The new EtherMeter adds 1500V galvanic isolation to the meter input channels and 2500V galvanic isolation to the serial ports; and it also boasts improvements to the 1500Vrms galvanic isolation of the Ethernet port, as well ⚊ all of which increases resilience against transient voltage events.
The most modern component technology was also leveraged, which led to an approximate 25% reduction in power consumption. Reduced power consumption will especially benefit solar-powered applications. The typical power consumption of the new EtherMeter is approximately 1.5W.
The firmware is virtually identical to that flashed into the v.256 EtherMeter. For this reason, the Serial/Telnet Setup Procedures (HyperTerminal, PuTTY) are virtually unchanged. However, the dip switch definitions were necessarily modified to a minor extent. Please review the User Manual for details.
For customers who utilize the EtherMeter as a “mini-RTU” for metering and valve stations, the v.257 EtherMeter provides a convenient, integrated 24VDC loop power source at terminal.05 (previously unused), which can be used to power one or two 4-20mA or 0-5V pressure transmitters.
The v.257 EtherMeter also provides a “factory-reset” button. When the reset button is depressed during a power-cycle or reboot, all user-settings are discarded and replaced with factory defaults.
