Functional Description
The transmitter converts a vibration-related transducer signal into a standard analog current signal for use by a control or monitoring system. A 4-20 mA signal, if confirmed for this configuration, allows a PLC or DCS analog input to receive a scaled measurement for display, trending, and alarm processing.
The supplied specifications also list Modbus RTU and EtherNet/IP. These interfaces are not independently confirmed for the exact part number, so verify the communication options and terminal assignments before selecting the receiving system.
Configuration and Selection
Confirm the complete part number, 1800/15-12-90-02-00, against the installed unit’s nameplate and applicable documentation. Before replacing an existing transmitter, check the required transducer type, cable configuration, measurement variable, output scaling, supply requirements, and control-system input compatibility. Do not assume that units in the same product family share identical electrical or measurement characteristics.
Frequently Asked Questions
Q: What is the function of the 1800/15-12-90-02-00?
A: The supplied product description identifies it as a relative vibration transmitter for machinery monitoring. Confirm its input requirements and measurement configuration before connecting it to an existing monitoring loop.
Q: Can the transmitter connect directly to a PLC or DCS?
A: The supplied data lists a 4-20 mA analog output. Direct connection depends on the verified output configuration, receiver input type, loop power arrangement, and signal scaling.
Q: Does this model support Modbus RTU and EtherNet/IP?
A: The supplied information lists both protocols, but model-specific confirmation is unavailable. Verify the communication interfaces against the exact hardware and its technical documentation before designing a network connection.
