DC Power Switching Device
Three separate Ports

* Remote Control over standard telephone line
* Local Control through a standard RS-232 Port

DC3-TT Front Picture DC3-TT Back Picture

The DC3-TT is a DC power switching device, used to open or close relays on each on the three "Out Ports" on the unit. It is normally used to control the power to up to three other DC power devices, ON/OFF/RESET.

It operates at DC voltages from 7V to 30V. The "Out Ports" (Controlled Ports) are rated at 10 amps. This can assigned to one port or split between the three ports.

Both the input and the output connections are made through stripped wire terminal lugs (16-24 AWG). The DC3-TT itself consumes less than 1 W of operating power.

It can be controlled remotely over a standard telephone line (land or cell) using a standard Touch Tone key pad. It is password protected and can share the telephone line with other standard telephone devices. The key command entries can also be automated using a standard modem and AT dial string at the dialing end even though there is no modem at the controlled end.

The DC3-TT can also be controlled locally through a local RS-232 port (filtered adapter required). The RS-232 port can also be used to change some of the operating parameters. TTL logic level control can also be provided on custom units (0-12V.) (+ = ON / 0 = OFF).

You can also make inquires as to the status of power (relays) or the set up configuration. The responses are in "beeps" over the phone lines or a screen display with RS-232. Either of the two methods may also be used to change the touch-tone password as well as other operating parameters (local or remote). Both methods of control may be used simultaneously.

Up to ten units can be daisy-chained together using RS-232 control or put multiple units on the same telephone line with different passwords, using touch-tone control.
