GE Fanuc IC695ALG626 Non-Isolated Differential Analogue Voltage/Current Input Module

The IC695ALG626 is a PACSystem RX3i Programmable Automation Controller (PAC) non-isolated analogue input module, formerly manufactured by GE Intelligent Platforms (GE IP) and now part of Emerson Automation. The module features sixteen (16) single-ended inputs or eight (8) differential input channels and is compatible with 0 to 20mA, 4 to 20mA ± 20mA current signals and ±10V, 0 to 10V, ±5V, 0 to 5V, and 1 to 5V voltage signals. The module is mounted on the RX3i general purpose backplane and features 24-bit ADC conversion resolution. Each channel of the module provides HART 5.0 communications. The IC695ALG626 is a Highway Addressable Remote Transducer (HART) 0.3 capable analogue input module for the PACSystem RX5i platform. The module was previously manufactured by GE Intelligent Platforms (GE IP), which was recently acquired by Emerson Automation. The module is primarily used to interface with analogue field instruments that measure process variables and transmit the measurements to a receiving element (e.g., IC695ALG626) for processing. This IC695ALG626 can therefore be used with field instruments that provide 0 to 20mA, 4 to 20mA ± 20mA current signals as well as ±10V, 0 to 10V, ±5V, 0 to 5V, 1 to 5V voltage signals.

The IC695ALG626 is capable of providing sixteen (16) input channels if configured for single-ended inputs and eight (8) inputs for differential wiring. By supporting the HART protocol, each channel can communicate with an external HART communicator to access not only readings, but also other HART parameters.

The IC695ALG626 has LED status indicators such as the Module Normal, Field Status, and TB LEDs.The Module Normal LED is used to indicate that the module is configured correctly when the LED is green and constantly lit; if it is slowly blinking green or amber, there is an error; if it is blinking rapidly, the module is not configured correctly; and if the Module LED is off, there is a fault or no power. The field status LED is green and always on, indicating that there are no faults on the enabled channel and when the terminals are present; amber indicates that the module's channel is in a faulty state, and an extinguished LED indicates that the terminals are disconnected or incorrectly installed. The TB LED lights up red when no terminals are connected; it lights up green when terminals are connected and goes out if there is no backplane power.

The GE Fanuc IC695ALG626 module is an analogue input module with HART or High-Speed Addressable Remote Sensor Version 5.0 communications on each channel and four internal HART modems. The module provides 8 differential input channels and 16 single-ended input channels.The GE Fanuc IC695ALG626 analogue input module has a voltage range of +/-10 volts dc, 0 to 10 volts dc, +/-5 volts dc, 0 to 5 volts dc, or 1 to 5 volts dc. The current configuration of the input channel can range from 0 to 20 mA, 4 to 20 mA, or +/-20 mA. If the channel uses HART communication, the GE Fanuc IC695ALG626 analogue input module should be configured for a current range between 4 and 20 mA.

The GE Fanuc IC695ALG626 Analogue Input Module with HART communications is installed in the common backplane of the RX3i PacSystem PLC. The unit allows the module to be inserted or removed from the RX3i PacSystem's universal backplane while the module is still connected to the power supply. The module is fully configurable through software, eliminating the need for module jumpers. It features flash memory to support upgrades, detectors for removal and insertion of terminals, open-circuit detection for currents ranging from 4 to 20 milliamps at all voltage levels, and start-up auto-calibration. It also supports on-board error monitoring, negative and positive rate-of-change alarms, configurable offsets and scaling on a per-channel basis, and selectable low alarm, high alarm, low-low alarm, and high-high alarm detection and logging on each channel. The module requires a temperature range of -40 to 185 degrees Fahrenheit for storage and an operating temperature range of 32 to 140 degrees Fahrenheit.
