        Overview Manuals Bipolar Scaling Load Interface Three-Point Test Diagnostic Path

        Features:

        • Two independent bipolar channels deliver -10 to +10 VDC commands.
        • Twelve-bit resolution represents both sign and magnitude for bidirectional control.
        • External-power and terminal diagnostics shorten analog fault isolation.
        Bipolar output is useful where the sign of the command selects direction. Hardware polarity, PLC scaling, and the receiving device interpretation must all agree before the controlled equipment is enabled.

        The low output impedance supports a stable voltage reference into a compatible load, while the published current limit constrains what the module can drive directly.

        A complete loop test includes negative full scale, zero, and positive full scale. This exposes sign errors and offsets that a single positive test cannot reveal.

        Relating PLC data to direction and magnitude

        • Negative command: One side of the code range represents reverse or negative demand.
        • Zero point: Midscale behavior should correspond to the intended neutral condition.
        • Positive command: The opposite side produces positive output toward full scale.
        • Receiver agreement: Make field-device scaling match the PLC sign convention.

        Conditions for a valid ±10 V reference

        • Impedance: Use a receiving load compatible with the documented output capability.
        • Current limit: Do not use the analog output as a power source for the field device.
        • Polarity: Preserve output and return connections during replacement.
        • Shielding: Maintain the intended cable shield and grounding arrangement.

        Proving direction before process release

        • Negative test: Apply a limited reverse command and verify measured polarity.
        • Zero test: Check the receiver for offset at the neutral command.
        • Positive test: Confirm magnitude and direction at a safe forward value.
        • Record results: Retain command, measured voltage, and receiver response.

        Tracing a missing or fixed output

        • External supply: Verify 24 VDC at the module.
        • Terminal block: Reseat the removable assembly and inspect contacts.
        • PLC word: Confirm the correct output reference changes.
        • Field receiver: Measure at the device to locate an open or wiring reversal.
        Description
        General Electric IC655ALG567 is a Series Five 2-Channel Bipolar Analog Output Module that creates independent -10 to +10 VDC command signals. Its bipolar range is intended for compatible references that express both direction and magnitude around a defined zero point.

        A signed 12-bit value controls each output of IC655ALG567, which can source or sink current into the documented load. PLC scaling, terminal polarity, and receiver direction must agree because reversed conductors or an inverted scale can make an otherwise valid value drive the mechanism the wrong way.

        The analog side of IC655ALG567 is optically isolated from the rack logic and relies on an external 24 VDC supply. Diagnostic reporting for loss of that supply or removal of the terminal assembly helps separate hardware availability from a problem in the command data or receiving equipment.

        Commissioning IC655ALG567 requires checks at negative, zero, and positive reference points rather than a full-scale reading alone. Receiver impedance, shield and return routing, and small zero offset become especially important when the output is used as a positioning or speed reference.

        Technical notes
        IC655ALG567 commissioning should verify negative, zero, and positive outputs at the receiver, along with polarity, load impedance, and external 24 VDC.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why does IC655ALG567 drive in the opposite direction after replacement?
        When checking the IC655ALG567 application, check field polarity, the PLC sign convention, and receiver configuration; the module can produce a correct bipolar voltage while the connected device interprets its sign differently.
        What should be measured when IC655ALG567 will not pass through zero cleanly?
        At the IC655ALG567 load connection, test the output at negative, zero, and positive commands, compare the offset at the module and receiver, and inspect grounding and shield paths before changing software bias.
        Can IC655ALG567 drive a low-resistance load directly?
        While tracing an IC655ALG567 fault, only within its documented voltage, current, and load limits; verify receiver impedance rather than assuming every ±10 V input is suitable.
        Why can one IC655ALG567 channel work while the second remains fixed?
        During IC655ALG567 functional checks, the channels are independent, so compare the assigned PLC word, field terminals, output data, and receiving device for the affected channel while confirming common external power.
        What does an IC655ALG567 diagnostic alarm suggest first?
        When reviewing the IC655ALG567 configuration, check the external 24 VDC source and terminal-block seating, because loss of either can stop analog delivery even when Series Five logic continues to scan.
        How should a bidirectional actuator be made safe for IC655ALG567 testing?
        At the IC655ALG567 communication pathdisable process authority or uncouple motion as required, apply limited test commands in both directions, and verify sign at the receiver before returning automatic control.
        What can cause IC655ALG567 output to appear unstable near zero?
        When working with IC655ALG567, investigate shield termination, unintended ground loops, receiver noise, loose terminals, and scaling resolution before attributing the variation to the converter.
