AB 1794-IF8IH FLEX I/O Isolated Input HART Analog Module

Isolation and power supply: Isolation voltage is 120V (continuous), basic insulation type, tested by 1000V AC for 60s, including isolation between user power supply and system, channel and system, and channel and channel.Flexbus current is 80mA @ 5V DC, used to supply power to the Flexbus interface of the module; maximum power consumption is 4.8W at 31.2V DC, and maximum heat dissipation is 16.4BTU. Maximum power consumption is 4.8W at 31.2V DC and maximum thermal dissipation is 16.4BTU/hr; external power supply requirements are 24V DC (19.2-31.2V DC with 5% AC ripple) and supply current is 190mA at 24V DC.

Physical Parameters

Dimensions: Measures approximately 94 x 94 x 66mm (3.7 x 3.7 x 2.6in.) when mounted for easy installation in a facility.

Indicator Lights: Equipped with 1 red/green power/status indicator light, which reflects the working status of the module through different colours and blinking status, e.g. blinking green indicates that the module's configuration word is zero, the power is off, or it is in the configuration mode, while red indicates that it has not passed the initial hardware test.

Wire-related: Wire size is determined by the installed terminal block, shielded wires are required, wiring category is divided into signal port category 2, power port category 3, which can be used for planning wire routing, and the grounding conductor should be equal to or greater than the phase conductor.
