Pickering 40-156-001 Power Relay Module

The Pickering 40-156-001 is a 16-channel PXI power relay module engineered for high-power switching in automated test systems, instrumentation, and industrial control applications. Each channel comprises a Single Pole Double Throw (SPDT) relay with gold flash over silver alloy contacts, delivering 5 ms typical switching speed and proven reliability across millions of cycles. The module handles hot switching to 5A at 35VDC or 250VAC, and cold switching to 5A at 400VDC or 250VAC peak, with maximum power dissipation of 175W or 1250VA. An integrated spare relay minimizes downtime during field maintenance.
