Agilent Technologies (HP) HP 34938A / 34938T

20-Channel General Purpose Switch Module for 34980A The Agilent 34938A General Purpose Switch Module has 20 5-amp channels in a Form A topology used with Agilent 34980A Multifunction Switch/Measure Unit. Each Form A general-purpose switch can handle up to 150 W, enough for many power line-switching applications. Each Form A general-purpose switch can handle up to 150 W, enough for many power line-switching applications. The built-in relay counter helps predict when relays need to be replaced. The general purpose switch module contain latching armature relays where multiple channels can be closed at the same time. Additionally, for switching reactive loads, the optional terminal blocks have pads for snubbing circuits. Agilent / HP 34938A Features 20 Form A channels up to 5A, 150W 30 VDC / 250 VAC 5 A switch (8 A carry) Armature latching relays, with relay counter Temperature sensor for overheating conditions Simultaneous channel switching With 34938T
