Multi-Channel Load Cards
Data Sheet
Figures 1, 2 and 3 below exhibit Keysight Technologies, Inc. TS-5000 family load cards are a cost-effective and
circuit diagrams on how single, reliable set of multi-channeled load cards designed speciically for automotive
dual and quad-load load cards functional testing.
function respectively.
It offers a wide range of load cards with up to 48 addressable channels, covering
from low resistance to high current. The high current load cards offer lyback
protection while utilizing reliable reed relays with power bus to supply power to load.
The TS-5000 family offers single, dual and quad-load load cards, each allowing
you to connect to internal and externally deined load values.
The multiple types of load cards offered are categorized as follows:
Figure 1. Single-load
Single-Load Load Cards
E6175A: 8-channel, single-load
E6176A: 16-channel, single-load
E6177A: 24-channel, single-load
E6177B: 24-channel, single-load
E6178A: 8-channel, single-load
Dual-Load Load Cards
N9377A: 16-channel, dual-load
N9379A: 48-channel, dual-load
Figure 2. Dual-load
Quad-Load Load Card
N9378A: 24-channel, quad-load
The TS-5000 family load cards work well with Keysight E6198 programmable
Switch/Load Unit (SLU), with up to 21 slots of optional Keysight plug in cards.
This programmable SLU can also be used for instrumentation switching, as well
as switching power supply and loads to the electronic control module (ECM).
With the TS-5000 family load cards, your test engineers can choose their own
load devices for any speciic testing requirement that they may have.
A lexibility like this allows the application of loads that are more than
just resistors, for example, reactive loads with inductors or capacitors
Figure 3. Quad-load
can also be itted for an ECM application that requires emulation.
The TS-5000 family load cards also have the ability to provide lyback
protection for high current handling.
