8-Channel Sensor Input Temperature Transmitter

8-Channel Sensor Input Temperature Transmitter: NCS-TT108 smart temperature transmitter adopt PVC fire-retardant plastic shell, which can be installed in the control room. When it is required to be installed outdoors.outdoor Aluminum box, with a water-proof body and die-cast aluminum materials, must be selected.

NCS-TT108 digital temperature transmitter uses digital technology. It has simple interface between field and control room, which reduces the expense of installation, operation and maintenance.

Mount of Transmitter

 Mount of guide rail                                                                                Mount of screw

When thetemperature transmitter needs mounting in outdoor, it must be mounted in outdoor box, whose case material is die-casting aluminum, and cable seal point is copper chroming.

                                           Outdoor case                                                                                    Mounted in outdoor box

Connection：

NCS-TT108 Temperature transmitter'spower and bus signal share one couple cable, called bus cable. Customer is advised to use dedicated cable especially for fieldbus, recommended by IEC61158-2. The bus connection terminal of this temperature transmitter is positioned at the very right of connection terminals. From left to right, they are ‘bus+’, ‘bus-’and ‘earth’, as showed in the following figure.

Of the left terminals of sensor's signal connection terminal strip, every three terminals in sequence form one channel’s connection terminal, and will connect channel one to channel eight sensors, from left to right in sequence. The detailed connection mode is showed as following figure.

                                                                                             Temperature transmitter connection

Signal cable and bus cable shall not share wiring tube or open wire trunking with other device and shall be far away from high-power device. 

                                                                                                 Cable sealing connector

There are nine cable sealing connectors for outdoor box. The connector on side wall, labeled ‘Power/Signal’, should connect fieldbus cable, and cable connectors on inferior wall should connect every channel sensor to connect cable, from left to right they are channel one, channel two…channel eight in sequence.
