RCM-124 IP Controlled Relay Module

The RCM-124 IP Controlled Relay Module provides a robust method of controlling remote audio, telephony, or other low-power circuits. When installed on an Internet Protocol-based network, users can remotely control any of these low-power devices using their own custom applications or a standard web browser.

RCM-124 Features

High quality, gold contact relays provide long-life and quiet switching that is necessary for audio and telephony applications
24 differential channels/lines of control per unit can interface directly to analog telephone stations, call control platforms, or other low-power circuits
Provides onhook/offhook station-side detection for all 24 channels
Positive ‘state’ feedback status can be read from each line driver to ensure that controls are in the proper state
The RCM’s Internet Protocol interface allows a variety of control protocol options including TCP/IP, UDP/IP, or browser-based web interfaces
Can be physically located on any LAN or WAN that supports Ethernet IP
Standard 25-pair telephony connections to the outside world include pass-through connectors for ease of installation
Small device footprint can easily be mounted on most telephone room backboards
System software can be upgraded in the field through the craft port
