The National Instruments ER-16 Electromechanical Relay is a versatile device designed for various control and switching applications. Featuring 16 isolated SPDT (Form C) relay channels, the ER-16 can be expanded to a maximum of 32 channels through daisy chaining. Each channel supports an isolation voltage of up to 250 Vrms, and the relay's operating mode is configured as break-before-make. The ER-16 is compatible with a vast range of NI digital data acquisition (DAQ) boards and can interface with MIO and Lab devices using the SC-205X cable adapter. It boasts easy installation with screw terminals for field connections and can operate on a nominal coil voltage ranging from 5 to 48 VDC. The device has a nominal power consumption of 360 mW for the standard type and 250 mW for the high-sensitive type, with an operate power of 177 mW and 130 mW, respectively. The ER-16 features an operate time of 10 ms and a release time of 5 ms, ensuring efficient responsiveness. Enhanced safety is prioritized with built-in arc-suppressor pads, particularly beneficial in inductive load scenarios. The device is rated for an operating temperature range of –40 to 85 °C for the standard type and –40 to 90 °C for the high-sensitive type. With compact dimensions of 6.9 x 2.05 x 4.82 inches and a mass of 8 grams, the ER-16 is ideal for environments requiring robust testing, monitoring, and control capabilities. For power, the relay can draw directly from connected DAQ devices, but it also accommodates an external power supply if needed, with built-in connections provided. The ER-16 comes with a three-year warranty, and user documentation is available for download. For pricing information, please contact a sales representative.
