This device converts impulse outputs of older meters to data accessible via M-Bus. Each PDImp can be connected to 2 impulse meters; the connected meters are configured separately. The unit has two integrated relay outputs that can automatically control contact switches and control consumption so they do not exceed 15 min maximum. The bus unit acts as a 4-node node. This abstraction allows for complete module setup. The module can be connected to an existing ModBUS network and also use third-party SW tools. It is also possible to supply a PDMAX unit equipped with a single channel to capture a 15-minute pulse from the billing electrometer.
