IC693ALG221 - 4 Channel Analog Input Module

SPECIFICATIONS

Part Number: IC693ALG221
Manufacturer: GE Fanuc
Series: 90 - 30
Function: Analog Input Module
Input Current Ranges: 4 to 20 mA & 0 to 20 mA

IC693ALG221 is an Analog Input Module and is part of the series 90 - 30 programmable logic control system. This is a component module that also serves as an analog input module. This module has four (4) input channels that accept 0-20 mA and 4-20 mA input signals from field instruments and devices. This module has an integrated Analog-Digital converter (ADC) that allows the PLC to process and condition the signal before using it in the user application.

• The analog input module has a 12-bit input resolution, with a resolution of 4 A (1 LSB = 4 A) for 4-20 mA input signals and 5 A (1 LSB = 5 A) for 0-20 mA input signals for each input range. With a common-mode voltage of 200V, it has an absolute accuracy of 0.1 percent full scale + 0.1 percent reading.

• This module also offers linearity of 1 Least Significant Bit and a 325 Hz input filter response. The default channel setting on the input module is 4-20 mA. When a 4-20 mA signal is received, the module translates the signal range to 0-32000, a unitless measurement that represents the input register's value.

• Zero represents 4 milliamperes, whereas 32000 represents 20 milliamperes. The 0-20 mA input range is also covered by this internal conversion. Hardware configuration of the input signal type is done by shorting particular terminals in the module's removable terminal block.

• One for channels one and two, and the other for channels three and four, are provided as range jumpers. In a PLC system, the 4-Channel Analog Current Input Module can be installed in practically any I/O rack.

• The voltage from the power source is routed through a regulator/inverter to supply the operating voltage to the module. To reduce noise and capacitive loading, make sure all field connections are wired using graded, twisted cables.

• The main power source of the module is isolated +24 Volts DC power supplied by the PLC. To eliminate externally generated noises, the IC693ALG221 4-Channel Analog Current Input Module provides electrical and optical isolation between the field wiring and the backplane.
