GE Fanuc IC695ALG808 RX3i Analog Output Module

IC695ALG808 Analog Current/Voltage Output Isolated Module

Description

The Analog Current/Voltage Output Isolated module, IC695ALG808, provides eight configurable voltage or current output channels. The analog channels can be configured for the following output ranges:

• Current: 0 to 20mA, 4 to 20mA
• Voltage: ±10 Vdc, 0 to 10 Vdc

This module must be located in an RX3i Universal Backplane. It can be used with various terminal blocks, including:

• Box-style (IC694TBB032)
• Extended Box-style (IC694TBB132)
• Spring-style (IC694TBS032)
• Extended Spring-style (IC694TBS132)

Extended terminal blocks provide the extra shroud depth needed for shielded wiring. Terminal blocks are ordered separately.
