Siemens have released the SENTRON PAC4200 multifunction power monitoring device which is an addition to their power management products. The SENTRON PAC4200 joins the existing SENTRON PAC3200 multifunction power monitoring device, offering enhanced features and a high level of specification.
Suitable for use in Modbus RS465 and Profibus DP networks, the SENTRON PAC4200 multifunction power monitoring device offers a standard Ethernet port with a transmission rate of 100Mbit/sec with built in Modbus gateway, enabling it to be used as a master to monitor up to 32 sub devices without a repeater.
The SENTRON PAC series features an easy to read back lit screen. The new SENTRON PAC-4200 multifunction power monitoring device incorporates high levels of visibility and display capabilities and is easily configured to visually show specific values, displayed in either two or four parameters, that can be shown in a combination of either bar graph or printed values.
The SENTRON PAC4200 multifunction power monitoring device can monitor up to 200 values, with 12 limits available for setting over-range and undershoot. The SENTRON PAC4200 multifunction power monitoring device is supplied standard with two digital inputs and two digital outputs to ensure set limits are maintained, enabling the setting of alarms or limit value signalling. Further I/Os can also be added through an optional DI/DO expansion module.
Harmonics can be damaging in electronic devices, as excessive harmonic levels in the odd multiples (3rd, 9th and 15th) can build up in the neutral phase. As the neutral phase is not often dimensioned to carry these currents, this can cause overheating and resultant damage and failure within electronic circuits. A development feature of the SENTRON PAC4200 multifunction power monitoring device is its capability to measure and monitor these harmful harmonics up to the 31st harmonic for voltage and current, enabling accurate RMS measurement, which makes it useful for monitoring power quality.
For transparency in processing and comprehensive cost centre value detection of the measured data, the SENTRON PAC multifunction power monitoring device is easily integrated into advanced automation and power management systems.
Siemens SIMATIC Powerrate power management software packages are available to suit process and control networks, and when combined with the SENTRON PAC monitoring devices, provide better energy management systems.
