data sheet 256-channel reed relay multiplexer agilent E8460A ? 1-slot, c-size, register based ? high-density, low-cost multiplexer ? fast scanning rate ? flexible reconfiguration ? contact protection for reliable operation ? three different easy-to-use terminal blocks available as options agilent E8460A with opt. 014 description the agilent technologies E8460A high-density reed relay multiplexer is a c-size, 1-slot, register-based vxi module . this 256 - channel multiplexer, using reed relay switches, offers a fast, reconfigurable, high point-count switching topology. it is designed for applications requiring fast scanning rates by the use of fast action reed relays. this single-slot multiplexer extends the choices of multiplexers available to the system engineer. the E8460A can be programmed into individual topologies; some common examples are shown in the table below. many other combinations of these topologies are supported (in addition to those shown in the table). two-wire, three- wire, and four-wire measurements can be configured. refer to the agilent technologies website for instrument driver availability and downloading instructions, as well as for recent product updates, if applicable. common multiplexer configurations one 256 x 1 four 64 x 1 one 128 x 2 two 32 x 4 one 64 x 3 sixteen 16 x 1 ?? ?? ??
2 accessories a terminal block does not come with the module. three different terminal blocks are available as options: one for crimp-and-insert connectors, one for ribbon cable connectors, and the other for fault-tolerant protection of dut inputs, where each channel has a positive temperature coefficient resistor that behaves like a resettable fuse and will increase impedance when excessive current is flowing in a channel. one 2.5-in. analog bus cable (e1400-61605) is included to connect the analog busses of multiple slot-adjacent E8460A modules or a slot-adjacent e1411b multimeter module. the analog bus cable, easily installed at the faceplate of the component card, lets you connect the E8460A with the e1411b dmm. product specifications input note: these limits apply only if no connection is made to power mains. maximum input with opt. 012 terminal card with opt. 014 or opt. 015 terminal card analog bus maximum dc voltage: 200 v 60 v 60 v max. acrms voltage: 140 v 50 v* 30 v max. acpeak voltage: 200 v 70.7 v 42 v max. current per channel: switching: 300 ma 100 ma n/a carry: 500 ma 100 ma n/a maximum power per channel: 5 va maximum power (resistive load): per channel: 5 va per common output: 5 va per module: 60 va *rating reduced to 30 vac-rms, 42 vac-peak for exposed conductors. dc performance typical thermal offset (per channel): 50 v closed channel resistance: < 3 with output protection resistor shorted, protection resistor adds 100 ac performance bandwidth, 50 source/load configuration 100 protection resistor shorted 256 x 1: 4.5 mhz 64 x 1: 12.0 mhz 16 x 1: 30.0 mhz closed channel capacitance configuration to chassis to open channel 256 x 1: 1400 pf 70 pf 64 x 1: 460 pf 70 pf 16 x 1: 140 pf 70 pf open channel to either open channel or to chassis capacitance: 70 pf hi-to-low capacitance (2-wire mode) configuration capacitance 256 x 1: 400 pf 64 x 1: 230 pf 16 x 1: 80 pf crosstalk configuration 10 khz 100 khz 1 mhz 10 mhz 256 x 1 (channel to chassis): C84 db C64 db C44 db C30 db 64 x 1: C84 db C64 db C44 db C27 db 16 x 1: C83 db C64 db C44 db C24 db
