SCXI-1308

National Instruments SCXI-1308 32-Channel Current Input Terminal Block
Features

• 249 Ohm Precision Resistor Across Each Input
• Mounts to Front of SCXI Module
• Shielded for Quick, Convenient Signal Connections

The National Instruments SCXI-1308 32-channel current input terminal block is a shielded board with screw terminals that connects to the SCXI-1102/B/C and the SCXI-1100 modules. The SCXI-1308 has thirty-two 249 Ω precision resistors to convert current to voltage when measuring 0–20 mA and 4–20 mA process current sources.

The terminal block has 78 screw terminals for easy connection. Thirty-two pairs of screw terminals connect to the 32 differential inputs of the SCXI modules. One pair of terminals connects to the module’s chassis ground pins. Three terminals connect to the SCXI module OUPUT and AOREF pins and to the SCXIbus guard. All of the other terminals—OUT0+, OUT0–, OUT1+, OUT1–, OUT2+, OUT2–, OUT3+, OUT3–, and AIREF—are reserved for future use.
