3720

3720 is a multiplexer card that offers two independent banks of 1 x 30 two-pole multiplexers. It is ideal for general purpose switching, including temperature measurements. The two banks can automatically be connected to the series 3700A mainframe backplane and optional DMM through the analogue backplane connection relays. This connection allows the mainframe to reconfigure the card to a single 1 x 60 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. Other features of the device include its ability to be reconfigured to coordinated four-pole operation for additional measurement flexibility. Furthermore, the device supports thermocouple type temperature measurements when used with the Model 3720-ST (screw terminal) accessory providing automatic cold junction compensation (CJC). It uses two 78-pin male D-sub connectors for signal connections.

• Screw terminal connections provided with removable 3720-ST accessory
• Relay closures stored in on-board memory
• Latching electromechanical relays
• 300V, 1A switched or 2A carry signal capacity (60W, 125VA)
