Product Details
The 12/24 VDC Positive Output Module (IC670MDL740) provides a single group of 16 discrete outputs. The outputs are positive logic or sourcing–type outputs. They switch the loads to the positive side of the DC supply, and thus supply current to the load.
Power Sources:The power that runs the module itself comes from the power supply in the Bus Interface Unit. An external source of DC power must be provided for the switches that power the loads. Within the module, the external power supply is connected to a 5A fuse. During operation, the module monitors this power to be sure it is above 9.8VDC. If not, it is interpreted as a fault by the Bus Interface Unit.
LEDs:Individual LEDs (logic side), visible through the transparent portion of the module top, indicate the on/off status of each output. The PWR LED is on when field and backplane power are present and the module fuse is not blown.
Host Interface:Intelligent processing for this module is performed by the Bus Interface Unit or elsewhere in the system. This includes configuring features such as output default and fault reporting. The module has 16 bits (two bytes) of discrete output data. A Bus Interface Unit is required to obtain this output data from the host and/or local processor.

The 240VAC Input Module (IC670MDL241) provides two isolated groups of 8 discrete inputs each.
Power Sources:The power that runs the module itself comes from the power supply in the Bus Interface Unit. A separate external 240VAC supply is needed to power each isolated group of input devices. Module inputs respond to voltage levels from 0 VAC to 265 VAC.
LEDs:Individual logic-side LEDs, visible through the transparent portion of the module top, indicate the on/off status of each input. The PWR LED is on when field and backplane power are present.
Host Interface:Intelligent processing for this module is performed by the Bus Interface Unit or elsewhere in the system. This includes configuring features such as input defaults and fault reporting. The module has 8 bits (one byte) of discrete input data. A Bus Interface Unit is required to provide this input data to the host and/or local processor.
Module Operation:A network of resistors and capacitors establishes input thresholds and provides input filtering. Optoisolators provide isolation between the field inputs and the module's logic components. Data from all 16 inputs is placed into a data buffer. The module's circuit LEDs show the current states of the 16 inputs in this data buffer. Parallel–to–seri al converters change input data from the data buffer into the serial format needed by the Bus Interface Unit.
