The ConTrace IPS module, depending on the number of MS modules connected to it, is connected to the power units of the appropriate power, as well as to the RS-485 network, for communication with the industrial PC / PLC. Further, through the patch cord, it simultaneously transmits power and interface to the ConTrace MS modules. Further, through the patch cord, it simultaneously transmits power and interface to the ConTrace MS modules. IPS has 2 outputs, combining power and interface buses. For each output, up to 20 MS modules can be connected in series. Thus, with the help of one IPS, it is possible to power up to 40 MS modules.
ConTrace IPS can work from either one or two power supplies. Operation from two power sources is assumed by the principle of primary / backup, with automatic switching to a working power supply and simultaneous signaling by closing the alarm relay contact. The IPS module is protected against excess supply voltage.
Each of the two output power and interface lines is equipped with its own protection against overcurrent, undervoltage and overvoltage. The operation of the protection is indicated by the LEDs on the front panel. Resetting the protection is done by pressing the “Reset” buttons on the device, separately for each outgoing line.
ConTrace IPS is supplied with three terminators of the ConTrace BT bus. This set is sufficient for implementing any connection scheme.
