Lynx50 is a high speed CAN controlled solid state relay (SSR) multiplexer used to switch differential signals. It is suited to supply multiple boards in a sequential way, or to multiplex CAN control signals, so that test cost and complexity are reduced. Due to its internal design, each DUT pin can be addressed to any of the following contacts: · Backplane + · Backplane – · Bypass from PIN to PIN at the same connector. · Analog input. · Digital input. BLOCK DIAGRAM TEXT Board size: 295 x 100 mm. Rackable board for 19” subracks. Expandable when combined with Lynx backplanes. CAN and USB...

Lynx50 is a good choice for the ICT testing of low input/output DUT circuits for any of the markets listed below: DUT: Device Under Test. SSR: Solid State Relay. FID: Function Injection Device (device used to activate any DUT IO pin a certain signal with the objective to validate the associated function, e.g. digital input, analog input or power output). BKP: Backplane. DDM: Digital multimeter. DI: Digital input. AI: Analog input. Automotive. Industrial. Telecommunications. Medical devices. PLC emulation. Automation. Control for visual inspection systems. Impedance and short circuit...

Supply multiple boards in a sequential way. When a power supply is connected to the backplane we can supply multiple DUT’s in a sequential way. External devices activation. Any external device can be activated to execute a desired action. In the example a DC motor is activated for marking the DUT PCB.

PINOUT PINOUT: Lynx53 has 4 connectors. • J1: Connection with the standard interfaces of the Lynx Tester backplane modules. • J2: Use this connector for injection of primary signals used for the EOL test. • J3. USB standard connector. • J4: Use this connector to connect with the DUT.

RELAY SWITCH MATRIX The following table indicates the way the relays are internally connected. Some examples are described below to understand the table: • J4:1 is a channel which is connected with the DUT. • U2 connects the J4:1 signal to the pin BKP+ (J1:8). • U20 connects the J4:6 signal to the pin BKP- (J1:7). • U38 bypasses the signal from the pin J4:44 to the pin J4:11. • U48 bypasses the signal from the pin P1:1 to the pin P1:2. • AI1 is an analog input connected to the pin J4.34. • DI1 is a digital output connected to the pins J4.44 and J4.11.
