The PowerLogic PM8144 is an ION meter designed for DIN rail installation in low and medium voltage applications, featuring a remote display for front mounting (96 x 96 mm) and AC/DC control voltage. It has been developed to ensure the availability and efficiency of your energy-critical installations. With modular, flexible, and powerful ION technology, custom applications can be created for each meter. It offers high accuracy, multiple communication ports, a web-based user interface, and a graphical color display. Certified by independent laboratories for class 0.2S accuracy in active energy. Cybersecurity features include secure protocols, logging of security events, and Syslog logging. There is the option to enable/disable communication ports and support for 50 configurable user accounts to manage access. It comes with 64 MB of memory to support up to 10 data logs, 50+ customizable alarms, waveform capture with up to 128 samples/cycle, and 1/2-cycle RMS logging. The memory can also be used for custom web pages, Min/Max logs, energy trends, and operating hours. Event timestamps are accurate to +/-1ms using time synchronization. Time synchronization methods include PTP, NTP, IRIG-B, GPS ASCII, and network time setting functionality. It has 3 digital inputs and 1 digital output, as well as the ability to add up to 4 option modules. The input/output option modules include 2 relays and 6 digital inputs or 2 analog outputs and 4 analog inputs. It operates with a wide control voltage range of 90-415 VAC / 110-415 VDC. The operating environment ranges from -25 to +70°C, with humidity from 5% to 95% and an operating altitude of up to 3000 m.
