Overview
The 40-161A-903-HI (PXI) and 42-161A-903-HI (PXIe) are power relay modules with 12xSPDT relays which can be controlled by software as 6xDPDT. They are suitable for switching loads up to 16 A at 250 VAC and include an optional hardware interlock.
Power relay modules are intended for switching heavy AC or DC loads or for controlling large external relays, contactors and solenoids. The 40/42-161A range is ideal for switching up to 16 A in both AC and DC applications.
Power Relay Type
The 40/42-161A range is fitted with electromechanical power relays with silver alloy contacts. A spare relay is included with each module to allow easy maintenance with minimum downtime.
