Holosys M-Bus PulseReader Px is a device for two (P2 device) or four (P4 device) independent meters (water, gas, heat, electricity) readouts in accordance with EN 13757-2, EN 13757-3, and EN 1434-3 standards.
Holosys M-Bus PulseReader is represented as two (P2 device) or four (P4 device) independent M-Bus slave devices in the M-Bus system.
For each of the M-Bus slave devices presented by the PulseReader, the user can assign one primary and one secondary address. Support for secondary addressing makes the device suitable for implementation in M-Bus systems with more than 250 M-Bus slaves.
The device is equipped with due date meter reading function. Meter readout data are stored separately for each input on the date defined by the user. Thereby it is easy to track the consumption of a certain utility meter.
Holosys M-Bus PulseReader has an integrated support for systems with two different tariffs. In such operating mode, one of the inputs for non-voltage contacts is used for pulse counting while the other input is used for tariff switching. Model P2 supports one, and P4 two dual-tariff meters.
In case of power supply or M-Bus failure, the device is equipped with an internal battery. The device monitors power supply voltage levels and in case of power loss on the bus, the device automatically switches to battery power to ensure the continuity of pulse counting and data integrity. The device also saves the data on a daily basis into non-volatile memory in case of battery discharge.
