Keysight/Agilent E1347A 16-Channel T/C Low-Offset Relay Multiplexer
The E1347A 16-Channel T/C Low Offset Relay Multiplexer device supports thermocouple switching within VXI measurement domains. It operates through one B-size register VXI slot configuration. The module provides 16- and 3-wire multiplexed channels supporting accurate thermal acquisition across industrial instrumentation platforms. The configuration also supports 8- and 4-wire channels for resistance temperature measurement.
The thermistor reference junction improves temperature stability during scanning operations using compatible digital multimeters. The E1347A Relay Multiplexer integrates low-thermal reed relays, producing offsets below 4 millivolts. The channel scanning functionality updates thermal measurements across automated validation systems requiring synchronized acquisition performance. It measures temperature, voltage, and current parameters through multiplexed routing architecture supporting laboratory instrumentation requirements.
The input terminals tolerate maximum current voltages reaching 120 volts between isolated chassis connections. Each channel supports maximum current levels reaching 50 milliamperes during switching applications without degradation. The maximum channel power handling reaches 1 volt-ampere, supporting connections within specified operational tolerances. The register-based VXI architecture operates through A16 slave communication protocols without shared memory implementation capabilities.
The unit uses one P1 connector supporting hardware integration requirements. The module excludes bus resources, ensuring compatibility across legacy register-based instrumentation control platforms. The compact B-size construction occupies one installation slot supporting chassis utilization throughout automated testing environments. The maximum thermal offset remains below 4 mV between high and low measurement terminals during operation.
Closed channel resistance reaches 100 ohms with ±10% tolerance, supporting stable signal transmission characteristics. Insulation resistance between isolated points reaches 10? Ohms supporting reliable electrical isolation during measurements. The power-off high-to-low insulation specifications remain unavailable as the protection design excludes this configuration. The module's current consumption requires 0.2 A from the +5 V supply during active operating sequences. The +12 V supply requirement reaches 0.13 A, supporting relay switching across multiplexed channel configurations.
The AC bandwidth reaches 10 MHz using 50 ohm source and load configurations during operation. The channel crosstalk performance reaches -80 dB at 100 kHz during continuous scanning operations. The high-frequency performance reaches -40 dB at 10 MHz across adjacent channel configurations. The E1347A T/C low-offset multiplexer supports high-low capacitance values below 150 pF.
The command module firmware revision A.06 supports communication stability across integrated measurement control architectures. I-SCPI Win 3.1 compatibility enables direct software integration within standardized automation environments.
