3.7 Telemetry Connections

TTC-1000 provides a 9 pin female subminiature D connector on all models.
Panel mount models can either have analog outputs or an RS-485 interface for
DNP3.0 or MODBUS communications. NEMA 4 models can be equipped with
both analog interfaces and an RS-485 interface for DNP3.0 or MODBUS
communications.
3.7.1 RS-232 Terminal Connections
Connection to this interface is through the front panel mounted DB-9 connector.
When connecting to a standard RS-232 port in a PC, either desktop or laptop,
use a 9 pin female to 9 pin male null modem cable. The following table lists the
pin connections to the DB-9 connector.

3.7.2 Analog Outputs

The TTC-1000 is available with up to three analog outputs configured as current
loops. The source for each analog output can be selected from probe 1 (P1),
probe 2 (P2), or calculated winding temperature. The analog output is designed
to operate with a maximum series resistance of 10,000 Ohms when set to 0 to 1
mA or 510 Ohms when set to 4 to 20 mA.
NEMA 4 models equipped with a plug-in analog output module utilize TB5 for
connections to the analog outputs. The panel unit has TB5 on the back panel.
Connections to TB5 are shown in Figures 3.15a & b. The terminal marked + is
the current source output. The connection marked – is the current transmitter's
return and is isolated from chassis ground within the TTC-1000.
