Enhanced Contractor Board Connections
The Enhanced Contractor Board is available as an option. This expanded version allows for additional
connection points of previously discussed interfaces as well as additional high end interface options
(Figure 12).
Note: Remote relays can accept dry contacts rated up to 2A/250V.
The Contractor Boards have multiple applications in PDI products and not all connections are supported
on the STS 2000A. The following connections are not currently supported on this product:
•
Inter-Range Instrumentation Group (IRIG) time codes
•
Cell-phone modem connection
5.1.3
Modbus RTU Connection
The STS has an isolated RS422/RS485 Modbus RTU interface with soft bias provided. Both Contractor
Boards have external connections for RS422/RS485. The Modbus interface can be configured for baud
rate, parity, and address on the
Settings
screen (See
9.1 Settings Screen.
). The address range is 1 to
255 and the address of each device must be unique. Jumpers on the monitor circuit board select either a
2-wire or 4-wire configurations for connection.
5.2
Ethernet Connection
The Monitor PCB has an Ethernet port and cable. The Ethernet cable hangs down from the Monitor with a
an RJ45 jack connection that is close to the Contractor Board.
Use the
Settings
screen to set Ethernet parameters (
10.2 Ethernet
). The Ethernet connection allows you
to run TCP/IP, Modbus TCP/IP, HTTP for the web server, SNMP, SNTP for time synchronization, and
SMTP for email summary alarm alerts. Chapter
10 System Setup: Networking
describes configuration
for these options.

Dry Contact Output Signals
Contractor Board remote relays signal status and alarms through closed dry contacts, shown in Table 1.
There are three predefined relay lists. Remote relays can be customized during setup to turn on for other
points in the STS points list.
