•Bypass” means to bypass the 100Ω in-rush resistor

that protects the reed relays.

NOTE:

•In this diagram and the table below, R represents “row,” and C represents “column.”

•“Bypass” means to bypass the 100Ω in-rush

resistor that protects the reed relays.

WARNING As a safety feature, interlock pins (17 and 33) must be shorted to enable the Analog Bus relays, which are on Matrix 2, to close. The optional 34933T-001 (for 2-wire) terminal block shorts these pins for you. This feature protects inadvertent routing of high voltages from the Analog Bus to the D-sub connector of the module.
