The RM-2000-RTDW motor-monitoring device can be used to monitor and/or control
SymCom's Model 777 via an RS-485 Modbus network. Two form C output relays are
available for an RTD alarm and a warning alarm. Alarm and trip levels can be set for each
RTD to activate the RTD alarm and deactivate the 777 output relay respectively.
In addition, the RM-2000-RTDW has two inputs: one to connect to a ground-fault module
and the other for connection to a remote reset button.
A second communication port allows monitoring and control of up to 99 RM-2000-RTDW
devices from a computer with SymCom's Solutions software, or a PLC, DCS, or SCADA
system. The RM-2000-RTDW is environmentally protected and can easily be mounted on
the front of a panel or MCC.
The RM-2000-RTDW displays the following
motor information:
• Real-time line currents, average current
and current unbalance
• Current to ground
• Line-to-line voltages, average voltage
and voltage unbalance
• Instantaneous power
• Power factor
• Last four faults
• All programmed 777 settings
• Remaining restart delay times
• 8 RTD temperatures
• Warning settings
The RM-2000-RTDW is also equipped with a
real-time clock, which allows access to the
following motor management information:
• Total motor run-time (reset capable)
• Time and date of last four faults, with voltage and current at time of trip
• Time and date of last ten motor starts
• Total number of motor restarts (reset capable)
• Minimum time between any two starts with time and date
• Run-time since last start (reset capable)
• KWhs consumed
• KVARs consumed
