Compatible with both E Series and 1200 Series data acquisition boards, the SC-2075 operates with a 15 V power supply that can be selected from the board or provided externally. Its removable breadboard enhances convenience for users. The accessory features multiple output positions, including three for 15 V outputs and two for 0-5 V outputs, along with two positions dedicated to measuring analog signals or DC voltage. Connectivity options include two BNC connectors for analog inputs, two for analog outputs, and one for trigger signals. The SC-2075 is equipped with a total of 35 spring terminals for analog inputs and control signals, seven additional terminals for counter control, and two terminals for TTL-level power or ground signals. Furthermore, it supports digital I/O signals through eight dedicated terminals linked to DIO signals. To set up the SC-2075, a 68-pin E Series device connected via a 68-pin cable or a 50-pin 1200 Series device with a 50-pin ribbon cable is required. The accessory has been designated as obsolete by National Instruments; however, it remains available for purchase and repair through Apex Waves.
