Section 1 - Technical Specification
Updated Product Information
The 40-575A and 40-576A have been introduced as a “form & fit”
update to the 40-575 and 40-576 respectively, the changes are to
provide an updated bus interface which will require the use of an
updated software driver. Otherwise, the electrical performance is
very similar and the pinout is identical.

eBIRST switching system test tools simplify switching system
fault-finding by quickly testing the system and graphically
identifying the faulty relay.

The 40-575A/576A/577/578/579 are a range of high density
matrix modules able to switch up to 2 A or 300 VDC/250 VAC.
They are constructed using high quality electro-mechanical
relays for high switching confidence.
The range is as follows:
• 40-575A-001 84x4, 1-Pole Matrix
• 40-576A-001 64x6, 1-Pole Matrix
• 40-577-001 50x8, 1-Pole Matrix
• 40-578-001 36x12, 1-Pole Matrix
• 40-579-001 28x16, 1-Pole Matrix
The modules are designed for switching medium voltage
and power signals. The user signal connection is via a
robust 160-pin DIN 41612, 78-pin D-type or 50-pin D-Type
connector that is fully supported by the wide range of
Pickering Interfaces cable and connector accessories.
Relay Cycle Counting
To aid with module “health” monitoring, the 40-575A and 40-576A
are provided with a relay cycle counting cycle feature. The
number of operations per contact are stored on the module and
can be used to determine if a relay is approaching EOL. This
information could allow system connections to be revised so that
signals applied to heavily used contacts are swapped with lightly
used contacts to prolong the working life of the relay(s).

Section 1 - Technical Specification
Matrix Functionality
The 40-579 permits 14 concurrent X to X paths or 16 concurrent Y to X paths, the 40-575A, 40-576A, 40-577 and 40-578
permit 4, 6, 8 and 12 concurrent X to X or X to Y paths respectively. As an example, the 40-575A is shown in the figure below;
X to Y connections (e.g. X59 to Y3) and X to X connections (e.g. X5 to X27) are permitted, also any number of X connections
can be connected to the Y axis (e.g. X3, X18, X22 & X66 to Y2). However, the driver prevents the connection of Y axis
connections together (e.g. Y1 to Y4).
