More Information

Overview Manuals Power States Fallback Jumper Voltage Mapping Applications

Features:

  • Four single-ended 0 to +10 V analog outputs
  • 12-bit conversion with a 0.3 ms maximum module update
  • Jumper selection for hold-last or 0 V interruption response
The General Electric IC200ALG321 part number denotes the four-channel unipolar-voltage member of the VersaMax analog output range.

Each controller word drives one field channel, while separate LEDs identify backplane availability and the external power needed by the output circuits.

The commissioning plan must match the load, supply range, carrier terminals and B13–B14 fallback jumper to the intended equipment behavior.

The General Electric IC200ALG321 Voltage Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Separating Rack and Field Supply

  • Backplane indication: The green OK lamp confirms that rack power reaches the module electronics.
  • Field indication: FLD PWR reports the user-side source that energizes the analog output circuits.
  • Supply choices: The field input can use either the standard +18 to +30 VDC span or the documented 12 V operating band.
  • Fault reporting: Loss of user-side power is sent to the controller as a module diagnostic.
  • State retention: The selected fallback remains effective only while external field power is uninterrupted.

Choosing the Interruption Output

  • Open B13–B14: Each channel retains its last commanded voltage by default.
  • Linked B13–B14: The four outputs change to 0 V after the documented interruption events.
  • Safe change: Both field and backplane sources are removed before the carrier jumper is moved.

Commands, Loads and Terminal Voltage

  • Word assignment: Four CPU or NIU words correspond in order to the four output terminals.
  • Count step: Accepted commands resolve in multiples of eight; intermediate values round downward.
  • Transfer equation: The manual relates commanded counts to the 10.25 V conversion span.
  • Load boundary: Field devices remain above the minimum resistance and below the maximum capacitance rating.

Fast Unipolar Voltage Control

  • Drive references: Four 0–10 V commands can set speed or torque references on compatible equipment.
  • Position demands: Actuator and valve interfaces can receive rapidly updated unipolar control levels.
  • Panel signals: Recorders, indicators or other high-impedance devices can follow individual controller values.
Description
Four single-ended 0 to +10 V outputs occupy one group in the General Electric IC200ALG321. The CPU or NIU writes four analog data words, and the module converts them at a maximum 0.3 ms update rate for fast voltage-command applications.

Field circuits on General Electric IC200ALG321 need a separate DC source even though the module electronics use backplane power. The manual permits either +18 to +30 VDC or a 9.6 to 15 VDC operating range; FLD PWR and OK indicators distinguish field-side supply from rack power.

A carrier jumper sets the interruption response of General Electric IC200ALG321. Leaving B13–B14 open holds the most recent command, while installing the link selects 0 V after backplane loss, communications interruption or a stopped PLC, provided field power remains present.

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.
Why do General Electric IC200ALG321 outputs keep their last command after the PLC stops?
General Electric IC200ALG321 holds the last state when no jumper is fitted across B13 and B14. This is the documented default response to a stopped PLC, communications interruption or backplane-power loss while field power remains available.
How can General Electric IC200ALG321 drive its channels to 0 V after communication is lost?
General Electric IC200ALG321 uses the B13–B14 carrier jumper to select the 0 V fallback. Remove both backplane and field power before changing the link, then confirm the behavior with the controller in a safe test state.
What does a dark FLD PWR indicator mean on General Electric IC200ALG321?
General Electric IC200ALG321 uses FLD PWR to show user-side power for the analog output circuits. Measure the external supply and return at A18 and A17 under load; the OK LED alone only confirms backplane power.
Which loads are suitable for General Electric IC200ALG321 voltage outputs?
General Electric IC200ALG321 is specified for at least 5 kΩ resistive loading and no more than 1.0 µF capacitive loading per the module data. A heavier or more capacitive load can keep the commanded voltage from settling correctly.
If General Electric IC200ALG321 receives a count that is not a multiple of eight, what happens?
General Electric IC200ALG321 rounds the value down to the nearest multiple of eight before conversion. Use the manual's count-to-voltage relationship when comparing the controller command with the measured field-terminal voltage.
Does General Electric IC200ALG321 require a 24 V field supply only?
General Electric IC200ALG321 accepts the documented +18 to +30 VDC range and also supports 9.6 to 15 VDC operation around a 12 V nominal source. Verify available load current and ripple inside the selected range.
