A 1771-KA2 module gets its power from the backplane. It requires +5V
DC at 1.2 amperes (max.). The following power supplies are compatible:
System power supply (cat. no. 1771-P1)
Auxiliary power supply (cat. no. 1771-P2)
PLC-2 system power supply module (cat. no. 1772-P1, series B or
later)
PLC-2 auxiliary power supply (cat. no. 1777-P2, and 1777-P4 series B
or later)
Modular power supplies (cat. no. 1771-P3, -P4, -P5)
You must connect one of these supplies to the I/O chassis that contains the
KA2 communication adapter module. In a Mini-PLC-2, or a
Mini-PLC-2/15 this is the system power supply, shown in Figure 2.7. In a
Mini-PLC-2/05, you must use a 1771-P3, -P4, or P5 power supply.
