Connecting the Prototyping Board to the BL1600
Connect the Prototyping Board to the BL1600 by pressing the five header
blocks underneath the Prototyping Board onto the corresponding header
pins of the BL1600. The headers on the BL1600 and the Prototyping
Board have the same names: H1, H2, H3, H4, and H5.
Power Supply
The power (24V) for the Prototyping Board is obtained from pin 4 on the
PLCBus (header H5). Two LM340 series regulators, shown in Figure C-2,
regulate the voltage at +15 V, 15 V, and +5 V:
The output tolerance of the regulators is ±2% at 25°C and ±4% over the
BL1600s operating temperature range. The complementary 15 V comes
from a Harris ICL7662 voltage converter input from +15 V.
