GE IC695ALG708

Product Introduction

The IC695ALG708 is an 8-channel non-isolated analog output module for PACSystems RX3i, designed to deliver precise voltage and current signals for industrial control applications. It is fully software-configurable via Proficy Machine Edition (no jumpers), with each channel independently settable to voltage (±10 V, 0–10 V) or current (0–20 mA, 4–20 mA) outputs. It offers 15.6–15.9 bits resolution (per range), 8 ms full-channel update rate, full autocalibration, and on-board diagnostics including high/low/high-high/low-low alarms, clamping, and over/underrange detection. The module uses detachable terminal boards (IC694TBB032/TBS032 or extended versions), supports hot-swap, and operates with RX3i CPUs (firmware 3.00+), providing flexible, high-precision control for actuators, valves, drives, and other field devices.

Function Features

  1. 8 Independent Configurable Channels: Each channel set to voltage or current outputs without hardware changes, adapting to mixed control needs.
  2. High-Speed Update Rate: 8 ms full-channel update ensures responsive control for dynamic processes.
  3. High-Resolution Conversion: 15.6–15.9 bits resolution delivers precise output for critical control loops.
  4. Software-Only Configuration: Proficy Machine Edition enables fast setup/reconfiguration, eliminating jumper errors.
  5. Full Autocalibration: Maintains long-term accuracy and reduces maintenance downtime.
  6. Advanced Diagnostics: Alarms, clamping, and over/underrange detection enable proactive fault handling.
  7. Hot-Swap Capability: Replace modules without chassis power-down to minimize production downtime.
  8. Configurable Biases & Clamping: Fine-tune outputs and protect loads with high/low clamping limits.
  9. Individual Channel LEDs: Visual status indicators allow quick troubleshooting of each output signal.
  10. Universal Terminal Compatibility: Works with box-style or spring-style terminal boards (standard/extended) for shielded wiring support.

Application Scenarios

  • Process Control: Drives control valves (4–20 mA), variable frequency drives (0–10 V), and positioners in oil/gas, chemical, and water treatment plants, using fast updates for PID loop responsiveness.
  • Manufacturing Automation: Controls motor speed (0–10 V), actuator position (4–20 mA), and heater power (±10 V) in automotive assembly, semiconductor fabrication, and packaging lines, leveraging channel flexibility for mixed actuators.
  • Power Generation: Adjusts transformer taps (4–20 mA), generator voltage regulators (0–10 V), and grid controls in utilities, using high resolution for precise power management.
  • Marine & Offshore: Complies with marine certifications, controls shipboard valve actuators (4–20 mA), lighting dimmers (0–10 V), and pump speeds in Zone 2/ATEX C1D2 environments.
  • Building & Infrastructure: Manages HVAC dampers (4–20 mA), variable air volume (VAV) units (0–10 V), and energy meters (±10 V) in smart buildings, using software configuration for flexible system design.
  • Food & Beverage: Controls oven temperature (4–20 mA), mixing tank agitator speed (0–10 V), and filling flow rates (0–20 mA) with autocalibration for consistent quality control.
