GE Fanuc IC3500A452L208 Series 90-30 PLC Analog Output Module

In stock

Product Overview:
The GE Fanuc IC3500A452L208 is a 4-channel analog output module for the Series 90-30 PLC platform. This module provides 4 independent channels of 4-20mA current output (or 0-20mA, configurable), used to control final control elements such as control valves, variable frequency drives (VFDs), and damper actuators. It is a legacy but still widely deployed module in power plants, water treatment facilities, and industrial process control systems worldwide. The “L208” suffix indicates a specific firmware and hardware revision for long-term availability.

Technical Specifications:
Series: GE Fanuc Series 90-30
Number of Channels: 4 Analog Outputs
Output Signal: 4-20mA DC (default), 0-20mA DC (configurable via jumper)
Output Resolution: 12-bit DAC (4096 steps)
Load Impedance: 0 to 600Ω (at 24V DC supply)
Compliance Voltage: 24V DC (minimum supply voltage for output)
Update Rate: 10 ms per channel (typical)

Functional Features:
4 Independent Channels: Each channel can be programmed to output a different value simultaneously.
Current Output: 4-20mA is the industry standard for process control, providing live-zero fault detection (0mA = wire break).
Software Configurable: Output range (4-20mA or 0-20mA) set via on-module DIP switches or software.
Fault Detection: Supports open-loop detection (wire break) and over-range detection.
LED Indicators: Per-channel LEDs show output active status and fault conditions.
Legacy Support: Fully compatible with legacy 90-30 CPUs (IC3600, IC3400, etc.).

Performance Parameters:
Linearity: ±0.05% of Full Scale
Temperature Drift: < 50 ppm/°C
Settling Time: < 10 ms (to within 0.1% of final value)
MTBF: > 100,000 hours
Weight: Approximately 300 grams

Material Composition:
Housing: Zinc-plated steel chassis, powder-coated gray
PCB: FR-4 Glass Epoxy, 6-layer board with analog ground plane
DAC Chips: Precision current-output DACs (e.g., Analog Devices AD5421 or equivalent)
Terminals: Screw-type terminal blocks, tin-plated copper
Isolation: Optocouplers + isolated DC-DC converters per channel
