4 Electrical installation
The IN 2000 is supplied with a direct current between 15 and 30 V. When connecting the device to the power
supply ensure correct polarity. The power consumption (in this case 4 - 20 mA) is also the measuring signal.
The IN 2000 is supplied via the USB port if connected via the USB adapter. A connection via PC is neces-
sary if pyrometer parameters must be changed.
The device does not need any time for starting or preheating and is immediately ready for operation. To
switch off the instrument, interrupt the power supply or unplug the electrical connector.
Wire colors:
white: +15 … 30 V (power supply)
brown: 0 V
black: screen
green: RxD (receive date of digital output)
yellow: TxD (transmit data of digital output)
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. The shield of
the connecting cable has to be connected only on the pyrometer’s side. On side of the power supply (switch
board) the shield must be open to avoid ground loops.
