Siretta RJ12, RS232 4G, 2G Modem

This Siretta ZETA-NLP-LTEM (GL) modem provides serial-to-cellular connectivity for remote equipment using RJ12 and RS232 interfaces. It operates across cellular 4G and 2G networks and is suited to industrial environments where a Compact serial modem is required. The unit tolerates a broad supply range and functions across an extended temperature range for deployment in varied sites.

• 5V to 42V DC supply supports wide-voltage installations
• -40°C minimum operating temperature enables cold-site operation
• 85°C maximum operating temperature allows high-heat locations
• RJ12 and RS232 ports enable legacy serial device integration
• 90 g weight minimises load for constrained mounting

• Suitable for telemetry nodes with low-weight constraints
• Used for serial device connectivity in industrial cabinets
• Ideal for remote monitoring over 4G or fallback to 2G
• Can be used with DIN-rail setups requiring Compact modules
• Used for IoT endpoints needing wide-voltage tolerance

It provides RJ12 and RS232 connectors to link traditional serial devices.

It is rated to operate down to -40°C and up to 85°C.

The unit accepts a nominal supply range from 5V to 42V DC.
