Multifunction Ind. 10-70VDC/21-53VAC, BT+MQTT, ETH

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

• Process Input: Voltage (V), Current (mA)
• Load Cell Input: Millivolts (mV)
• Pt100 Input
• Thermocouple Inlet: 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 input variables
• Remote retention functionality
• Reading and memorizing maximum and minimum values (peak/valley)
• Tare and reset functions
• Extensive programmable logic functions

Exit Options

Several additional output cards can be installed to enhance the system:

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

All output options are opto-isolated from the input signal and power supply.

Control Options

The MICRA-M MAX supports several control output options:

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

Communication and Configuration

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

• Web Server: Allows initial configuration with login and provides instant readings of measured variables.
• Bluetooth: After downloading the Ditel Connect app, the instrument can be configured using a smartphone.
• MQTT Protocol: Enables communication with an MQTT server.
• REST API: Facilitates communication and data exchange between different systems.

• Quick Start Guide for the Panel Indicator
• MICRA-M MAX digital panel indicator
• Panel mounting accessories (sealing gasket and fixing clips)
• Wiring connection accessories (plug-in terminal block connectors)
• Wiring label attached to the MICRA-M MAX housing
• Four sets of labels with engineering units

The instrument features software that allows configuration via its keypad, providing access to separate programming menus for input, display, and logic functions. If additional options are installed (communication outputs, analog output, and relay output), these are automatically recognized by the instrument and activate their own programming software.
Programming can also be done via a PC using the built-in web server and configuration API, or via Bluetooth on a smartphone using the DITEL Connect APP, which can be downloaded from our portal: micramax.ditel.es .
The complete or selective locking of programmed parameters can be managed via the web server or the local keypad. The instrument is shipped from the factory with the programming unlocked, allowing the operator full access to all programming levels.

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

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

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

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

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