Agilent / Keysight E1465A 16 x 16 Relay Matrix Switch

The Agilent/Keysight E1465A is a C-size VXI relay matrix switch module delivering 256 crosspoints in a compact 16×16 two-wire configuration. Engineered for automated test, signal routing, and data acquisition, this register-based module handles voltages to 200 Vdc or 170 Vacrms, with per-channel current ratings of 1 A and maximum power dissipation of 30 W per channel. The latching armature relay design ensures low on-resistance - less than 4.0 Ω worst-case and under 1.8 Ω best-case at initial contact, degrading to under 10.0 Ω end-of-life.

Insulation resistance exceeds 10⁸ Ω under humid conditions and 10⁹ Ω at standard lab conditions.
