• The design of the device with regard to its future expansion allows the customer easy additional additions to the modules and functions of the device. The ELCORplus device for zone 2 can be equipped with up to two serial interfaces RS232/RS485, internal modem (variants for 2G/4G/NB networks), external modem, up to 12 digital inputs, analog inputs, and outputs 4 - 20 mA, interfaces for NAMUR encoder connection or SCR+ and last but not least, a total of up to 6 digital pressure and temperature transducers can be connected to the device.

    Thanks to the rich hardware equipment that comes from the ELCORplus device, robust software with telemetry functions, the ELCORplus for zone 2 becomes one of the most equipped and powerful converters on the market.

    The extended measuring ranges of the pressure transmitter make it easier for the customer to order a converter.

    The device is also available in a version capable of measuring and operating at temperatures from -40 °C.

    The wireless connectivity of the ELCORplus converter allows the connection of various modems. Internal modems are available for 2G, 4G, and NB (NarrowBand) networks and can be used in ZONE 2 potentially explosive atmospheres.

    All communication interfaces of the device are independent.

    The device includes a data logger with a large 16MB memory, which allows you to store measured data at hourly intervals for more than 10 years.

    The housing of the device was designed for operation in demanding conditions of the outdoor environment with certification of the degree of protection IP66.
