heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets. Its operating
temperature ranging from -40 to 75 degrees C allows the Industrial Modbus Gateway to be placed in almost any
difficult environment.
The Industrial Modbus Gateway is equipped with a compact IP40-rated metal case that allows wall mounting for
efficient use of cabinet space. The Industrial Modbus Gateway also provides an integrated power supply source
with wide-ranging voltages (9 to 48V DC) ideally suitable for worldwide operation with high availability
applications.
