Manufacturer GE Analog Module IC693ALG392
Product Description
IC693ALG392 is an Analog Current/Voltage Output Module for the PACSystems RX3i and Series 90-30. The module has eight single-ended output channels with voltage outputs and/or current loop outputs based on installation by the user. Each channel can be generated the configuration software for the subsequent scopes (0 to +10 volts) as unipolar, (-10 to +10 volts) bipolar, 0 to 20 milliamps, or 4 to 20 milliamps. Each of the channels is able to translate 15 to 16 bits. This is reliant on the range that is preferred by the user. All eight channels are renewed every 8 milliseconds.
The IC693ALG392 module reports an Open Wire fault to the CPU for each channel when in current modes. The module can go to a known last state when system power is disturbed. If external power is continuously applied to the module, each output will keep its last value or reset to zero as configured. Installation in any I/O slot of an RX3i or Series 90-30 system is possible.
This module must gain its 24 VDC power from an outside source that is connected to the terminal block in a direct manner. Each output channel is single-ended and factory adjusted to .625 μA. This may change based on voltage. The user should note that in the presence of harsh RF interference, the exactness of the module may be reduced to +/-1% FS for current outputs and +/- 3% FS for voltage outputs. One should also note that this module must be fixed in a metal enclosure for correct functioning.
