This is the fourth part in our series about the\u00a0National Instruments SCXI Series<\/strong><\/a>. This blog post will describe another type of SCXI switch module.<\/p>\n

 <\/p>\n

The second type of\u00a0National Instruments SCXI Switch<\/strong>\u00a0is general-purpose switch modules. These include the\u00a0SCXI-1161<\/strong><\/a>, which consists of eight independent SPDT (also called Form C) nonlatching relays. They can switch up to 8 A at 125 Vrms, 6 A at 250 Vrms, or 5 A at 30 VDC, making them suitable for higher power applications. Each channel has a normally closed (NC), normally open (NO), and common (COM) terminal. You can use two or more\u00a0NI SCXI-1161s<\/strong>\u00a0(and\u00a0SCXI-1160s<\/strong>) in the same chassis with a single DAQ device or switch controller. The DAQ device controls these SCXI modules through serial communication over the SCXIbus in the backplane of an SCXI chassis. The\u00a0NI 4021<\/strong>\u00a0switch controller or the\u00a0NI 40470\/4060<\/strong>\u00a0DMMs control these SCXI modules via the\u00a0SCXI-1362<\/strong>\u00a0cable assembly.<\/p>\n

Another general-purpose switching module is the\u00a0SCXI-1160<\/strong>. This module consists of 16 independent SPDT (also called Form C) latching relays with very low on-resistance and low thermal offset. With power capabilities of up to 2 A at 250 Vrms or 30 VDC, these relays are suitable for switching, routing, and controlling medium-level signals. Other features of the\u00a0NI SCXI-1160<\/strong>\u00a0are the same as the\u00a0NI SCXI-1161<\/strong>.<\/p>\n

There is also the\u00a0SCXI-1166<\/strong>\u00a0High-Current General-Purpose Relay Switch Module. The\u00a0NI SCXI-1166\u00a0<\/strong>has 32 channels and individual SPDT (Form C) nonlatching relays with low on-resistance and low thermal offset. This Relay Switch Module can switch up to 2 A at 30 VAC\/30 VDC and can carry 5 A per channel, making it perfect for switching, routing, and controlling high-current signals.<\/p>\n

Additionally, the\u00a0National Instruments SCXI-1167<\/strong><\/a>\u00a0is another type of SCXI Switch Module. This 64-channel external relay driver can provide up to 50 V or 600 mA of drive capacity when an external supply is utilized. The\u00a0NI SCXI-1167 Relay Driver Module<\/strong>\u00a0is the best solution when the current and voltage requirements for relays surpass those found in existing relay modules (or for relays embedded in a test system). The\u00a0NI SCXI-1167<\/strong>\u00a0includes overcurrent, overvoltage, and flyback protection to guarantee long-life operation. The\u00a0SCXI-1167<\/strong>\u00a0can drive small DC motors or other inductive relay coils as well.<\/p>\n

The last general-purpose\u00a0SCXI Switch Module<\/strong>\u00a0is the\u00a0NI SCXI-1169<\/strong><\/a>. This module has 100 channels and features SPST (Form A) armature relays. The\u00a0National Instruments SCXI-1169<\/strong>\u00a0is suited for medium-power automated test loads because it provides maximum relay density, with 100 latching relays in one SCXI slot. The\u00a0NI SCXI-1169<\/strong>\u00a0can switch up to 100 VDC\/100 VAC or up to 1 A. This SCXI module is completely software-programmable and contains a 32,000-step scan list for deterministic scanning capability.<\/p>\n
