Specications
The RM-2000
is a motor-monitoring device to be used in con-
junction with SymCom’s Model 777 family of
products (excluding the P1 Series), 77C family of
products and the Model 601 voltage monitors, via
Modbus protocol with a communications module.
The RM-2000/777 motor management system com-
bines unsurpassed electronic motor protection and
critical, user-friendly, motor monitoring.
The RM-2000 has membrane keypad controls
which allow both monitoring and control of a 777
MotorSaver
®*
through an RS-485 network using
Modbus RTU protocol. A second communication
port allows monitoring and control of up to 99
RM-2000 devices from a PLC, DCS, or SCADA
system or a PC with Solutions software installed.
The RM-2000 will act as a repeater for its motor
protector when accessed from the host computer or PLC. In addition to the monitoring functions,
the RM-2000 can be used to reset a tripped MotorSaver
®
or PumpSaver
®
.
The RM-2000 is easily mounted remotely and improves safety for service and operations personnel
by allowing them to control and monitor the device without opening the electrical cabinet. Using the
RM-2000 is a simple, cost-effective method for aiding compliance with arc flash safety regulations.
The enclosure and keypad assembly is water and ultraviolet light resistant.
