MacREJ 5

Product catalog summary
Overview: The MacREJ 5 is a digital data logger designed for natural gas stations, capable of recording various parameters such as gas pressure, volume, and temperature. It is suitable for use in hazardous explosive zones and can operate on batteries or external power for online data access.
Key Features:
  • Integrated 2G/3G/LTE modem for data transmission via TCP-IP connections.
  • Temperature-resistant 4” graphical display with backlight.
  • Operates in Ex zones 0, 1, 2 with up to 15 years of battery life.
  • Configurable via NFC standard with up to 7 independent measurement channels.
  • Supports NAMUR type sensors and universal GSM antenna connection.
Technical Specifications:
  • Data registration at 1-second intervals with extensive memory for hourly, daily, and monthly data.
  • Pressure sensors with various ranges and high accuracy.
  • Pt1000 A-class temperature sensor with compensated cable length.
  • Multiple digital inputs and outputs, including Ex programmable digital inputs and outputs.
  • Polycarbonate or metal housing with IP66 protection for outdoor installation.
  • Operates in temperatures from -25°C to 70°C with a relative humidity of up to 95%.
Communication and Interfaces:
  • Supports MODBUS RTU, MODBUS TCP, and other protocols on request.
  • Features optical and NFC interfaces for local readout and configuration.
  • Includes two independent serial transmission ports with high-speed data transfer.
Accessories:
  • eWebTEL Software: A platform for data aggregation and visualization, enabling comprehensive supervision over the gas network.
  • EM-1 Extension Module: Adds current and relay outputs, operable as a standalone device with remote modification capabilities.
  • INT-S3 Transmission Interface: Provides external power supply and data transmission via RS485 port.
  • OptoBTEx Interface: A wireless Bluetooth transmitter for data from compatible devices.
  • EM-2 Extension Module: Adds digital inputs and operates as a standalone device with remote modification capabilities.
Additional Information: The document also includes details on the GSM/GPRS antenna specifications and the MacREJ 5 application scheme for data transfer and local readout.

INT-S3 | Transmission interface Performs as an external power supply to the intrinsically safe measurement device (located in stationary telemetric systems supplied from 11V-30V DC or a battery that is located in explosive zone 0, 1, or 2). Additionally, data is transmittable to a readout device (i.e. computer) via RS485 port. EM-1 | Extension module Extends the functionality of MacREJ 5 by adding two additional current outputs operating in 4-20mA current loop and four binary relay type outputs. Can operate as a standalone device as it has its own parameters that can be modified remotely using...
