產品總覽
The 3740 is a 32-channel Isolated Switch Card offers 28 general-purpose form-C channels that is ideal for routing power or other control devices. For higher power applications of up to 7A, four additional high current form-A channels are provided. If any general purpose signal requires routing to the series 3700A mainframe backplane, terminal blocks are located on the card, which are enabled with jumpers. Custom configurations can be created with the user accessible terminal blocks. For additional protection, an on-board temperature sensor will notify the mainframe when the cards operating temperature exceeds 70°C, compromising system specifications. The device uses two 50-pin male D-sub connectors for signal connections.
