3724

3724 is a FET multiplexer card that provides two independent banks of solid-state relays arranged as 1 x 30 two-pole multiplexers that are ideal for high reliability, high speed multipoint measurement applications including temperature. 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. The solid-state FET relay technology supports fast switching times with scanning rates of greater than 1250 channels/second and provides unlimited contact life. In addition, the device supports thermocouple temperature measurements when used with the Model 3724-ST (screw terminal) accessory providing automatic cold junction compensation (CJC). The device uses two 78-pin male D-sub connectors for signal connections.

• Analogue backplane connection relays provide easy bank and card interconnections
• Ideal for maintenance-free, long-life thermocouple temperature measurements
• 200V, 0.1A Switch/carry signal capacity - 800mW
