KEITHLEY 3721 ບັດ Multiplexer ຄູ່ 1×20
Multiplexer Configuration:
Two independent 1×20 2-pole multiplexers
Banks can be connected together via relay creating a single 1×40 multiplexer
Banks can be isolated from the backplane by relays
Card can be configured for common side Ohms measurement via backplane relays.
Channel 41–42: Multiplex one of two 2-pole current signals into DMM.
Contact Configuration 2-pole form A.
Connector Type: Two 50-pin male D-shells. Removable screw terminal option.
Maximum Signal Level:
Channels 1–40: 300 V DC or RMS, 2 A switched (3 A carry), 60 Ω, 125 VA maximum.
Channels 41–42: 60 V DC or 30V rms, 3 A switched, 60 Ω, 125 VA maximum. Fused 3 A, 250 V rms.
Common Mode Voltage: Channels 1–40: 300V DC or rms between any terminal and chassis.
Volt-Hertz Limit: 8×10^7
Contact Life >105 operations at maximum signal level. >108 operations no load.1
