AB 1794-IE8H FLEX I/O 8 Input HART Analog Module

Isolation and power supply: Isolation voltage is 50V (continuous), basic insulation type, tested at 850V DC for 1s to ensure electrical safety Flexbus current is 80 mA at 5V DC and 190 mA at 24V DC; power supply requirements are 24V DC (voltage range 19.2-31.2V DC with 5% AC ripple), powered by a 1794-PS13 power supply at 31.5V DC. The PS13 power supply has a maximum power consumption of 3.9W at 31.2V DC and a maximum thermal dissipation of 13.5BTU/hr.

Physical Parameters

Dimensions and Weight: Measures approximately 46.0 x 94.0 x 75.0mm (1.8 x 3.7 x 2.95in.) when mounted and weighs approximately 200g (7.05oz) for ease of installation in equipment layouts.

Indicator Lights: Equipped with 8 red fault indicator lights, 8 yellow channel indicator lights and 1 green power indicator light, which indicates the working condition of the module through different colours and statuses for easy monitoring.

Wire-related: Wire size is determined by the installed terminal block, shielded wires are used for signal ports, and the wiring category is Class 2 for both signal and power ports, which can be used for planning wire routing.

Environmental parameters

Temperature range: Operating temperature - 20 - 55°C (-4 - 131°F), storage temperature - 40 - 85°C (-40 - 185°F), can be adapted to a certain range of temperature changes .

Humidity and others: Relative humidity requirements of 5 - 95% non-condensing; able to withstand a certain degree of vibration and shock, vibration conditions for the 2g @ 10 - 500Hz, operating shock and non-operating shock of 15g; in terms of electromagnetic compatibility, in line with the relevant standards, such as CISPR 11 in the Group 1, Class A standards (with a suitable enclosure), the Electrostatic Discharge (ESD), radiation radio frequency (RF), electrical rapidity of （It is immune to electrostatic discharge (ESD), radiated radio frequency (RF), electrical fast transient pulse bursts (EFT/B), surge transients and conducted RF.
