Dual 4x28 2-pole configuration
The dual 4x28 2-pole configuration allows you to automatically link four contact sets to act as two
pairs. Using the internal relays, you can create a matrix consisting of two banks of paired crosspoints,
each with four rows and up to 28 columns. Using the Model 3732-ST-C screw terminal assembly is
optional in this configuration.
