DECS-250N Terminals and Connectors
Table 6. Right Side Terminal and Connector Descriptions
Locator Description
K A second DECS-250N connects through a standard serial cable to this DB-9
connector for the purpose of setpoint tracking. Setpoint tracking between a DECS-
250N and DECS-200N 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-250N 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.

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-250N 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 7 lists the acceptable wire sizes, strip lengths, and screw torques (compression terminals only) for
each terminal block. The locator letters used in Table 7 correspond to the locator letters shown in Figure
107 and Figure 108.
