General Information
2-channel MK40 Control Module is designed for measuring of tachometric signals. MK40 is based on high-
performance microcontroller, use of which permits to process signals from sensors in real-time mode (measurement
periods up to 0.1s) and support, in parallel, digital control interfaces.
Measuring channels operate synchronously but independently of one another. Measuring channels basic
functions are:
•
Measurement of sensors DC current and monitoring of sensors and communication line functionality;
•
Measurement period of rotor speed from 0.1 to 1.0 second (equal for both measuring channels);
•
Adjustable number of gear teeth (pulse count per rotor revolution);
•
Selection of sensor signal active front (determined by bridge on the module board);
•
Repetition of basic tachometric pulses for synchronization of control modules, calculating rotational
components and phases (for example, MK20 and M30 modules);
•
Rotor stop block detection and rotor stop block alarm testability (“STOP” mode);
•
Calculated frequency value comparison with set-points (3 set-points for each channel);
•
Calculation of maximum rotor speed;
•
Calculated parameter value transfer to standard current output.
Other MK40 Module features include:
•
Measuring channels input signals: 0(1) – 5mA; 0(4) – 20mA; 0 – 5V.
•
Six logic outputs with adaptable algorithm for alarm and protection circuits implementation;
•
Two standard current outputs with programmed range setup option;
•
Supported communication interfaces: RS485, CAN2.0B, diagnostic interface;
•
Utility software for PC rendering of the module actual state, setting and calibration;
•
Module in several design options:
•
MK40-DC – 20mm 3U narrow front panel, restricted module state alarm system, +24V DC
voltage power supply;
•
MK40-DC-11 – 40mm 3U front panel, bright 7-segment digital display with extended module
indication and control system, +24V DC voltage power supply;
•
MK40-DC-001 - 40mm 3U front panel, a customized alphanumeric LCD with measurement
results displaying capability in all measuring channels simultaneously, +24V DC voltage power
supply;
•
MK40-AC-11-S – 40mm 3U front panel, bright 7-segment digital display with extended module
indication and control system, AC 220V 50Hz power supply and power-on toggle-switch,
installed on the front panel.
•
Transducers (sensors) +24V DC voltage power supply is provided through self-healing 200mA fuse,
installed on MK40 Module board.
•
50Hz test signal generation for MK40-AC-11-S design option.
Overall MK40 Module setting up is implemented by PC or dedicated ПН31 setting unit. In order to setup the
module by means of PC, MK40_setup.exe software should by run on PC and MK40 Module should be connected to
PC via MC01 diagnostic interface board (RS232 PC Interface) or MC01 USB (USB PC interface).
