1. GENERAL INFORMATION
1.1 DESCRIPTION
The SDTA-02 is an interface accessory that converts AC voltage and current signals into an
AC signal compatible with MULTITEL monitoring systems.
The following list shows the eight possible configurations available for the SDTA-02 interface.
Table 1 – SDTA-02 Models and Part Numbers
DESCRIPTION MULTITEL PART #
SDTA-02, 240 VAC 3 phases M-4173*
SDTA-02, 600 VAC 3 phases M-4178*
*These models are CSA and CSA “US” approved.
For current measurement (0-1000A), current transformers are used to provide the 0-5 Amp
output signal required by the current input interface.
For voltage measurements (0 to 240 VAC and 0 to 600 VAC), three (3) voltage input
interfaces are provided, each with a 2-wire input connection.

3. OPERATION
3.1 GENERAL
The SDTA-02 is designed to transform high-AC currents and voltages into a current or
voltage scale compatible with analog channels on MULTITEL’s monitoring systems,
such as the RPM-1000/C, the MXP2 188 and the MIRADOR.
3.2 ANALOG CHANNEL SETUP
The SDTA-02 will send its measurements to several analog channels on your
MULTITEL monitoring system. In order to operate properly, those analog-input
channels need to be programmed with the proper scaling factor according to the AC
voltage or AC current input range (see Table 2). Please refer to the user’s manual of your
MULTITEL monitoring system for a complete description of steps to follow in order to
configure it accordingly.

3.3 MULTITEL MONITORING SYSTEM CONFIGURATION SETUP
The SDTA-02 has been set in the factory according to your needs. However, you should check
that setting is correct in order to avoid erratic readings (see the following table).
