MICRA-M MAX Overview

MICRA-M MAX is a versatile instrument equipped with Webserver, Bluetooth, and MQTT capabilities. It can be configured for various types of inputs:

  • Process Input: Voltage (V), Current (mA)
  • Load Cell Input: Millivolt (mV)
  • Pt100 Input
  • Thermocouple Input: Types J, K, T, N

Basic Instrument Set

The basic instrument set includes:

  • Motherboard
  • Programmable tricolor display
  • Power supply
  • Ethernet communication option

Standard Features

The MICRA-M MAX offers a range of standard features:

  • Reading of input variables
  • Remote hold functionality
  • Reading and memorization of maximum and minimum values (peak/valley)
  • Tare and reset functions
  • Comprehensive programmable logic functions

Output Options

Various plug-in output cards can be installed to enhance the system:

  • RS232C Serial (RS2)
  • RS485 Serial (RS4)
  • Ethernet (included in the basic model)

All output options are optoisolated from the input signal and power supply.

Control Options

The MICRA-M MAX supports multiple control output options:

  • NMA: Analogue 4-20mA
  • NMV: Analogue 0-10V
  • 2RE: 2 Relays SPDT 8A
  • 4RE: 4 Relays SPST 5A
  • 4OP: 4 NPN outputs
  • 4OPP: 4 PNP outputs

Communication and Configuration

The MICRA-M MAX incorporates several communication and configuration features:

  • Webserver: Allows initial setup with login and provides instant readings of measured variables.
  • Bluetooth: After downloading the Ditel Connect application, the instrument can be configured via a Smartphone.
  • MQTT Protocol: Enables communication with an MQTT server.
  • REST API: Facilitates communication and data exchange between different systems. This includes:
    • MICRA-M MAX API (Specifications)
    • MICRA-M MAX API (Settings)
    • MICRA-M MAX API (PHP Functions)

Packing Contents

  • Quick start guide for the panel meter
  • Digital panel meter MICRA-M MAX
  • Accessories for panel mounting (sealing gasket and fixing clips)
  • Accessories for wiring connections (plug-in terminal block connectors with a fingertip key)
  • Wiring label affixed to the MICRA-M MAX case
  • Four sets of labels with engineering units

Programming Instructions

The instrument features software that allows configuration through its keyboard, providing access to independent programming menus for input, display, and logical functions. If additional options are installed (communication outputs, analog output, and relay output), they are automatically recognized by the instrument and activate their own programming software.

Programming can also be performed via a PC using the built-in webserver and configuration API, or through Bluetooth on a Smartphone using the DITEL Connect APP, which can be downloaded from our portal: micramax.ditel.es.

Programming Lock-out

Total or selective lock-out of programmed parameters can be managed via the webserver or the local keyboard. The instrument is shipped from the factory with unlocked programming, allowing full access to all programming levels by the operator.

Dimensions and Mounting

The figure below shows the locations of the different output options available.

The 2RE, 4RE, 4OP, and 4OPP options are alternative, and only one of them can be installed in the M1 connector.

The RS2, RS4, and ETH options are also alternative, and only one of them can be installed in the M2 connector.

The NMA or NMV options are alternative, and only one of them can be installed in the M3 connector.

Up to three output options can be installed and operate simultaneously:

  • 4-20mA or 0-10V (only one)
  • RS232C, RS485, or ETH (only one)
  • 2 RELAYS, 4 RELAYS, or 4 OPTO (only one)
