Cost-Efficient Precision with the GE IC695ALG708 Analog Output Module
When optimizing industrial automation budgets, every milliampere and volt counts. The GE IC695ALG708 PACSystem RX3i analog output module delivers eight configurable channels that directly impact your operational ROI by reducing signal waste and improving process control accuracy. This non-isolated module supports 0 to 20 mA and 4 to 20 mA current signals, as well as ±10 VDC and 0 to 10 VDC voltage signals, allowing you to match existing field devices without costly signal converters.

Industry Applications Driving Cost Savings
In chemical processing plants, the 0.15% full-scale accuracy at 25°C reduces product giveaway by minimizing dosing errors. For water treatment facilities, the 8 ms update rate enables tight PID loop control, lowering energy consumption on variable-frequency drive pumps. The 850 ohm maximum output load supports long cable runs without repeaters, cutting installation material costs.
Installation and Setup Guidance
Mount the module in any RX3i universal backplane slot. Connect an external +19.2 to +30 VDC power supply directly to the terminal block. Use compatible terminal blocks: Box-style (IC694TBB032), Extended Box-style (IC694TBB132), Spring-style (IC694TBS032), or Extended Spring-style (IC694TBS132). Configure channels for voltage or current output via Machine Edition Version 5.0 SP3 Logic Developer with CPU firmware 3.5 or later.
Maintenance and Reliability
The module's 7.25 W maximum dissipation ensures stable thermal performance within enclosures. Inspect terminal block connections annually for tightness. The built-in fault reporting and hold-last-state defaults minimize unplanned downtime, reducing maintenance labor costs.
Compatibility and Integration
The IC695ALG708 works with any RX3i CPU running firmware 3.5 or later. Data format supports IEEE 32-bit floating point or 16-bit integer in a 32-bit field, simplifying integration with existing control strategies. HART protocol is not supported.
Selection Guide and Purchasing Advice
For process loops requiring high resolution and fast settling, the IC695ALG708 offers a cost-effective solution. AutoDCSTech stocks this module with verified authenticity. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
Troubleshooting and Common Issues
If outputs do not respond, verify the external power supply is within +19.2 to +30 VDC and that the terminal block is fully seated. Check alarm settings for very low, low, high, and very high thresholds. Use the module fault reporting to isolate channel-specific issues without disconnecting wiring.
