Keysight / Agilent / HP E1469A 4 x 16 Relay Matrix Switch

The Keysight/Agilent/HP E1469A is a 4×16 relay matrix switch module designed for signal routing in automated test equipment and general-purpose switching applications. This C-size, 1-slot VXI module employs latching relays to deliver two-wire switching with both high and low control on each of its 64 crosspoints, plus guard/shield capability. The module supports expansion through daisy-chain interconnection to build larger matrices. ## Technical Specifications Matrix Configuration • 4 rows × 16 columns • 64 total crosspoints • Two-wire switching with dual control (high and low) per crosspoint • Guard/shield capability included Relay Architecture • Latching relay design • Closed channel resistance: <1.5 Ω initial, <3.5 Ω end of life • Maximum thermal offset (differential Hi-Lo): 7 µV per channel Voltage and Current Ratings • Maximum voltage (any terminal to any other or chassis): 220 V DC or 250 V AC RMS • Maximum current per channel (non-inductive): 1 A DC/AC RMS at <30 Vdc/rms; 0.3 A DC/AC RMS at <220 Vdc/rms • Maximum power: 40 VA DC per module Physical and Interface • VXI Module: C-size, 1-slot • QUIC easy-to-use terminal block • Expansion connectors for module interconnection ## Key Features • Latching relay architecture eliminates continuous hold power • Low contact resistance maintains signal integrity across switching cycles • Dual high/low switching per crosspoint enables flexible signal control • Guard capability reduces crosstalk in sensitive measurements • Modular design supports expansion via daisy-chain cabling ## Typical Applications Signal routing in production test systems, burn-in test environments, and general-purpose switching for multi-channel test configurations requiring moderate voltage and current handling. ## Compatibility & Integration Multiple E1469A modules interconnect using the Model E1468-80002 daisy-chain cable. Three modules create a 4×48 matrix; four E1468A modules with interconnection cables form a 16×16 matrix. The E1469A shares the same component card as the E1460A. For applications exceeding 64 crosspoints where high voltage/power capability is not required, the E1465/66/67A relay matrices offer alternative configurations.
