an input signal will be seen at the input and treated as an input activation (time filter). Shorter signals are ignored. This is done to eliminate interference (false pulses) that may occur at the input.
The counting input can be used as a digital DI input with the ability to read its state.
Reading of counted values, setting of all counting parameters, communication and data exchange are realized through the RS-485 port using the MODBUS RTU communication protocol. Switching on the power supply voltage is signaled by the lighting of the green U LED. Correct data exchange between the module and the other device is signaled by the illumination of the yellow LED Tx.
