SPEED+

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 Modbus/TCP, 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 device with specialty I/O functions 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 Speed+ Speed Monitor is a module in the PLC+ product line. It converts engine and rotating equipment speed to Ethernet/IP or Modbus TCP for use in PLC’s to monitor and control processes. The speed input pulse can come from magnetic, Hall-effect, or other types of active pickups or from C.D. Ignition Systems. The speed output can be at selected ratios to the measured RPM. Speed range is up to 65,000 RPM. A configurable 4-20mA analog output signal with respect to speed is offered for direct process control or directly to an Altronic Ignition System for timing control. The Speed+ has three adjustable setpoints that can be individually mapped to either or both of the two output switches. The Speed+ 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 sequencing, and/or alarm and shutdown.
