        Overview Manuals Installation & Integration RTD Support Measurement Diagnostics

        Features:

        • Excites and measures four independent RTD circuits
        • Allows a different supported sensor definition on each active channel
        • Provides optional status words and host-controlled fault clearing
        IC670ALG620 can place four analog input words and up to 32 optional diagnostic bits in the BIU data tables; four output bits are available for clearing stored channel faults.

        A channel may report resistance or temperature, and its selected RTD curve can be adjusted in tenths of an ohm when the installed element differs from the nominal definition.

        Inactive channels return zero and are not scanned. For active points, confirm lead resistance, wiring arrangement, measurement units, and 50 Hz or 60 Hz acquisition selection.

        Official documentation and sensor-matching review are available for the General Electric IC670ALG620 4-Channel RTD Analog Input Module.
        General Electric IC670ALG620 4-Channel RTD Analog Input Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Station Integration

        • Bus Interface: IC670ALG620 exchanges input words and optional status data through a compatible Field Control BIU.
        • BIU Revision: The station requires Bus Interface Unit revision 2.0 or later for this intelligent input module.
        • Channel Setup: Each sensor channel is enabled and assigned its RTD type before field measurements are used.
        • Lead Wiring: Three-wire and four-wire connections must follow the channel terminals and supported lead-resistance limits.

        Sensor and Lead Options:

        • Independent inputs: Four channels accept individual RTD sensor circuits.
        • Lead arrangement: Each point can use the documented three-wire or four-wire connection.
        • Sensor families: Supported definitions include platinum, copper, nickel, and nickel/iron elements.
        • Resistance selection: Direct measurement ranges of 0–500 Ω and 0–3000 Ω are available.

        Reported Data and Scan Timing:

        • Digital format: Input conversion uses 15 bits plus sign for the measured value.
        • Selectable units: The BIU can receive 0.1 Ω, 0.1°C, or 0.1°F values for each configured channel.
        • Point scan: Approximate scan time is 210 ms at 60 Hz or 230 ms at 50 Hz.
        • Noise rejection: Normal-mode rejection is specified at 60 dB for 50 Hz and 60 Hz environments.

        Sensor Circuit Supervision:

        • Continuity faults: Dedicated status bits distinguish an open RTD from a shorted input.
        • Wiring check: Each channel can flag a wiring error separately from range alarms.
        • Process limits: High, low, underrange, and overrange conditions are reported without changing the measured value.
        • Host reset: One optional output bit per RTD clears stored diagnostic bits after the circuit has been corrected.
        Description
        General Electric IC670ALG620 is a four-channel RTD analog input module for Field Control distributed I/O stations. Each isolated channel receives one supported resistance-temperature sensor circuit.

        Excitation current from IC670ALG620 supports three-wire or four-wire platinum, copper, nickel, and nickel/iron RTDs, with the sensor definition selected independently for each channel.

        Host data from IC670ALG620 can be represented in tenths of an ohm, tenths of a degree Celsius, or tenths of a degree Fahrenheit. Channel settings include resistance adjustments and configurable alarm limits.

        Diagnostic data from IC670ALG620 distinguishes open sensors, shorted inputs, wiring errors, underrange, overrange, and limit alarms. The module operates through a compatible Field Control Bus Interface Unit.

        VIEW ALL FAQS
        Which RTD materials can be connected to IC670ALG620?
        IC670ALG620 supports documented platinum, copper, nickel, and nickel/iron RTD types in three-wire or four-wire configurations.
        Can IC670ALG620 mix different RTD types on its four channels?
        Yes. IC670ALG620 lets each active channel use a different supported RTD definition and resistance adjustment.
        What measurement units can IC670ALG620 return?
        IC670ALG620 can return values in 0.1 Ω, 0.1°C, or 0.1°F units according to channel configuration.
        Does IC670ALG620 need an external excitation supply?
        No. IC670ALG620 provides the RTD excitation current internally and automatically matches it to the configured sensor type.
        How quickly does IC670ALG620 scan an RTD point?
        IC670ALG620 scans a point in approximately 210 ms with the 60 Hz setting or 230 ms with the 50 Hz setting.
        Which sensor faults are diagnosed by IC670ALG620?
        IC670ALG620 reports open RTD, input short, wiring error, underrange, overrange, and per-channel high or low alarm conditions.
        What must be checked before replacing IC670ALG620?
        Before replacing IC670ALG620, verify the exact RTD type, three-wire or four-wire termination, lead resistance, units, alarm limits, terminal block, and BIU revision.
