【英文介绍】

Product description

The IC697ALG440 is a current extender module that can be paired with GE series 90-30 base converter modules. The complete analog subsystem includes basic converter and extender modules. The IC697ALG440 has 16 individually configurable current or voltage differential inputs. The base converter accepts bipolar or unipolar analog inputs up to 10 V at full scale. In addition, the base converter will accept 4 to 20 mA current loop signals. The IC697ALG440 provides individual user scaling for each input channel of the module. The entire subsystem accepts up to 120 inputs. Jumpers and DIP switches are not required, and fast update rates are normal for basic converters. The configuration is compatible with Windows or MS-DOS software features.

The input is converted to digital form for use by the CPU or a controller that accesses the analog input through the VME backplane. The input has transient and steady-state overvoltage protection. The percentage of AI referenced by the analog input is used for programmable controllers; However, up to 8k words of memory are currently available. Each input channel is set to use one word of %AI memory at 16 bits. Configuration is performed using MS-DOS or Windows software. Field wiring can be used with detachable terminal boards, and modules are mechanically keyed for proper replacement. The I/O baseline is configured by the user, as mentioned earlier, without the need for jumpers and/or DIP switches.

Technical specification

Voltage input range: -10 to +10 volts

Current input range: 4 to 20 mA

Calibration: Factory setting is 10 volts +/ -2mV

Number of inputs: 16 current inputs

Module type: Analog input expander module

Power: + 5 volts

The IC697ALG440 current input expander module belongs to the 90-70 series of programmable logic controllers produced by GE Fanuc. It has 16 current inputs with input currents ranging from 4 to 20 mA. The IC697ALG440 current input expander module must be used in conjunction with the base converter module and the voltage expander module to create an analog input subsystem for the programmable logic controller. Users can use these extender modules in any combination with basic converters to obtain a system with up to 120 input channels. It converts the digital form of the signal to the analog form and represents the converted data in the complement format of 2. Some of the extender module's features include status indicator leds, error detection tools, extender channel response detection, and module health diagnostics.

The IC697ALG440 current input expander module has an analog multiplexer for connecting the input to the analog-to-digital converter. The entire connection process is a switching circuit that connects one input at a time. Terminals 36 and 38 of the base converter module can be used to connect analog expansion signals. For the differential data bus, the user can select terminals 37 and 39 that act as serial communication ports. Be sure to consider polarity before connecting cables. If shielded, the shielding ground must be connected to terminal 35. However, masking is not mandatory, it is optional. The IC697ALG440 current input expander module must be located in the same rack as the expander module to which it is connected so that the modules are adjacent to each other.
