IS speed monitor features both analog and relay outputs
July 2002Maintenance, Test & Measurement, Calibration
Turck is now offering the new multimodul MK21-RI - claimed to be the industry's first rotational speed monitor featuring intrinsically safe inputs with both relay and analog outputs. Designed to monitor pulse sequences from NAMUR sensors in hazardous locations, convert the NAMUR sensor pulse input into a 4 to 20 mA rotational speed output and indicate overspeed and underspeed conditions to control equipment in nonhazardous locations, the multimodul MK21-RI replaces two control devices. Using fewer control components simplifies the system while minimising cost and required panel space.
The multimodul MK21-RI's analog speed output is a 4 to 20 mA signal proportional to the rotational speed. This device can detect rotational speed from 1 MHz to 10 kHz (0,06 to 600 000 RAM). An LCD display indicates actual speed, measured in user-defined units.
The MK21-RI's relay output monitors speed independently and energises the overspeed/underspeed relay when rotational speed goes above the overspeed setpoint or below the underspeed setpoint. Switch 'on' and switch 'off' setpoints can be set for the underspeed and overspeed values, allowing the user to establish a predetermined hysteresis for overspeed and underspeed setpoints.
Set-up, programming and monitoring operations are quick and easy. Menu-driven software provides programming prompts on the LCD screen and users input the requested information using two buttons below the screen.
The MK21-RI can be programmed to monitor the input circuit for wire-break and/or short circuit. With input circuit monitoring activated, if a corresponding fault in the input circuit occurs, the output relay de-energises and the switching status LED illuminates.
The MK21-RI keeps users apprised of operating status with a red LED that indicates switching status, a green LED that indicates 'power on' and a yellow LED that indicates whether or not the overspeed/underspeed relay is energised.
