Patton SmartNode SN4141E/2JS2V/DC Industrial & Military-Grade Rugged VoIP Gateway | 2 Analog Ports

SKU: 4475 Category:





Cloud Enabled The ruggedized SN4141E/2JS2V/DC Industrial VoIP Gateway series is ideal for delivering Voice-over-IP telephony in outdoor or environmentally exposed environments where heating and cooling cannot be controlled. The SN4141E/2JS2V/DC is a member of the SN4140E product series. The unit can be vehicle-mounted and is suitable for military applications. Offering 2 analog (POTS) FXS  interfaces, Patton’s industrial VoIP gateway facilitates IP-based voice delivery for such applications as industrial automation, military communications, railways, public transportation, public and private outdoor phones—includingemergency phones in parking lots, along roadways and railways and within underground tunnels.

The SN4140E gateway provides interconnection and conversion between modern IP-based Voice networks using Session Initiation Protocol (SIP) and traditional analog phones, analog PBX equipment or PSTN lines. All-IP means voice terminals everywhere need to be adapted to VoIP.

Housed in a hardened metal enclosure, the SN4140E device is designed to withstand shock (IEC 60068-2-27), vibration (IEC 60068-2-6), extreme temperatures (-40 to +70C), up to 85% humidity (conformal coating option protects up to 100%), condensation, and frost. DIN-rail mounting and shelf mounting are supported. 12-48 VDC terminal block power input is standard, while an AC-to-DC adapter, with a screw-down plug fastener, is available as an accessory.

Protection against power spike and surge is built in according to MIL STD 1275.
