The VX4330 120-Channel Relay Multiplexer Module is a printed circuit board assembly for use in a mainframe conforming to the VXIbus Specification. The VX4330 provides six 1 10 4-wire multiplexer (mux) sections. Each of these six sections can be independently configured under software control as two 1 10 2-wire muxes, a 1 20 2-wire mux, or as a 1 40 1-wire mux. In addition, each section can be programmed to connect it to the section above or below it to produce up to a 1 60 4-wire mux, a 1 120 2-wire mux, or a 1 240 1-wire mux. The VX4330 provides the following features:
the highest density available in a single slot VXI relay mux module 120 2-wire channels
2 A maximum switching current per contact
220 VDC, 250 VAC maximum switching voltage per contact
60 W, 125 VA maximum switching power per contact
latching relays for low-power, low-noise operation
two 160-pin DIN front panel connectors
low-cost VXI local bus slave interface
Option 01 - this option enables the VX4330 to control up to 11 additional relay modules from the Tektronix family of relay modules. These modules are controlled via the VXI P2 local bus.
