RMS 621 Energy Manager Datasheet

Up to three different applications per device can be processed simultaneously. Two separate counters are available for each application, each of them is resettable.

Connection of measured variables 0/4 to 20 mA, PFM or pulse for sensors such as flow (differential pressure probes, vortex, turbine, orifice plate, among others) or pressure. When measuring temperatures, Pt100, Pt500 and Pt1000 in a 3- or 4-wire system can be connected as a 4 to 20 mA signal directly or using temperature transmitters (e.g. TMT181). A separate transmitter power supply is installed for each analog or pulse input. The available outputs are signal types 0/4 to 20 mA, pulse, digital and relay. The number of inputs, outputs, relays and transmitter power supplies contained in the basic device can be individually extended over a maximum of three plug-in cards.

In applications with overheated steam, the process is monitored for saturated steam or wet steam. If the saturated steam curve is reached, this can be output as an alarm value. The summation of the calculated values is not interrupted when process limits (e.g. saturated steam curve) are exceeded or below set values. The most recently valid values are registered in the event memory when they leave or return to the valid process limits.
