Module de sortie analogique GE Fanuc IC694ALG392 PACSystems RX3i et série 90-30

Description

The IC694ALG392 is an 8-channel analog output module designed for use with PACSystems RX3i and Series 90-30 PLC systems. It provides up to eight single-ended output channels with current loop outputs and/or voltage outputs. Each output channel can be independently set up using the configuration software for any of these ranges: 0 to +10 V (unipolar), -10 to +10 V (bipolar), 0 to 20 mA, and 4 to 20 mA.

Each channel of the IC694ALG392 is capable of converting 15 to 16 bits (depending on the range selected) of binary data to an analog output. All eight channels are updated approximately every 8 milliseconds, determined by the I/O scan time and application. In current modes, the module reports an Open Wire fault to the CPU for each channel. As long as external power is applied to the module, each output will maintain its last value or reset to zero, as configured, when system power is interrupted. This module can be installed in any I/O slot of an RX3i or Series 90-30 system.

Features

• 1 to 8 selectable single-ended analog output channels.
• Flexible software configuration for multiple current and voltage ranges.
• High-resolution conversion (15 to 16 bits depending on the selected range).
• Fast update rate of approximately 8 milliseconds for all eight channels.
• Channel-specific Open Wire fault reporting to the CPU in current loop modes.
• Configurable default behavior (maintain last value or reset to zero) upon system power interruption.
• Dual LED diagnostics driven by the backplane power bus to indicate module state and user supply status.

Applications

• Proportional control valves and industrial actuators.
• Speed reference signaling for variable frequency drives (VFD).
• Dynamic chart recorders and process data logging equipment.
• Interface connections to remote instrumentation panels.
• Industrial automated processes in standard and Class I, Division 2 environments.

Note: Each channel can be configured to operate as a voltage output or a current output - not both simultaneously.

Module Status Indicators

Installation Guidelines

• External Power Connection: The module must receive its 24 VDC power from an external source connected directly to Terminal 1 and Terminal 19 of the module's terminal block.
• Thermal Derating: For maximum performance and module life, the module should be operated at maximum load resistance to offload heat. Module thermal deratings depend on the voltage level and the mix of current and voltage outputs. For example, at VUSER = 30 V with 2 voltage channels (2 K Ohm loads) and 3 current channels (shorted loads), the maximum operating temperature is approximately 52.5 degC.
• RF Susceptibility and Shielding: In order to meet the specified RF susceptibility levels, the system must be mounted in a metal enclosure when this module is present. In the presence of severe RF interference, accuracy may be degraded to +/-1% full scale (FS) for current outputs and +/-3% FS for voltage outputs.
• Cable Grounding: Wire the cable shield ground directly to Terminal 20 (Frame Ground).
• Hazardous Area Precautions: Suitable for use in Class I, Division 2, Groups A, B, C, and D or non-hazardous locations only.
• Explosion Hazard Warnings: Turn off power before replacing or wiring modules when in hazardous locations. Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous. Component substitution may impair suitability for Class I, Division 

System Compatibility Requirements

• Series 90-30 CPU Firmware: For Series 90-30 PLC CPU firmware versions 3.3 to 4.6, the module must be configured for 16 %I inputs, otherwise a Loss of Module Fault will occur. CPU firmware must be version 5.0 or later to configure the module for 8 %I inputs.
• Hand-Held Programmer: Only Series 90-30 modules version C or earlier support the Series 90-30 Hand-held Programmer. Series 90-30 modules version BD or later and all versions of RX3i modules cannot be used with a Hand-held Programmer.

Compliance and Certifications

• Class I, Division 2, Groups A, B, C, D Hazardous Locations
