VSM+

The PLC+ product line was developed by Altronic to allow easy integration of engine/compressor/generator function specific I/O through Ethernet to industry standard PLCs. The PLC+ Modules are designed to seamlessly deliver efficient, hazardous area approved, cost effective I/O functions that are not normally available by off-the-shelf PLC hardware. The PLC+ modules were designed with Rockwell Automation Control Logix and Compact Logix in mind. EtherNet/IP, implemented in the PLC+ Monitors, along with ModbusTCP allow seamless communication over Ethernet to Rockwell Automation PLCs as well as a wide range of other industrial PLCs. The PLC+ Monitors are based upon taking a time tested Altronic designed and tested specialty I/O function such as Analog and digital I/O, vibration, detonation, speed, and others and marrying it to a communications board packaged in a rugged cost effective shock and dust-resistant package. The VSM+ Vibration Sensing Monitor is a module in the PLC+ product line. It uses the patented vibration monitoring technique of the VSM-800 and adds an integrated Ethernet port. It is designed to protect industrial engines, compressors, and associated equipment from damage caused by excessive vibration. It accepts up to 8 industry-standard, low-cost, broadband, piezoelectric vibration sensors that are used to transform mechanical vibrations into electrical signals which are then evaluated by the VSM+. Each input channel operates independently of the other. It is designed for use as a component of a PLC+ Control Panel, or as a stand-alone product. PLC+ panels use one or more such devices for engine control and monitoring. The Ethernet port allows the monitored values to be communicated to a PC, PLC, or other communications device using either Modbus/TCP or EtherNet/IP protocol. These values can be displayed on an HMI display and compared to user adjustable setpoint levels for alarm and shutdown.
