Control and monitoring modules ConTrace MS1 and MS3 are full-fledged single-channel controllers capable of operating with maximum efficiency as a part of the multichannel specialized control system ConTrace. The control module is designed to control a three-phase or single-phase load using one of the options: an electromagnetic contactor, a solid-state relay or a continuously adjustable device controlled by a voltage of 0...10 V.
Control and monitoring modules ConTrace MS have a two-color OLED-display and navigation buttons. Thanks to the intuitive interface and a sufficient number of indicators and controls on the device itself, each module can be configured from the front panel. The ConTrace MS module can also be configured by connecting a PC or laptop to the USB Type C connector on the front panel of the module. Remote configuration and management of the device is performed via the RS-485 interface.
The control module continuously measures the operation current, as well as the leakage current in a non-contact manner. In the event that the leakage current exceeds the value set by the operator or the load current exceeds the specified range, an alarm message is output and the load is disconnected. In this case, for the leakage current, a warning value can be set, after which the device will signal an event, but the heating will not be stopped.
Modules ConTrace MS are able to notify the expiration of the resource of individual nodes of the system, according to such parameters as the number of cycles of on-off contactor and the time of operating the heating cable. These values are available for user customization. In addition, the user is provided with information on the total running time of system and operating time of the ConTrace MS module after the last reboot.
The MS module has four digital inputs to monitor the operation of the actuators and receive remote control commands. The module also has a configurable discrete output, triggered by a user-defined scenario.
The function of emergency redundancy of MS modules is realized by the 1+1 principle, i.e. the same MS module is connected to the main MS module via a special connector. The backup module monitors the operation of the main control module and in the event of a failure of the main control module, the standby module intercepts control by itself. Also, a temperature sensor can be connected to the backup module, in which case it will act as a temperature limiter. This significantly increases the reliability of the control system and is applicable for particularly important loads.
