DESCRIPTION
The YAV904X8 module contents 32 DPST Relays forming four banks of 2-Pole 1 to 8 ports. All
bank common pins are connected to a twin contact, which makes it easy to re-configure for the
following options:
•
4 x (1 to 8)
•
2 x (1 to 16)
•
1 x (1 to 32)
•
2 x (1 to 8) + 1 x (1 to 16)
•
1 x (1 to 8) + 1 x (1 to 24)
Joining two or more YAV904X8 modules the multiplexing can be increased until all test
requirements are covered.
This module is designed for the isolated switching of DMM signals. In case the system requires
high precision measurements, a two branch matrix can be configured, allowing 4-wire
measurements (resistors) and bridge excitation and measuring (for example load cells).
The board is organized in 4 groups of 8 bipolar relays, with double contact access to each
branch. Therefore, there is the possibility to set up different multiplexer configurations, adding
wiring connections inside the test fixture:
Set up
1 x 32 relay multiplexer
2 x 16 relay multiplexer
4 x 8 relay multiplexer
2 x (8 relay + 16 relay multiplexer)
1 x (8 relay + 24 relay multiplexer)
.
