40-199-002 Fault Insertion Switch Schematic
Diagram. This version has 2 fault buses, the
40-199-001 has 1 fault bus
The 40-199 is a 10 Channel Fault Insertion switch designed for the
simulation of fault conditions in automotive/avionics applications,
involving the reliability testing of safety critical controllers.
It is designed to be able to insert different fault conditions between
the test xture and the equipment under test:
• Open-Circuit
• Short-Circuit between UUT connections
• Short-Circuit to other signals such as Power, Ignition & Ground
via Fault Insertion Bus
Through relays on each channel enable signals to be held open-
circuit. Fault insertion buses allow channels to be shorted together
or to be connected to an external fault condition such as power,
ignition or ground. The module is available with either 1 fault bus
(40-199-001) or 2 fault buses (40-199-002).
The 40-199 uses high quality electro-mechanical power relays with
10A hot or cold switching capability. All relays are normally open
types. The fault buses are rated at 20A in order to allow two 10A
fault connections to each bus.
