Pulse adapter on M-Bus line in slave configuration. Twinpulse has a primary address and a secondary address for both inputs, simplifying the management of readings. The converter is powered by the M-Bus network itself.
Twin-Pulse is a pulse counter for metering applications. It is an M-Bus based device and operates in slave configuration. It can manage simultaneously up to two pulse inputs. Twin-Pulse has a single primary address and a single secondary address for both counter inputs for quick installation and easy management of readings. Care must be taken that each input is assigned the correct count line. The two counter inputs are identified as J1 (counter 1) and J2 (counter 2). Twin-Pulse is supplied with power by the M-Bus network. The device can be set up with the MBus Tool software.
