Sentry IT 32 Channel Controller
Sierra Monitor's Sentry IT 32 Channel Controller is a powerful network-enabled hazardous gas detection system controller that can operate up to 32 detectors and interface with devices over Modbus RTU, analog 4-20 mA, Sentry PSG Bus, and conventional dry contact. As part of the Sentry IT line, the Sentry IT Controller is compatible with the Classic Sentry, Sentry IT detectors, such as the 5100-XX-IT series, and other third party sensors and devices.
With its modular internal design, users can select just those I/O components that are needed for their application without adding multiple external boxes. The Sentry IT controller's large, touch sensitive, and easy-to-read color panel, along with a simple menu-driven configuration approach makes it easy to configure and operate the system. In addition, the controller easily integrates with plant-wide distributed control systems, PLC's, personal computers, tablets, and smartphones to provide the necessary data and alarms. The embedded Web application enables management and technicians to view important data remotely and provides connectivity into the Industrial Internet of Things (IIoT).
