This Field Mounted Monitor is a multipurpose monitor designed to detect Single, Toxic gases or Oxygen in Ambient Air. It is available with a combination of simplicity and performance. This durable NEMA 4X or 7X assembly is ideal for a variety of commercial, industrial and general purpose applications.
Model GD 250 single channel digital control module is developed to show the status of any single integral assembly. This is covered with NEMA 4X wall mount or Ex proof enclosure. It is available with modern controllers interface having two or three wire 4-20 mA sensors or standard voltage / current sensor transmitters. It ensures to provide concentration display as well as independent adjustable alarm levels. This comes with 3 ½ digit LCD or Graphical LCD display that is designed to easily read the concentration. LEDs on the front panel ensure to offer indication of three alarms and the relays can be easily programmed for latching or non-latching activities. SPDT Form C type rated relays with 5 Amps are available to provide direct alarm action as well as minimize interposing relays demands. With local alarm devices, it can be connected to the board alarms. In addition to this, Fail Safe Supervisory features ensure to provide reliable indication of fully operational monitor. Its design shows the input power along with the status of the power supply for the amplifiers. If any of these functions fail, it illuminates a Fault Light Emitting Diode.
