美国Keithley 3720-ST Screw Terminal Block 螺丝接线盒

吉时利3720 双1 x30多路卡提供了两个独立的记忆库，1 x30两极多路复用器。吉时利3720是理想的通用转换器,包括温度测量。这两个记忆库可以自动被连接到系列3700A主机背板和可选的数字万用表，通过模拟底板和连接继电器。此连接允许主机重新配置卡一个1 x60两极多路复用器或启用卡片卡片转换器扩张更大的配置。吉时利3720的其他特性包括重新配置的能力协调四端操作额外测量的灵活性。此外,吉时利3720支持热电偶温度测量时使用的吉时利第3720(螺丝接线端)附件提供自动冷端补偿(CJC)。吉时利3720使用了两个78插针，公sub连接器为中共信号连接。螺丝接线端或自动CJC,使用可拆卸的吉时利3720附件。

The Keithley 3720 Dual 1X30 Multiplex Card offers two independent banks of 1x30 two-pole multiplexers. The Keithley 3720 is ideal for general purpose switching, including temperature measurements. The two banks can automatically be connected to the Series 3700A mainframe backplane and optional digital Multimeter through the analog backplane connection relays. This connection allows the mainframe to reconfigure the card to a single 1x60 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. Other features of the Keithley 3720 include its ability to be reconfigured to coordinated four-pole operation for additional measurement flexibility. Furthermore, the Keithley 3720 supports thermocouple-type temperature measurements when used with the Keithley 3720-ST (screw terminal) accessory providing automatic cold junction compensation (CJC). The Keithley 3720 uses two 78-pin male D-sub connectors for signal connections. For screw terminal or automatic CJC, use the detachable Keithley 3720-ST accessory.
