60 two-pole or 30 four-pole solid-state channels
Scanning speeds greater than 1250 channels/second (switch only)
Optically isolated, solid-state FET relays provide unlimited contact life
200V, 0.1A switch/carry signal capacity; 800mW
Automatic CJC for temperature measurements when used with 3724-ST accessory
Analog backplane connection relays provide easy bank and card interconnections w/ terminal connections provided with removable 3724-ST accessory
Ideal for maintenance-free, long-life thermocouple temperature measurements |
|
The Model 3724 provides two independent banks of solid-state relays arranged as 1x30 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 3700 mainframe backplane and optional DMM 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. 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 Model 3724 supports thermocouple temperature measurements when used with the Model 3724-ST (screw terminal) accessory providing automatic cold junction compensation (CJC). The Model 3724 uses two 78-pin male D-sub connectors for signal connections. For screw terminal or automatic CJC, use the detachable Model 3724-ST accessory. |
