The Allen-Bradley 931S-C124 931S smart dual channel converter is a signal conditioning device with HART 0.5 to 2.5 kiloHertz signal compatibility that is built enhance the signal quality between the field devices and the control system. The 931S-C124 signal conditioner uses a 5-way isolator to deliver the high-quality signals from the field devices and the control system by isolating, reproducing, and transmitting a higher-quality signal from the device to the control system than would otherwise be possible. It has removable terminals that offer error-proof termination during field-installation, and it does not require any field configuration. The 931S-C124 signal conditioner has a 20 to 30 Volts DC supply range and 60 milliamps of power consumption at 20 milliamps. It has 2 passive input channels with input current ranges of 0 to 20 milliamps and of 4 to 20 milliamps and a sensor voltage rating of 17 Volts at 20 milliamps.

The Allen-Bradley 931S-C124 signal conditioner is HART transparent and it allows for bidirectional HART signal transmission between the input and output sides. It has 2 active output channels that produce 0 to 20 milliamps and 4 to 20 milliamps rated HART digital signals, and it has a 300 Ohms per channel of impedance rating. The 931S-C124 signal conditioner has an accuracy value of 0.1% and a 0.5-millisecond maximum response time. It comes with a 5-way galvanic isolator with an isolation voltage rating of 2 kilovolts and a withstand rating of 4 kilovolts. The 931S-C124 signal conditioner comes with an IP 20 rated enclosure, and it has a -20 to 60 degrees Celsius rated operating temperature range. The 931S-C124 signal conditioner weighs approximately 172 grams, and it measures 0.49 x 4.58 x 4.47 Inches.
