34959A Breadboard Component Module
Use this module to create your own custom designs inside the 34980A mainframe. You can control your
custom circuits with access to both the +12 V and +5 V supplies, 28 relay drive lines, and two 8-bit GPIO
ports. Your design can be isolated from the analog buses or connected by loading the backplane
switches. Simply mount your custom PC board or other components into the space provided and connect
via the two ribbon connectors provided. The module is provided with two 50- or 78-pin Dsub connector
openings. For custom connections, use the detachable flat faceplates for easy modification. You can
program your circuitry using standard read and write commands in SCPI.

34959A breadboard component module conditions of acceptability:
1. Follow local laws and regulations provided by the Authority Having Jurisdictions (AHJ). This
equipment is Certified as a component for use in other CSA Certified equipment where the
suitability of the combination is to be determined in the end use application.
2. When interconnecting the 34959A component module to the system components during installation,
the overall 34980A and all installed modules for the system and their maximum rated allowable
inputs default to the lowest rating of any one system component or module.
3. With *hazardous voltages anywhere in the overall 34980A and all installed modules use only female
D-Sub output connectors Keysight Part Number DB-50(F) 1253-5854 or DB-78(F) 1253-5007.
33
4. With only *non-hazardous voltages in the overall 34980A and all installed modules use either
female D-Sub output connectors Keysight Part Number DB-50(F) 1253-5854 or DB-78(F) 1253-
5007, or male D-Sub output connectors Keysight Part Number DB-50(M) 1253-5853 or DB-78(M)
1253-6006.
5. Install overcurrent protection with devices rated or the snubber circuits to limit the current according
to the 34959A Current Limiting Graph located in the User’s Guide.
6. Install only Keysight supplied relays 0490-1954 when connecting to the Analog Bus.
*Any voltages greater than 30Vrms, 42.4 Vpeak and 60Vdc are considered hazardous (IEC 61010-1).
Available space for internal board/components: 5.4 x 7.5 x either 0.9 inches in height without PC board or
0.7 inches high with a PC board.
