Quick Summary
CMC III LTE Unit provides alarm forwarding via SMS for remote monitoring in industrial automation. When a plant loses its network infrastructure, critical alerts can be missed, increasing risk and response times. While CE conformity, IP-rated enclosures, and SIL compatibility are common expectations in industrial control hardware, this unit is designed to maintain alerting through mobile networks and robust handling in harsh environments. The solution integrates with the CMC Processing Unit and requires a SIM card, delivering reliable SMS alarms even where wired connectivity is unavailable. By simplifying remote monitoring and reducing response times, it supports uptime optimization and safer, compliant operation across plant floors.

FAQs
Begin by mounting the CMC III LTE Unit inside the enclosure, securing the RJ12 connections to existing devices, and attaching the aerial. Insert a standard SIM card provided by the customer. Then connect to the CMC Processing Unit using the 2 x RJ12 serial interfaces. Confirm network bands are supported by your SIM and test SMS alert flow to ensure reliable operation.
The unit supports LTE (4G), UMTS (3G), and GSM (2G) networks with an automatic changeover function. If one network path fails or is unavailable, the device automatically switches to an alternate available path to ensure alarm messages are delivered via SMS without manual intervention.
Industries with distributed or remote equipment—such as manufacturing lines, water treatment, and energy infrastructure—benefit from guaranteed SMS alerts when wired networks are unreliable. Use cases include alert forwarding for critical process controls, remote monitoring of isolated assets, and rapid incident response without on-site IT dependencies.
The product data includes classifications such as ETIM 9 and ECLASS 8.0, which aid cataloging and interoperability. For regulatory certifications like CE or IP ratings, consult official Rittal documentation or contact the supplier to confirm current certifications applicable to your region and application.
The LTE Unit reduces downtime by preserving alert delivery even during network outages, lowering incident response times. Maintenance involves periodic SIM management, battery-free operation, and routine verification of RJ12 connections and antenna alignment. Over time, this translates to lower OPEX through fewer failed alarms and improved asset availability.
