FUNCTIONAL DESCRIPTION:

IC660BBD025 is a DC 32-Circuit Source/Sink I/O Module manufactured and designed by General Electric as part of the Mark II Series used in GE Speedtronic Control Systems. A DC 32-Circuit Source/Sink I/O Block is an intelligent, configurable module that interfaces the controller to devices that provide or accept a binary signal. The blocks are compatible with a wide range of input devices, including both 2-wire and 3-wire electronic proximity switches. Outputs may be low-power control and indicating devices such as relays, contactors, and lamps. These blocks have 32 identical discrete I/O circuits, each easily configured to be an input, an output, or an output with feedback. This flexibility provides maximum design and application efficiency. Each circuit contains built-in protection when used as an output, protecting the driver while allowing short-time surges. It also protects against shorted loads caused by wiring errors. Block LEDs verify proper block operation and CPU communications. Individual circuit LEDs on the logic side indicate voltage present on inputs and outputs.

FEATURES OF DC 32-CIRCUIT SOURCE/SINK I/O MODULE:

32-Circuit DC I/O Blocks interface to a wide range of input devices, including both 2-wire and 3-wire electronic proximity switches. Outputs may be low-power control and indicating devices such as relays, contactors, and lamps.

These blocks have 32 identical discrete I/O circuits, each easily configured to be an input or an output. Output circuits can be directly connected to input circuits without the use of other components or inversion of logic states. This flexibility provides maximum design and application efficiency.

Each circuit contains built-in protection when used as an output, protecting the driver while allowing short-time surges. It also protects against shorted loads caused by wiring errors. Block LEDs indicate proper block operation and CPU communications. Fault reporting can be enabled or disabled circuit by circuit. Additional configurable features include:

• Output Pulse Test Capability
• Selectable Input Filter Time from 1mS to 100mS
• Output power-up defaults
• Output Hold Last State or default
• CPU Redundancy type
• Bus Switching Module control

INPUTS AND OUTPUTS:

The block can be configured as an inputs-only, outputs-only, or combination block. Regardless, the block always sends 4 bytes of data each bus scan and accepts 4 bytes of data each bus scan. If the block is configured as an inputs-only block, all circuits must be inputs. The block will use 32 input references and NO output references. If the block is configured as an output-only block, all circuits must be regular outputs; no feedback analysis can be performed. The block will use 32 output references and NO input references.

If the block is configured as a combination block, it can have any mix of input and/or output circuits. The block will use 32 input references and 32 output references. The actual state of each output circuit will be returned to the CPU in the corresponding input reference location. The CPU can monitor the feedback state to verify (after an appropriate delay) that the output switching device has operated properly and that the load has the proper voltage and current applied.

FREQUENTLY ASKED QUESTIONS:

What is a DC 32-Circuit Source/Sink I/O Module?

A DC 32-Circuit Source/Sink I/O Module is an industrial device used in automation systems to interface digital signals between field devices and a central controller, such as a PLC (Programmable Logic Controller). It features 32 discrete channels that can function as either input or output points, depending on the configuration.

What is the input/output isolation level of the module?

Most DC 32-Circuit Source/Sink I/O Modules are designed with electrical isolation between the input/output channels and the system logic to prevent ground loops, reduce electrical noise, and protect the controller from voltage spikes. The isolation level is typically around 1500V to 2500V AC RMS, depending on the model and manufacturer.

What is the maximum current rating for output channels?

Each output channel on the module usually supports a maximum current output ranging from 0.5 A to 2 A, depending on the design. For high-current devices, some modules support current sharing or include external relays.
