5000 Series Alarm Monitor

Access Instrumentation

Utilising the latest in microprocessor technology, the Access Instrumentation 5000 Series Alarm Monitor offers the end-user unlimited options for monitoring, recording and reporting on all categories of critical process systems.

The 5000 series Alarm Monitor will accept signals from a wide range of sensors and compare the measured value with pre-set alarm levels. If an alarm level is exceeded, the unit provides visual indication and relay closures, which can be used for alarm and shutdown functions.

Microprocessor technology is used to provide simultaneous measurement of all inputs and to carry out extensive internal self-checking procedures. Detected faults are indicated via the display and relay contact closure. The product has been designed for simple quick configuration.

The 5000 series alarm monitor is designed to replace the now obsolete Thermo – Rosemount 4000, 4001, 4002 & 4400 alarm monitors.

  • Available in 6, 12 and 24 channel models
  • High performance, flexibility and superior applications
  • Wide range of inputs and flexible output capabilities.

The 210 Loop Powered Indicator

Contrec Instruments

Overview

The 210 Loop Powered Indicator measures the current of a 4-20mA loop and provides a digital display of the process variable directly in engineering units. The indicator is powered by the 4-20mA loop and requires no external power.

Two potentiometers inside the instrument enable the Span and Zero to be scaled and a DIP switch enables the decimal point position to be selected.

Field mounting by design

The 210 indicator is fully watertight to IP67 (Nema 4X) standards. It is designed for field mounting with a wall mount bracket supplied as standard. A pipe mount bracket is optionally available.

For use in hazardous areas the Model 210i is ATEX certified, and CSAUS/C certified for both the USA & Canada.

Large LCD for easy reading

The 210 incorporates a large, easily read, 4 1/2 digit display. The measurement resolution is 3 1/2 digits and a trailing “0” can be switch selected for applications requiring 4 1/2 digits.

Each indicator is supplied with a sheet of self-adhesive engineering unit labels. A recess, adjacent to the display, is provided for the correct label to be placed. Applications include the display of flow rate, temperature, pressure and a wide range of other signals transmitted over a 4-20mA interface.
