The PXI‑2521 is a general-purpose switch module that features independent double‑pole single‑throw (DPST) armature relays. Each relay is nonlatching with very low on-resistance and low thermal offsets. The PXI‑2521 is fully software programmable, and it supports onboard relay count tracking. With an efficient coupling of voltage/current capability and relay density, this switch module is ideal for automated test equipment (ATE) loads or for controlling heaters, lights, and fans.
You can request repair, schedule calibration, or get technical support. A valid service agreement may be required.
