• Manufacturer Part Number: 101-0738
• Description: CARD ETHERNET 512K SRAM SR9150
• Manufacturer: Rabbit Semiconductor

Specifications of 101-0738

• Accessory Type: Smart Star CPU Card
• For Use With/related Products: SR9150
• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

The protected digital inputs, shown in Figure 27, are factory configured with 10 kΩ pull-
up resistors. Digital I/O cards are also available in quantity with the protected digital
inputs pulled down as shown in Figure 27.
A 0 Ω surface-mount resistor is used as a jumper to select whether the inputs are pulled up
or down, as shown in Figure 28.
The digital inputs are able to operate continuously from -30 V to +30 V, and have a logic
threshold of 2.5 V. They are protected against spikes up to ±48 V.
