KEITHLEY 7402 Thermocouple Scanner Card


General description of the used KEITHLEY 7402 for sale.
The Keithley 7402 Nine Channel Thermocouple Scanner Card permits monitoring of up to nine thermocouples or other transducers. The nine signal channels use a guarded 2-pole configuration. An isothermal block provides electrical isolation up to 42 V while assuring excellent thermal conductivity between cold junction terminations. A sensing device mounted in the isothermal block monitors the cold junction and outputs a calibrated reference voltage that is linearly related to the temperature. Specifications. Number of Channels: 9. Card Configuration: Multiplexer. Contact Configuration: 2 form A. Maximum Voltage: 110 V. Maximum Current: 1 A. Maximum Power: 60 VA. Contact Potential: <1 uV. Contact Life: >10^8 closures cold switching; >10^6 closures at maximum signal levels. Connection Type: Screw terminal. Temperature Offset: ±0.05° C maximum from HI to LO of any channel or between any two adjacent channels in one column on the isothermal block. ±0.1° C maximum between any two terminals on the isothermal block. Maximum additional dynamic offset due to 10°C step change in environment: ±0.1°C after one hour settling. Reference Output: +200 uV/C (+54.63 mV at 0°C).
