Description
The SC-2061 Digital Output Electromechanical Relay, with part numbers 776336-01 and 776336-11, is a product of National Instruments and is part of the SC-206x series. This device features 8 individually optically isolated digital output channels and is designed for compatibility with 8-bit digital ports of many NI DAQ devices through the use of SC-205x Series cable adapter devices.
Each channel offers an isolation of 250 Vrms, with a higher 400 Vrms isolation present between the channels and ground. The SC-2061 requires an external +5 VDC signal and a 4.7 kΩ pull-up resistor for each of its output channels to function correctly.
For installation, the relay provides flexible mounting options with metal standoffs for benchtop setup, and it is also compatible with rack-mount chassis. Despite its obsolete status announced by National Instruments, the SC-2061 remains available for purchase and repairs through Apex Waves.
