Fig. 4.14 CPU digital output example
This is an example of one of four programmable digital outputs
available from the KCM CPU pc board. This example is driving a
relay-CR.
Notes:
• Four programmable outputs are available.
• Functions are programmed as <CPUout1, CPUout2, CPUout3,
CPUout4>.
• A “low” output (sinking) condition = “true”.
• Maximum value of Vx = 40 Vdc. Maximum sink current = 100 mA
• Connections are made at the CPU pcb, terminal strip J8.
– CPUout1 = J8-6
– CPUout2 = J8-7
– CPUout3 = J8-8
– CPUout4 = J8-9

Fig. 4.15 CPU digital input example
This is an example of one of the four programmable digital inputs on
the KCM CPU circuit card.
Notes:
• Maximum current from terminal 3, +24 Vdc, all connections, is 350
ma.
• A low input provides an ‘ON’ condition with <Normal> polarity.
• Connections are made at the CPU pcb, terminal strip J8.
• Vin maximum = 24 Vdc
• Functions are programmed as <CPUin1, CPUin2, CPUin3,
CPUin4>.
