Information

The Model 7059 is a low voltage scanner Plug-In card which is field-installable in the model 705 and model 706 scanner mainframes. The Model 7059 will switch up to 10 channels. For low-level transducer and thermocouple output switching the Model 7059 is designed to introduce a minimum of thermal voltage error ( < 1µV input to output with copper leads), and ensure that high isolation (10¹²Ω) is maintained between input signals. Expected relay life (10⁶ closures) is obtained when signals less than 10V or 10mA are switched. However, peak signals up to 200V or 100mA may be switched with the scanner, Quick disconnect screw terminals are used to facilitate input and output connections to the scanner Plug-In card (relay cardl. The Plug-In card is easily removed through the rear panel of the scanner mainframe.
