3.2 - Basic Board

The PD4 - Basic board is 24VAC power supplied. It contains 8 Discrete Inputs (Switch type), 8 Digital Outputs (5
triacs and 3 relays), 10 Analog Inputs (five thermistors and four pressure transducers) and 1 analog input (0-10
Vdc) . See the schemes in Appendix E. The software is contained in a Flash EPROM (downloadable only with
Downloader). All the setpoints, runtime and configuration parameters are contained in an EEPROM (data
storage at power down).

3.2 - CCN/Clock Option Board (factory installed)
The PD4 - Global chiller controller has a small option board that can be connected to the Basic Board via a
single 10 pin header and 4 metal standoff. This option board contains one RS-485 driver for CCN
communication, a real time clock and super cap for two weeks backup. There are two connectors for CCN. One
is a 3 pin screw connector ( 1= + signal, 2 = ground signal, 3 = - signal) and the other is a 6 pins phone jack.
