Product Introduction
IC694ALG442 Module Features: Outputs can be configured to either Hold Last State or to reset to the low end of their range if system power is interrupted. Outputs can also be configured to operate in ramp mode on command from the application program. In ramp mode, the output channel transitions to a new value over a period of time, rather than taking the new value immediately.

Voltage: 0-5V DC, 0-10V DC, ±5V DC, ±10V DC
Current: 0-20mA, 4-20mA
Resolution: 14 bits (voltage), 13 bits (current)
Accuracy: ±0.2% of Full Scale (25°C)

3. General specifications
Isolation
Between the input channel and the backplane logic: 500V AC, lasting for 1 minute.
Between the output channel and the backplane logic: 500V AC, lasting for 1 minute.
Note: Input channels are not isolated from each other, and output channels are not isolated from each other. There is no isolation between the input and output channels.
Power consumption: +5V DC (from the backplane), maximum 275mA.
LED indicator lights: Status and error indicator lights are provided on the module.
Connection: Connect to the field device via a detachable 40-pin front connector (typically using IC693CBL311 or a similar cable).
Configuration: Configure using PACSystems programming software (such as Proficy Machine Edition), without the need for hardware DIP switches. All parameters (range, filtering, alarm, etc.) are set through the software.
IC694ALG442 Advantages and Limitations
Advantages
Space-saving: By integrating input and output functions into one, the number of modules and rack size are reduced.
Flexibility: Each channel can be independently configured as either voltage or current mode, adapting to a variety of sensors and actuators.
High precision: The 16-bit input resolution provides excellent measurement accuracy.
Easy to configure: Fully software-configured, simplifying setup and maintenance.
Limitations/Precautions:
Non-isolated channels: There is no isolation between input channels, output channels, or between input and output. This may be a limitation in applications where there is a high common-mode voltage or where isolation between channels is required.
Dependent on software and cables: The correct programming software and dedicated front connector cables must be used.
Discontinued status: This module is a discontinued product. Emerson has replaced the RX3i product line with an updated series.
