WM40 Power analyzer for three-phase systems Benefits Description WM40 is a modular power analyzer for single-, two- and three-phase systems. It is made up of a maximum of four components: the main unit that displays measurements on the LCD display and manages 16 alarms, and three accessory modules, one with digital outputs or analogue outputs, one with analogue outputs, digital inputs and outputs or analogue inputs and the other for communication. The digital output module associates alarms with static or relay outputs and/or transmits pulses proportional to energy consumption. The analogue output module associates 0-20mA or 0-10 V outputs to measured variables. The digital input/output module allows alarm or pulse transmission via digital outputs, tariff management, pulse counting or DMD synchronization via digital inputs. The analogue input module allows temperature, process signal and real neutral current monitoring. The communication module allows you configure the analyzer and transmit data using a different communication protocol according to the version and, if equipped with memory on board, permits log of data and events. 16/05/2022 WM40 DS ENG • Clarity. The wide backlit LCD display clearly shows the measurements and the configuration parameter values. • Simplicity. An optical port is available for quick analyzer configuration using OptoProg (CARLO GAVAZZI). • Specific software. WM40can be configured and measurements viewed from UCS configuration software (CARLO GAVAZZI). The software and subsequent updates are free. • Scalability. Three accessory modules can be added to WM40according to need. This way, the analyzer extends its control capacities and communicates data remotely. • Communication flexibility. The communication module is available in Modbus RTU, Modbus TCP/IP, BACnet IP, BACnet MS/TP and Profibus DP V0 versions. • Fast installation. WM40and accessory modules are all equipped with detachable terminals. Modules can be quickly installed via the specifically designed fast coupling pins. • Tamper-proof. WM40configuration access can be locked. Terminals and accessory modules can be sealed.

CARLO GAVAZZI Controls SpA 33 Digital input/output modules Main features • 6 digital inputs • 4 relay outputs or 6 static outputs • Configuration via main unit keypad or UCS configuration software • Easy mounting on main unit • Detachable terminals • Local bus connection to main unit Main functions Description Accessory module for WM analyzer family with digital outputs for alarm or pulses transmission and digital outputs for tariff management, DMD synchronization and pulse counting. Each output can run three different functions: alarm, remote control or pulse. Digital inputs can run four different functions: tariff management, remote control, pulse counting (positive/negative active energy, reactive energy, protection trip, water/gas/heating) or remote alarm reset. 16/05/2022 WM40 DS ENG • Transmit pulses with frequency proportional to energy consumption • Associate alarms to static or relay outputs • Remote output control • Tariff management • Pulse counting • Remote alarm reset CARLO GAVAZZI Controls SpA 34 Digital input/output modules Structure Part Description A Detachable terminal block for inputs/outputs or area specific to communication ports B Fastening pins to main unit or other accessory module C Internal local bus port for communications with main unit or other accessory module D External local bus port for communication with communication module.
