Features

The TC8612 offers a simple and effective solution for transporting dry contacts over T1/E1, replacing complex T1/E1 channel banks for small scale applications and providing a plug and play solution. It’s economical, easy to install and comes standard with built-in power redundancy and extensive diagnostics.

The TC8612 transports bi-directional dry contacts that typically link up RTUs, Relays, Controllers, Telemetry and other equipment with Digital I/Os.

Diagnostics include DIP switches for Local & Remote Loopback and other application configuration switches. Each unit also provides multiple LEDs for Alarm, Power, Vcc, T1/E1 Status, and RLY & DET status LEDs for each channel.

  • 8 Channel Bi-directional Dry Contact
  • Very Low Latency – 1.5ms
  • ESF Framing Support for T1
  • PCM30C Framing Support for E1
  • Isolated Ground for Detectors
  • Supports 120Ω & 75Ω E1
  • Built-in Power Redundancy
  • Rack Mount or Stand Alone
  • Optional “Dry Contact Status Hold”*
