WM50 and TCD12
Introduction
Description
WM50 is a multichannel power analyzer for single, two and three-phase systems. Using TCD12 split core current sensors, it can monitor up
to 96 single-phase loads or any combination of single and three-phase loads or two and single-phase loads for a maximum of 96 channels.
The system can be set up, measurements viewed and up to 16 alarms managed from WM50 and UCS. Main unit functions can be expanded
with a maximum of two of the following available modules: digital input/output module, analog input module and communication module.

Components
Component Description
WM50 Main unit, measures and displays the main line electrical variables via current sensors. With LCD display and touch keypad, it
lets you set measurements parameters, configure accessory modules and manage up to 16 alarms. It communicates with TCD12
current sensors via pre-installed MABC module to monitor up to 96 channels.
Accessory modules
(optional)
Connected to the main unit via local bus, the following expand WM50 functions:
Type Module description Part number
Digital inputs/outputs Six digital inputs and six static outputs M F I6 O6
Six digital inputs and four relay outputs M F I6 R4
Analog inputs Three analog inputs (neutral current, temperature probe, 20 mA input) M A TPN
Communication Modbus RTU communication on RS485/RS232 M C 485 232
Modbus TCP/IP communication on Ethernet M C ETH
TCD12 12-channel current sensor. Measures main electrical variables on the single channels and loads and transmits them to WM50. A
maximum of eight TCD12s can be connected in series on two TCD buses to each WM50 via TCD12WS cables.
UCS Configuration and diagnostics software. Available for both PC and Android mobile devices.
OptoProg (optional) Optical communication interface to configure the analyzer and TCD12s or to read data in real-time from PC or mobile devices via
UCS.
Master Modbus
(optional)
Supervision system for WM50 data analysis and monitoring.
