Output Signal Characteristics
The 44A729581-001 provides four independent current loop outputs for field devices. Each channel sources current directly to the load without external power. The module includes built-in open-loop detection for each output channel. Consequently, you will know immediately if a field wire breaks or disconnects.
Channel Isolation and Protection
This analog output module features individual channel-to-channel isolation. Each output withstands 500V AC between channels and ground. The module also includes short-circuit protection on all output terminals. Therefore, accidental wiring faults will not damage adjacent channels or the backplane.
Resolution and Conversion Accuracy
The 44A729581-001 delivers 12-bit resolution across the full output range. Each count equals approximately 4.88 microamps for precise current control. The module holds its output value between updates without any drift. Hence, your actuators receive stable control signals during normal operation.
Power Requirements and Energy Consumption
This output module draws power from both the backplane and an external source. It consumes 200 mA at 5V DC from the backplane. The module also requires 100 mA at 24V DC for loop power. No battery or energy storage components exist on this unit.
Installation and Calibration
Mount the 44A729581-001 into a standard GE rack slot securely. Connect your field actuators to the removable terminal block using shielded cable. Perform a loop calibration before placing the module into active service. Always verify output wiring matches your selected current range configuration.
