ELS61-E REL2

RF Transceiver Modules And Modems Overview

The Telit Cinterion ELS61-E REL2 is a cellular RF transceiver module designed for M2M and IoT applications. It supports LTE Cat 1 with fallback to 2G (GSM/GPRS/EDGE) and 3G (UMTS/HSPA+). The module operates on frequencies including 800MHz, 900MHz, 1.8GHz, and 2.1GHz. It features an Intel XMM 7160 baseband processor with 30MB flash and 18MB RAM. Key electrical parameters include a supply voltage of 8V to 57V, transmit power up to 33dBm, and data rates up to 10.2Mbps. The unit is housed in a DIN rail mountable package.

• Integrates the Intel XMM 7160 modem for efficient processing and low power consumption.
• Provides multiple serial interfaces including RS232, SPI, I2C, and GPIO for flexible system integration.

RF Transceiver Modules And Modems Applications

• Machine-to-machine (M2M) communication systems
• Industrial Internet of Things (IoT) gateways
• Smart metering and utility automation
• Vehicle tracking and fleet management

RF Transceiver Modules And Modems Procurement Notes

Verify the specific revision level (REL.2) against current manufacturer documentation, as component revisions may impact pinout or firmware compatibility. Confirm that the 8V-57V wide input voltage range aligns with the target system power architecture. Ensure appropriate external antennas are selected, as the module does not include integrated antenna components. Check end-of-life status and last-time-buy dates if planning long-term production.

RF Transceiver Modules And Modems Selection Notes

Select this module when LTE Cat 1 performance is required alongside legacy 2G/3G network availability for broader geographic deployment. The wide operating temperature range (-40°C to 90°C) suits industrial environments. Consider the DIN rail form factor if space constraints favor this mounting style over standard PCB modules. Validate interface requirements such as RS232 and SPI against the host controller capabilities before finalizing the design.

RF Transceiver Modules And Modems Part Context

This component belongs to the Cinterion ELS61 series, which focuses on LTE Cat 1 solutions for the M2M market. The ELS61-E variant specifically targets global markets with multi-band support. The REL.2 suffix indicates a hardware revision within this product line, typically involving minor updates while maintaining functional compatibility with previous versions. It serves as a bridge between high-speed LTE and established 2G/3G infrastructures.

RF Transceiver Modules And Modems Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Telit Cinterion replacement guides or contact the manufacturer directly for validated alternatives due to the module's end-of-life status.
