D20/D200 Technical Overview

D20 High-Voltage Peripherals

D20 high-voltage peripherals provide an extra level of protection for your system. They are
packaged similar to the standard D20 I/O peripherals, but the input and output circuits are
conditioned to handle higher voltages. For instance, the high-voltage version of the D20S, the
D20 SZ, supports ON thresholds of up to 220 VDC. For more information, see section 2.4, I/O
Peripheral.
D20K4Z Termination Module
The WESTERM D20K4Z is the termination panel for the D20K4Z high-voltage control output
module. As well as providing outputs that can withstand higher voltages, all of the control relays
on the D20K4Z termination module are 4-pole, momentary contact, so that both sides of an
interposer coil can be switched for additional control security. For more information, see section
2.4, I/O Peripheral.
New Power Supplies
GE Grid Solutions has introduced several new D20/D200 power supplies that provide additional
capacity and improved standards compliance. The new power supplies are designed to be drop-in
replacements for the existing D20 power supplies. As shown in the following tables, each of the
existing power supplies has two possible replacements, one with a 24 V isolated output, and one
with a 48 V isolated output. For more information, see section 2.5, D20/D200 Power Supplies
and Chargers.
