Product Overview
The 3721 is a Multiplexer Card offers two independent banks of 1 x 20 two-pole multiplexers that are 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 device as a single 1 x 40 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. The device provides, in addition to the 40-channel, two fused channels are supplied for current measurements. Also, the device includes dedicated inputs that enable 40-channel of four-wire common side ohms measurements. For thermocouple type measurements, automatic cold junction compensation (CJC) is supported when used with the model 3721-ST (screw terminal) accessory. The device uses two 50-pin male D-sub connectors for signal connections.
