PACSystems / RX3i / ANALOG OUTPUT
IC695ALG704
PACSystems RX3i 4-Channel Analog Output Module
The IC695ALG704 is a four-channel non-isolated analog output module for the PACSystems RX3i platform. Each channel can be configured for voltage or current output, making the module suitable for control loops where PLC output data must be converted into proportional field signals for process or machine equipment.

01 / TECHNICAL PROFILE
Four outputs.
Multiple signal ranges. The module provides four independently configurable analog output channels. Voltage and current ranges can be selected through software configuration rather than physical module jumpers. The output architecture includes configurable scaling, offsets, alarm handling, clamping and output behavior when the PLC changes from Run to Stop. |

02 / SYSTEM REQUIREMENTS
Power and
platform compatibility IC695ALG704 is designed specifically for the PACSystems RX3i architecture. Installation planning should account for the universal backplane requirement, CPU firmware level and separate field-side power supply. |
|
|
03 / ELECTRICAL CHARACTERISTICS
Designed around
configurable analog control The output channels support both voltage and current signaling, allowing the same module family to serve different control architectures without changing the basic hardware platform.

04 / CONTROL APPLICATIONS
Where analog output
becomes a control signal The module is suited to RX3i control architectures where the PLC must continuously command proportional field devices. Typical control functions include regulating process variables and positioning equipment through voltage or current signals. Common field applications include control valves, positioners, dampers, louvers and signal interfaces where a programmable analog output is required. |
|
|
05 / MAINTENANCE CONTEXT
When an ALG704 replacement
can affect process continuity The IC695ALG704 is normally considered for replacement when an RX3i analog output channel no longer produces the commanded voltage or current signal, when channel diagnostics report a fault, or when the installed module has suffered an electrical or hardware failure. Because analog outputs may directly command valves, positioners, dampers, louvers and other proportional devices, a failed channel can prevent the associated control element from reaching its required operating position. In a running process, this may contribute to unstable regulation, reduced production capability or a forced interruption while the control path is restored. Before replacing the module, the field signal type, terminal block arrangement, external 24 VDC supply, RX3i CPU compatibility and configured output range should be checked carefully. |
REPLACEMENT CHECK
01 Match IC695ALG704 and the complete installed configuration.
02 Confirm the required voltage or current output range.
03 Verify the external +24 VDC field supply.
04 Check the RX3i CPU firmware and Universal Backplane.
05 Confirm terminal block compatibility before installation.

FIELD WIRING CONSIDERATION
The IC695ALG704 uses a terminal block for field connections, and the terminal block is ordered separately. Extended terminal blocks provide additional shroud depth for shielded wiring arrangements. The module is non-isolated at the analog channel level. Cable shields should be handled according to the installation grounding arrangement rather than assuming channel-to-channel isolation. When replacing an installed unit, matching the existing terminal-block style can simplify the physical replacement process and reduce wiring changes. |

06 / CONTROL FEATURES
More than
simple analog output The configuration model includes diagnostic and control functions intended to make the analog output channels more practical in a PLC-controlled system. |

07 / RX3i ANALOG OUTPUT FAMILY

and its related output platform The IC695ALG704 shares its core analog-output architecture with other RX3i output modules, while the number of available channels and communication capabilities differ between models. |

08 / BUYER QUESTIONS
Before ordering
IC695ALG704 The important purchasing questions are usually related to system compatibility, signal range, field power and the physical terminal arrangement. |
Q1 — Can IC695ALG704 replace a failed RX3i analog output module without changing the control philosophy?
It can be considered when the existing system requires the same four-channel voltage/current analog-output function and the surrounding RX3i architecture is compatible. The replacement should be checked against the installed configuration, field signal ranges, terminal block and CPU requirements before the module is exchanged.
Q2 — What should I check if IC695ALG704 is being purchased for a 4–20 mA control loop?
Confirm that the field device is designed for a 4–20 mA command signal, that the selected channel is configured for the required current range, and that the available external field supply and output-load conditions are suitable. For the module, the specified maximum current load is 850 Ω at Vuser = 20 V.
Q3 — Why is the external 24 VDC supply important when installing IC695ALG704?
The module does not obtain its field-side 24 VDC through the RX3i Universal Backplane TB1 connection. An external +24 VDC source must be connected directly to the module terminal block, with the specified supply range of +19.2 to +30 VDC.
Q4 — What kind of production problem could lead a customer to search for IC695ALG704 urgently?
A failed analog output can stop a PLC from delivering the required command signal to a proportional valve, positioner, damper, louver or another analog-controlled device. Depending on the process, that can lead to poor regulation, equipment remaining in an undesired state or an interruption while the control channel is restored.
Q5 — Is IC695ALG704 suitable when the existing system needs more than four analog output channels?
IC695ALG704 provides four channels. If the application requires eight voltage/current analog outputs in the same RX3i family, IC695ALG708 is the corresponding eight-channel module. The final selection should follow the actual channel count and configured control architecture.
