PC-73C 8 Channel Thermocouple/RTD 8 differential input channels for thermocouple or RTD sensors Use with K,J,E,T,B,R,S & N thermocouples + 100 Ohm or 1k Ohm RTDs Cold Junction compensation and screw term. block on auxilliary board Gains selectable from: 1, 10, 100, 200, 300, 500, 600, 700, 800 30 to 50Hz acquisition rate via polled I/O and Interrupts.The PC-73C-T and the PC-73C-R are thermocouple and RTD measurement boards giving very stable and accurate measurements. They are ideal for precision laboratory and industrial applications. Exceedingly low noise levels of ±1 count (or 0.5șC or less for J type thermocouples without averaging) have been achieved and performance standards are in excess of even stand-alone amplifiers. It is possible to connect a mixture of thermocouple types on the PC73C-T and 2/3/4 wire RTDs on the PC73C-R. Hardware consists of a PC plug-in board and an Auxilliary board which contains Cold Junction compensation and terminals. Wait-state generation has been incorporated on the PC 73C which allows operation in very fast computer. The Digital Input / Output lines is an added feature on the PC73C boards and is connected to the PC backplane via an auxilliary DB25 male connector. The digital inputs can be used as trigger lines to sample data or determine the states of switches, etc. The digital outputs have a 24mA driving capability and can thus be used to switch on a buzzer or alarm. |
