This unit
The Agilent/Keysight E1347A is a 16-channel thermocouple low-offset relay multiplexer for precision temperature measurement in demanding test environments. This B-size, 1-slot VXI module features low-thermal offset reed relays with built-in thermistor reference junction compensation. It supports both 3-wire and 8-channel 4-wire configurations, scanning up to 600 channels/second when integrated with compatible Keysight DMMs such as the E1326B or E1411B.
Technical Specifications
- Module Type: General-purpose reed relay multiplexer
- VXI Form Factor: B-size, 1-slot
- Channel Count: 16 channels
- Configurations: 16-channel 3-wire or 8-channel 4-wire multiplexing
- Relay Type: Reed relays with break-before-make action
- Thermal Offset: <4 µV (differential, Hi-Lo)
- Relay Life: 10^8 operations minimum (no load); 10^7 operations minimum (rated load)
- Relay Behavior: Open on power down; open on power up
- Reference Junction Accuracy: 0.3 °C (18–28 °C operating range)
- Scanning Rate: 600 channels/second typical
- Maximum Voltage: 120 Vdc / 120 Vrms (any terminal to any other terminal or chassis)
- Maximum Current: 50 mA per channel common (non-inductive)
- Maximum Power: 1 VA per channel
- Closed Channel Resistance: 100 Ω ± 10%
- Screw Terminal Wire Gauge: 16–26 AWG (0.5–1.5 mm diameter)
Key Features
- Integrated thermistor reference junction for cold junction compensation
- Low-thermal offset design (<4 µV) minimizes measurement error in precision thermocouple applications
- Switches high, low, and guard on all 16 channels for flexible circuit topologies
- Compatible with Keysight E1326B and E1411B DMMs for automated temperature and voltage/current measurement
- Two- and four-wire resistance measurement capable when paired with compatible VXI instrumentation
Typical Applications
- Automated thermocouple data acquisition and temperature monitoring
- Multi-channel precision voltage and current measurement
- Resistance measurement (2-wire and 4-wire configurations)
- High-reliability switching in laboratory and production test environments
Compatibility & Integration The E1347A integrates into B-size VXI mainframes (e.g., Agilent E1300B or E1301B) via analog bus cable. C-size mainframe operation requires the E1403C active adapter. One analog bus cable is supplied for connecting adjacent slot modules. The module shares its component card (E1345-66201) with E1343A, E1345A, E1346A, E1355A, and E1356A models, with differences in terminal block configuration only.

Agilent / Keysight E1347A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E1347A. Calibration covers all module-specific parameters per manufacturer datasheet, output accuracy and linearity, frequency accuracy, and VXI register and trigger bus compliance. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight E1347A faults: relay contact wear, DAC/ADC drift, VXI backplane connector oxidation. Common faults include relay contact wear, DAC or ADC gain drift, and VXI backplane edge connector oxidation. Most modules are repaired at the component level with full post-repair verification in a C-size or D-size mainframe.
