The Model 7037 consists of a multi-pin (mass termination) connector card and a relay card. External test circuit connections are made via the 96-pin male DIN connector on the connector card. Keithley offers a variety of optional accessories that can be used to make connections to the connector card. The Model 7037 has 30 independent channels of single-pole switching. It also has ten independent inputs and outputs for digital I/O capabilities. Some of the key features include: • Low contact potential and offset current for minimal effects on low-level signals. • High density switching and control. • High capacity digital output sink of 250mA. • 1A pathway current carrying capacity. • High isolation resistance >1G W for minimal load effects. • Model 7011-KIT-R connector kit that includes a 96-pin female DIN connector that will mate directly to the connector on the Model 7037 or to a standard 96-pin male DIN bulkhead connector (see Model 7011-MTR). This connector uses solder cups for connections to external circuitry and includes an adapter for a round cable and the housing.
