Pulse adapter to acquire pulses coming from n. 2 meters with pulse output (both REED and NAMUR). Transmission of consumption data via M-Bus to the OZW10 central unit. All types of pulse meters can be connected: water‚ gas‚ electricity‚ heat etc. The adapter must be configured via software to define the weight/pulse of the meters connected. Battery life: 12 years. Electronic output (Open Collector, Open Drain): Residual voltage once switched < 0.7 V, Maximum frequency < 17 Hz, Minimum pulse duration 30ms. Mechanical switching (Reed contact, relays): Bounce time < 1 ms, Maximum frequency < 2 Hz, Minimum pulse duration 260ms.
