G100 Instruction Manual
D.20 Peripheral Types
D.20 Peripheral I/O modules are intelligent modules containing an on-board microprocessor. They are
configured as slaves to the G100. In this way, specific I/O processing is distributed throughout the to the
appropriate I/O module.
There are four types of I/O peripherals supported by the D.20 HDLC PCIe:
• D20A analog input
• D20S digital inputs
• D20K digital output
• D20C combination input/output
Optional high-voltage peripherals are also available.
Redundant D.20 communication channels are available on all peripherals. To utilize this function redundant
D.20 LAN cards are required to be installed on the D.20 Peripheral I/O modules. D.20 A, S and K Peripheral I/O
modules require 540-0207 and D.20 C requires 540-0209.
The D.20 HDLC PCIe card is only compatible with CCU BASE and PCOMMON v3.00 or higher.
Refer to Peripheral Compatibility with the D.20 HDLC PCIe card section in this manual for complete
list of D.20 Peripheral I/O compatibility.
For further information on I/O peripherals, see the D20/D200 Installation and Operations Guide (part number
994-0078); see section: Connections and Configuration.
