Jackrabbit (BL1800)
3.2.2 Digital Outputs
The Jackrabbit has four CMOS-level digital outputs, PB6–PB7, PCLK, and IOBEN. Four
high-power outputs, HV0–HV3, are also available—HV0–HV2 can each sink up to 1 A
(200 mA for the BL1810 and BL1820) at 30 V, and HV3 can source up to 500 mA (100 mA
for the BL1810 and BL1820) at 30 V. The BL1820, which does not have RS-485, has one
additional CMOS-level digital output, PC0.
Figure 6. Jackrabbit High-Power Digital Outputs
The common power supply for the four high-power outputs is called K, and is available on
header J4. Connect K to the power supply that powers the load, which is usually a separate
power supply to that used for the Jackrabbit, and must be no more than 30 V because of
the power limitations of the resistors used in the sourcing output circuit.
The K connection performs two functions.
1. K supplies power to the sinking/sourcing transistors used in the high-power circuits.
2. A diode-capacitor combination in the circuit “snubs” voltage transients when inductive
loads such as relays and solenoids are driven.
