Series 930 Fixed Gas Transmitter & Controller

Overview

The Series 930 Fixed Gas Monitor is a flexible monitor compatible with a range of gas sensors as well as a temperature and humidity sensor, if required. The sensor is housed in a robust IP65/NEMA 4 rated water resistant enclosure protecting it from water damage. There is also the option to include an integrated display for reporting real-time gas concentrations and/or an optional strobe and siren kit which can be configured to activate to a user defined set point.

The Series 930 outputs are designed to measure and control gas concentrations and communicate to a variety of hardware systems. The monitor can operate in three ways:

As a relay controller via the integrated relays and user configurable set points to control an external device such as an ozone generator or initiate an alarm.
As a gas transmitter via the 4-20 mA output which allows connection to a PLC or current sensing device to provide gas concentration information for applications such as health and safety monitoring.
As a monitoring network via the RS485 digital output to enable gas monitoring at several indoor locations with information being logged to a central point.

The Series 930 monitor is easy to install due to the lightweight enclosure and provided wall mounting kit. It requires a 24V power supply which is user supplied to allow flexibility in locations it can be installed.
