Operating Instructions OW-503-4 4 Channel Power Switch www.orangewiresystems.com... - Page 2 (I < 100mA), a high accuracy shunt provides microamp current sense data to measure battery drawdown. The OW-503-4 is designed for the National Instruments (NI) Switch Load Signal Conditioning (SLSC) system, to be used in Hardware-In-the-Loop (HIL) simulators. This card is used to test prototype or production Electronic Control Units (ECUs or ...

Page 6: Front Panel Connections
Signal Description OW-503-4 has four relays on it. All four relay common terminals are connected to the “IN” pins. All “IN” pins are connected to each other. Relay normally open pins are connected to the ”OUT” pins. “COM” pins are connected to each other, and are not switched. ... -

Sleep Mode Current OW-503-4 has 4 channels, each with a so ware enabled 10Ω shunt for detecting current when the DUT is in power-down or “sleep” mode. Each shunt has a positive and negative end, and both ends are available on the rear panel and can be connected to a fully ... - Page 8 Pinouts Signal Midplane Pinout for OW-503-4 (Identical for all 12 card positions) *Lab Ground if PXI jumpers on OW-503-4 are connected. www.orangewiresystems.com...

Page 9: Reference Connections
Reference Connections OW-503-4 brings all 8 references from the OW-130 Signal Midplane. Jumper wires are used to make connections between the IN, OUT, or COM signals and the Signal Midplane Reference Rails. To switch power to a Midplane Reference Rail, connect the output ... - Page 10 www.orangewiresystems.com...

Page 11: Theory Of Operation
Theory of Operation OW-503-4 is designed to switch power to devices under test, or to the Signal Midplane power rails. Each channel has a 40A, so ware enabled relay. Relay common for all channels is connected to the IN net. Relay normally open is connected to the output ... - Page 12 PXI Jumpers The OW-503-4 can be used with multiple real time NI Analog to digital conversion modules and multi-meters. Because many of these modules have di erent pinouts and grounding patterns, the OW-503-4 has jumpers B1-B3 to enable compatibility with all ...
