IC200ALG320 GE Fanuc 4-20 mA Current Output
Product Introduction
The GE Fanuc IC200ALG320 is a 4-point analog current output module from the VersaMax I/O family. This module provides four single-ended output channels, each generating a standard 4-20 mA signal. Specifically, it offers a resolution of 4 µA and a maximum update rate of 0.3 ms, ensuring precise and timely control. Therefore, the IC200ALG320 excels in applications requiring accurate analog signal generation, such as modulating valves, dampers, and variable frequency drives. Additionally, its built-in diagnostics and configurable fail-safe options enhance system reliability.
Technical Specifications
This section covers the essential technical parameters of the IC200ALG320. First, it features four analog current-sourcing outputs, each rated for 4-20 mA. The nominal output current averages 20.38 mA per channel, providing a robust signal for field devices. Furthermore, the analog resolution is 12 bits, translating to 4 µA per count, which allows fine-grained control. Meanwhile, the module achieves a typical accuracy of 0.3% of full scale, with a maximum of ±1%.
Moreover, the IC200ALG320 requires an external power supply for its output circuits. You can choose between an 18-30 VDC supply or a 9.6 to 15 VDC supply, offering flexibility for different system voltages. The module draws a maximum current of 240 mA from the external supply. Additionally, it consumes up to 50 mA from the backplane power. This dual-power design ensures stable operation even if one power source fluctuates.
For diagnostics, the module includes two LED indicators. One is the FLD PWR LED, which shows the presence of field-side power. The other is the OK LED, indicating that backplane power is available. Besides these visual cues, the IC200ALG320 offers diagnostic tools that detect loss of user-side power. This feature helps technicians quickly identify field wiring or supply issues. Furthermore, the module supports configurable output defaults. For instance, you can set it to hold the last state or default to 4 mA in case of a CPU stop or module fault. This flexibility prevents unintended actuator movements during system interruptions.
Mechanical and Environmental Parameters
The GE Fanuc IC200ALG320 operates reliably in industrial environments. Its temperature range spans from 0 to 60°C, and it withstands humidity levels of 5% to 95% non-condensing. The module's compact design fits standard VersaMax racks and terminal bases. Additionally, it features isolation between the user input and logic ground, rated at 250 VAC continuous and 1500 VAC for one minute. This isolation protects the control system from voltage spikes and noise.
Installation Guidelines
Installing the IC200ALG320 is a straightforward process. First, ensure that both the backplane and external power supplies are turned off. Then, mount the module onto a compatible VersaMax terminal base. Secure it by tightening the retaining screws. Next, connect your field wiring to the appropriate terminals on the base. For current outputs, use twisted-pair shielded cables to minimize electromagnetic interference. Additionally, verify that your external power supply matches the required voltage range (18-30 VDC or 9.6-15 VDC). After wiring, apply power and check the status LEDs. The OK LED should illuminate green, and the FLD PWR LED should confirm field power presence. Finally, configure the output default behavior via the host CPU or network interface unit.
