Essential details：1797-OE8 FLEX Ex I/O Module
The Flex Ex 1797-OE8 is one of the best analog output modules on the market that is manufactured by Allen-Bradley. The device comprises 8 channels which are non-isolated and single-ended. The isolation conversion of the 1797-OE8 is from Galvanic to DIN EN60079-11. The 1797-OE8 requires a NEMA certified IP20 enclosure for safety purposes. The device requires 12 AWG stranded cables to connect to a power source. The indicator panel of the 1797-OE8 has 8 fault indicators and 1 power indicator that are red and green, respectively. It has 4 key switch positions. The voltage rating of the 1797-OE8 at 22 MA is more than 11 Volts. The Uo and Ui of the 1797-OE8 are less than or equal to 21 Volts and 9.5 Volts DC respectively.
The current rating of the 1797-OE8 ranges between 0 and 22 MA. The Io and Ii of the 1797-OE8 are more than or equal to 100 MA and 1 Amp, respectively. The operational power consumption of the 1797-OE8 is 6.3 Watts. The temperature rating of the 1797-OE8 ranges between -4 and 158 degrees Fahrenheit. The device is temperature-sensitive during operations and needs a non-condensing environment with relative humidity ranging between 5 and 95%. The 1797-OE8 generates 2G vibrations at 10 to 500 Hertz. The shock generation of the 1797-OE8 is 15G. The response time between the module and adapter of the 1797-OE8 on average fluctuates from 200 to 1600 Microseconds. The 1797-OE8 has panel type mounting and comes with DIN rails when shipped. The length, width, and height of the 1797-OE8 without packaging are 3.7 x 2.95 x 1.8 inches, respectively.
