The CPC400 has the following features:
• Keypad and two-line, 16-character display.
• Screw terminals for the power and analog inputs and
communications.
• Input power of 12 to 24 V Î ( dc) at 1 Amp.
• 50-pin SCSI cable to connect the digital inputs and
outputs to the 50-terminal block (TB50). The CPC400
is available with an 18-terminal block (TB18) in place
of the SCSI connector, as shown in Figure 1.3 on page

• Nonvolatile flash memory for storage of firmware and
programmable logic.
• Battery-backed storage of operating parameters. If a
power loss occurs, the operating parameters are stored
in memory. The battery has a ten-year shelf life, and
it is not used when the controller is on.
• Microprocessor control of all calculations for input sig-
nal linearization, PID control, alarms, and communi-
cations.
