Module RS485/RS232 with integrated memory for WM series

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 to 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.

Main Benefits

• Clarity. The wide backlit LCD display clearly shows the measurements and the configuration parameter values.
• Simplicity. The rotating pages function automatically shows all measurements in sequence without having to use the keypad. An optical port is available for quick analyzer configuration using OptoProg (CARLO GAVAZZI).
• Specific software. WM20 can be configured and measurements viewed from UCS configuration software (CARLO GAVAZZI). The software and subsequent updates are free.
• Scalability. Two accessory modules can be added to WM20 according 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. WM20 and accessory modules are all equipped with detachable terminals. Modules can be quickly installed via the specifically designed fast coupling pins.
• Tamper-proof. WM20 configuration access can be locked. Terminals and accessory modules can be sealed.

Main functions

• Measure main electrical variables and voltage and current harmonic distortions
• Measure active and reactive energy
• Measure load operating hours
• Manage up to 16 alarms
• Manage up to 8 digital outputs (via optional accessory modules)
• Manage up to 6 digital inputs (via optional accessory modules)
• Manage temperature, process signal and real neutral current (via optional accessory module)
• Manage up to 4 analogue outputs (via optional accessory modules)
• Manage process signal, temperature and real neutral current input (via optional accessory module)
• Transmit data to other systems (via optional accessory module)

Applications

WM40 can be installed in any switchboard to control energy consumption, main electrical variables and harmonic distortion. In automation, WM40can use the communication module with Profibus protocol to both communicate data on consumption to supervision systems and manage them independently if installed on a machine. In building, WM40can be installed in existent architectures using the communication module with BACnet protocol (on RS485 or Ethernet).
