IC697ALG440 GE current expander module

IC697ALG440 is a current expander module, which can be paired with a GE Series 90-30 base

converter module. The completed analog subsystem includes the base converter and expander modules.

IC697ALG440 has 16 individually configurable differential inputs for current or voltage. The base converter

accepts bipolar or unipolar analog inputs of up to 10 volts on the full scale. In addition, the base converter will

accept 4 to 20 milliamp current loop signals.

IC697ALG440

IC697ALG440 offers individual user scaling for each of the module’s

input channels. The complete subsystem accepts a maximum of 120 inputs. Jumpers and DIP switches are not

required, and a fast update rate is normal for the base converter. Configuration is compatible with Windows or MS-DOS software functions.

Inputs are converted to digital form for CPU use or for controllers accessing analog inputs via the VME backplane.

Inputs are protected against transient and steady state overvoltage conditions. Percent AI references via the analog

inputs are utilized in the programmable controller; however, a maximum of 8k words of memory is presently available.

Each input channel is set to use one word of %AI memory at 16 bits. Configuration is executed through the use of MS-DOS

or Windows software. Field wiring is available to make use of a removable terminal board, and the module is mechanically

keyed to correct replacement. I/O references are configured by the user, which as previously mentioned, eliminates the need for jumpers and/or DIP switches.
