Description
K
A second DECS-250 connects through a standard serial cable to this DB-9 connector
for the purpose of setpoint tracking. Setpoint tracking between a DECS-250 and
DECS-200 is possible.
L
This DB-9 connector is provided for PROFIBUS communication (style xxxxxxP) and
the future implementation of other communication protocols. Contact Basler Electric
for protocol availability.
M
Three terminal sets within this block include two CAN communication ports and an
IRIG input. The IRIG terminals connect to an IRIG source for synchronization of
DECS-250 timekeeping with the IRIG source. Both CAN ports are SAE J1939
compliant. CAN 1 is used to connect add-on modules such as the Basler Electric
CEM-2020 and AEM-2020. CAN 2 is used to communicate with a genset engine
controller.
The terminal numbers (shown below) are located on the mating side of the
connector.
• 96 - CAN 1 High
• 97 - CAN 1 Low
• 98 - CAN 1 Shield
• 99 - CAN 2 High
• 100 - CAN 2 Low
• 101 - CAN 2 Shield
• 102 - IRIG +
• 103 - IRIG –
N
This optional Ethernet communication port uses the Modbus TCP protocol to provide
remote metering, annunciation, and control. A copper (100Base-T) port (style
xxxxx1x) uses a standard RJ45 jack while a fiber optic (100Base-FX) port (style
xxxxx2x) uses two fiber optic connectors (not shown).
Terminal Types
Spring terminals are supplied on DECS-250 controllers with a style number of xxxSxxx. These removable
connectors secure each wire with a spring-loaded contact.
Compression terminals are supplied for the operating power terminals (locator A), field power output
terminals (locator B), and current sensing terminals (locator C) when a style number of xxxCxxx is
specified. The remaining connectors use spring terminals.
Table 18-3 lists the acceptable wire sizes, strip lengths, and screw torques (compression terminals only)
for each terminal block. The locator letters used in Table 18-3 correspond to the locator letters shown in
Figure 18-1 and Figure 18-2.
