GE IC660BBA025 Current-source Analog Output Blocks

GE IC660BBA025 Current-source Analog Output Blocks

Description

Current-source Analog Output Blocks have 6 output circuits for devices that accept 4 to 20mA signals. Outputs 5 and 6 can also be used for voltage applications. Two Current-source Analog Output blocks are available:
115 VAC Current-source Analog Output Block (IC66*BBA105)
24/48 VDC Current-source Analog Output Block (IC66*BBA025) These blocks are identical except for the power supply

Features 

Block features include: 

Six 4-to-20 mA analog output circuits 

No calibration required for operation 

Software configurable 

Advanced diagnostics 

Dedicated Bus Switching Module control

These blocks provide power to all circuits; no separate power is required for 4-20mA signals. Each output provides power and control of a 4-to-20mA current loop. This power is isolated from the rest of the block. The outputs and BSM circuitry are electrically common. Output accuracy is 0.15% at 25°C. Output resolution is 6µA.

The block has a dedicated digital output that can be used to drive a Bus Switching Module (IC66*BSM012 only). The outputs and BSM circuitry are electrically common.

Configurable features of these blocks include: 

Output Hold Last State or default 

Circuit scaling to engineering units values 

Output feedback checking and feedback time 

CPU Redundancy

Fault reporting can be enabled or disabled circuit-by-circuit. These blocks automatically perform the following diagnostic checks: 

Output Overrange and Underrange 

Output Feedback

Installation Instructions

Carefully inspect all shipping containers for damage. If any equipment is damaged, notify the delivery service immediately. Save the damaged shipping container for inspection by the delivery service. After unpacking the equipment, record all serial numbers. Save the shipping containers and packing material in case it is necessary to transport or ship any part of the system.

Block Mounting

Genius I/O blocks are considered "open equipment" and therefore must be installed within a protective enclosure. They should be located in an area that is clean and free of airborne contaminants. There should be adequate cooling airflow. The block can be mounted right side up, or upside down. Leave at least 2 inches of space between blocks. Mount the block by drilling two screw or bolt holes for 8-32 hardware. Position the block so that the notches in the upper and lower flanges line up with the mounting holes. Mount the block using 8-32 screws. Use star washers to provide ground integrity.
