The IC695ALG708 output module is an analog output module from GE Fanuc that has been designed and manufactured in the RX3i PACSystems series to be used with the RX3i PACSystems PLCs. This analog output module features 8 output channels that can all be independently configured by the operators to be either voltage output channels or current output channels. The different kinds of outputs can be used to handle different applications and to connect to different devices in the RX3i PACSystems PLC. When any of the outputs on the IC695ALG708 analog output module are configured as voltage outputs, they can operate with output voltage ranges of 0 Volts to 10 Volts or -10 Volts to +10 Volts. When any of the outputs on the IC695ALG708 analog output module are configured as current outputs instead, these outputs can operate with output current ranges of 0 milliamps to 20 milliamps or 4 milliamps to 20 milliamps.


All 8 of the output channels on the GE Fanuc RX3i PACSystems IC695ALG708 analog output module update quickly. The update time is only 8 milliseconds maximum per output channel. The maximum output load that the IC695ALG708 analog output module can handle is a load of 850 Ohms and the module’s maximum power dissipation rating during normal operation is 7.25 Watts. This module uses an external power supply that can provide DC power in the range of 19.2 to 30 Volts DC. The power consumption ratings of the IC695ALG708 analog output module are 375 milliamps at 3.3 Volts DC voltage and 315 milliamps at 24 Volts DC isolated voltage.

Voltage Range: 19.2V to 30V (24V nominal) Current required for ALG704: 120mA maximum Current required for ALG708:  210mA maximum

Current required for ALG728:190mA maximum


+/-10V: 15.9 bits,  0 to 10V: 14.9 bits,  0 to 20mA: 15.9 bits,

4 to 20mA : 15.6 bits

HART Communications

Version 5.0 HART protocol supported on module IC695ALG728.

Output Data Format

Configurable as floating point IEEE 32 bit or 16-bit integer in a 32-bit field

Analog Update Rate (Determined by I/O scan time, application dependent)

IC695ALG704 and ALG708: 8 milliseconds (approximate, all eight channels)

ALG728: 16mS with HART (approximate, all eight channels) 8mS without HART (approximate, all eight channels)

HART Data Scan Time (in seconds) The HART data scan can consist of up to four acquisition cycles (similar but asynchronous to the analog scan time).  Each cycle includes a specific set of channels.  Total HART scan

time depends on the number of channels enabed for HART within a specific set of channels, number of retries, enabling/disabling of slot variables, and use and configuration settings of pass-thru commands.

One HART Channel in Group

Each HART Data channel updates every 0.7 second (typical)

Two HART Channels in Group

Each HART Data channel updates every 1.9 seconds (typical)

Three HART Channels in Group

Each HART Data channel updates every 3.0 seconds (typical)

Four HART Channels in Group

Each HART Data channel updates every 4.0 seconds (typical)

Output Overvoltage Protection

Current outputs only:  -30V for 60 seconds, +30V for one hour

Calibrated Accuracy

Accurate to within 0.15% of full scale at 25°C Accurate to within 0. 25% of full scale at 60°C

In the presence of severe RF interference (IC 801-3, 10V/M), accuracy may be degraded to +/-1% FS.

Output Load Reactance

Current: 10µH maximum, Voltage: 1µF maximum

Maximmum Output Load

Current: 850 Ohms maximum at Vuser = 20V Voltage: 2 Kohms minimum
