Advanced Data Manager Comes In DIN-Rail Version

Endress+Hauser’s Memograph M RSG45 advanced data manager comes in a DIN-rail version. It is an intelligent remote device with extensive communication capabilities, viable for IIoT applications and use as an edge device for getting data to cloud-based servers.


The module can acquire data from up to 20 HART or universal analog input channels and 14 digital inputs. It has two analog outputs, up to 12 relay outputs, and makes its data available to IIoT systems and supports multiple communication interfaces and protocols. Interfaces and protocols include 4 mA to 20 mA HART, Modbus RTU/Modbus TCP/IP, PROFIBUS DP, PROFINET, EtherNet/IP, Ethernet TCP/IP, USB, RS-232C/RS485, and OPC.

Digi IX20 Secure LTE Router Available for Immediate Shipment from Digi-Key

The IX20 rugged, secure LTE router is a great choice for applications from basic connectivity to industrial-class and security solutions. Its high-performance architecture gives primary and backup WWAN over software selectable multi-carrier LTE.


With all these interfaces, the Memograph M also has an embedded web server that can be accessed by any web browser via the internet once proper security procedures are followed. All connections on the front of the device are designed as pluggable screw or spring terminal blocks, with reverse polarity protection in either case, making connections quick and easy. The spring terminals are unlocked with a slotted screwdriver.


The module provides tamper-proof data recording on 256 MB of internal memory compliant with various legal directives, a 32GB SD card, and a 32 GB USB drive. Integral software includes FDM Field Data Manager for visualization, analyzing, backup and reporting; audit trail software consistent with FDA21 CFR part 11; and Itherm TrustSens temperature sensor calibration. Application packages include mathematics, Telealarm, batch management, wastewater + RSB (rain spillway basin) and energy calculations.


The Memograph M can generate e-mail or SMS messages to alert users of alarm conditions or process events. Messages can be sent to several recipients simultaneously or automatically forwarded to a recipient/destination. Messages can be confirmed, relays controlled remotely, and current values queried by any web browser. For more information, peruse the Memograph M RSG45 datasheet.
