ContactAgent
  • Remote site monitoring and control for generators
  • Provide network access for non-network equipment via web and SNMP
  • Email Alarm Capability
  • Contact Closure or Analog Inputs and Latched Relay Contact Outputs
  • Optional Temperature and Humidity Measurements


ContactAgent is a modular remote monitoring and control system. The system consists of the Master Unit, Remote Input Module (RIM) and Remote Output Module (ROM). The Master Unit has built-in capability to monitor up to eight digital contact-closure inputs, plus the ability to control two contact-closure outputs. The capability of the Master Unit can be easily expanded through the use of RIM and ROM slave modules placed at the point of use and connected to the Master Unit with common CAT-5 Ethernet cabling.
General
Each of up to four additional RIM modules adds six additional monitored inputs to the system, plus local AC utility power monitoring and optional point-of-use temperature and humidity sensors. Each RIM input can be programmed to respond to contact-closures or it can measure analog voltages. When programmed as analog monitored points, each input has a DC measurement range of +/- 12Vdc with accuracy of +/- 2% and measurement resolution of 25mV. A special RMS analog mode allows an input to measure 50-60Hz AC voltages of arbitrary waveform.
Each of up to four additional ROM modules adds four additional remotely controllable Form-C relay contacts. The relays are mechanically latched, so they maintain their state during a system power loss. The ROM also contains optional point-ofuse temperature and humidity sensors.
The ContactAgent system is fully programmable and remotely operable via either the built-in web pages or via its industry standard SNMP interface. All inputs can be individually configured to generate alarms under user-defined conditions, and an email client can be configured to send alarm messages to up to three email addresses.
Point of Use Architecture:
ContactAgent’s modular and expandable architecture lets you place measurement modules close to the device that they monitor or control, simplifying wiring, minimizing false triggering from local noise sources and optimizing the reliability of the installation.
Web-Based Configurations and Control:
ContactAgents built-in web server allows you to configure all monitoring modes and alarm thresholds easily and intuitively. Digital (contact) inputs can be individually set up to make alarms on state changes, and the ‘normal’ and ‘alarm’ states can be user-defined. Analog inputs can be bracketed by alarm thresholds.
User-Defined Analog Scaling:
Each analog input can have individual user-defined scale factors applied. For example, an input that varies from 10 to 12 Vdc can be made to display in user-definable scaleable units such as “5.7-9.5 dB”.
Fail-Safe Relay Outputs:
The ROM module’s controllable FORM-C relay output contacts are mechanically latched, to prevent a change in the contact state during a loss of power.
SNMP Interface:
ContactAgents industry-standard SNMP interface gives you complete control to monitor and manage installations and equipment without locking you into proprietary software. Most SNMP compliant manager software can easily be made to work with ContactAgent.
