Fanuc IC655ALG566 PLC

This Series Five 2 Channel Analog Output module provides two output channels, each capable of

converting 12 bits of binary (digital) data to an analog output for use as required by your application.

This module provides both voltage and current outputs. Connections for field wiring are made to the 20 screws on the removable terminal block. These outputs can be voltage (0 to +lO V), or current (4 to 20 mA). Resolution of the converted signal is 12 bits binary (1 part in 4096). Twelve LEDs on the faceplate provide a 12,bit binary display which can indicate resolution of the output as a percent of full scale.

The module can drive either single ended or differential voltage devices or current devices. User

devices to be driven are optically isolated from the base unit power supply by opto-isolators on the module. An Analog output module consumes 32 consecutive Output points, beginning with the first output reference assigned to the slot in which the module is installed.

In addition to the 12 LEDs described above, there are three other LEDs viewable on the faceplate. The GEN LED is on when the module address is mapped into either the Ol+ or 02+ status table; the DIAG LED when on, indicates that an internal failure has been detected by the module. The ADR LED, when on, indicates that the 8 LEDs in the two columns to the right have been instructed by the CPU to display the starting address for the module in BCD format.
