The Remote Access Controller/Universal Transformer Board fills the need to couple the dispatcher's train line to another line or couple a telephone line to an audio amplifier.  The RAC/UTB offers a choice of transformers, DC blocking capacitors, switch and relay pads and optional RJ25 style connectors to support almost any telephone to audio configuration. 

Options:

• Transformer for terminating a phone line or "dry" (no DC) audio connection
  
• Optional blocking capacitors on line 1 and 2
  
• Manual switch, relay or always in circuit
• Screw terminals and/or RJ25 (one connector per line or both lines on one connector)

See the application note for more details.

We offer the RAC/UTB as a bare board and in two assembled and tested configurations:

• Bare board
• Equipped with a Triad TY-145p (no DC) transformer, blocking capacitor and 8 position screw terminal. Use this configuration for coupling to an external amplifier
• Equipped with a Midcom 671-8208 (DC terminating) transformer, blocking capacitor on line 2, 24 Volt Relay for remote control of connection, and 8 position screw terminal.  Use this configuration for coupling a Dispatcher's Train Line to another line
