Description

GE  IC693ALG221  Series 90-30 series analog current input module

Number of channels: 4 single-ended input channels.
Input type: Analog current input.
Input range: Default 4-20mA, adjustable to 0-20mA via jumper.
Resolution: 12-bit. When the input signal is 4-20mA, the resolution is 4µA (1LSB = 4µA). When the input signal is 0-20mA, the resolution is 5µA (1LSB = 5µA).
Accuracy: The absolute accuracy is 0.1% of the full scale + 0.1% of the reading.

Linearity: Less than one least significant bit.
Common-mode voltage: 200V.
Common-mode rejection ratio: greater than 70dB at DC and 60Hz.
Inter-channel rejection ratio: 80dB from DC to 1kHz.
Input impedance: 250 ohms.
Input filter response: 325Hz.
Conversion time and update rate: The conversion speed per channel is 0.5 milliseconds, and the update rate for 4 channels is 2 milliseconds.

Isolation feature: There is an isolation voltage of 1500V RMS between the field side and the logic side.
Power consumption: 25mA of current is drawn from the +5V bus on the backplane, and 100mA of current is drawn from the isolated +24V backplane bus.
Operating temperature range: -40°C to +85°C (standard range).
