GE IC693ALG390..IC693MDL930 2‑Channel Bipolar Voltage Analog Output Module

Description

Basic Hardware Information

‑ Output channels: 2 independent single‑ended voltage outputs ‑ Output range:‑10 VDC ~ +10 VDC bipolar ‑ DAC resolution: 13‑bit (12‑bit + sign); step size 2.5 mV ‑ Update time: 5 ms typical for both channels ‑ Accuracy: ±5 mV @25 ℃; ±15 mV over full operating temperature range ‑ Minimum load resistance: 2 kΩ per channel; max load capacitance 2000 pF ‑ Galvanic isolation: 1500 V RMS 1‑minute dielectric withstand between field circuit and PLC logic backplane; no channel‑to‑channel isolation ‑ Power consumption: 40 mA @5 VDC (backplane logic); 100 mA @24 VDC external user power ‑ Termination: Detachable screw terminal block ‑ Mechanical: Single‑slot Series 90‑30 form‑factor; baseplate mounting; non‑hot‑swappable, rack power must be removed during module replacement ‑ Status indicators: Front‑panel OK LED for module health status ‑ Operating ambient temperature: 0 ℃ ~ +60 ℃; storage temperature ‑40 ℃ ~ +85 ℃; relative humidity 5‑95 % non‑condensing ‑ Handling note: ESD‑sensitive hardware; anti‑static wrist strap required during maintenance ‑ Compatibility: Works with Series 90‑30 CPU family; cannot be used in Series 90‑70 / VersaMax racks.

Core Functions & Features

1. Converts digital values stored in PLC %AQ registers into‑10 ~ +10 VDC analog control signals, regulating control valves, actuator positioners and variable‑speed drive set‑points.
2. Bipolar output supports positive‑negative control requirements for forward/reverse adjustment scenarios.
3. Channel‑level short‑circuit protection; output shuts down under short‑circuit condition to avoid internal driver damage.
4. Detachable terminal block keeps field wiring intact while swapping module, shortens maintenance downtime.
5. Revision‑F /‑G units are direct drop‑in replacements for older IC693ALG390 hardware; no wiring or software modification required.

On‑site Installation & Commissioning Notes

1. Power‑off complete Series 90‑30 rack before installing or removing IC693ALG390; apply anti‑static protection. Fully seat module into baseplate slot until locking tab clicks firmly.
2. Use shielded twisted‑pair cables for analog field wiring; separate analog signal cables from high‑voltage AC and heavy‑power discrete wiring to reduce EMI interference; single‑point shield grounding is recommended. Torque terminal‑block screws to specified torque value.
3. Provide stable 24 VDC external user power supply to module terminals; verify power polarity to prevent driver damage.
4. Complete hardware slot configuration within PLC programming software, assign slot module‑type as IC693ALG390, download configuration to CPU.
5. After commissioning, verify steady‑on OK‑LED status. Perform signal output test for each channel, validate output voltage range and response performance.
6. Replacement note: Current‑output analog modules cannot serve as direct substitute. After replacement, confirm external 24 VDC user‑supply and execute full‑point analog‑channel test.
