HE670ADC840

The HE670ADC840 from Horner Electric serves as an analog input module within the PLC I/O series. Capable of managing 8 individual channels, this module operates effectively across a current range of 4 to 20 milliamperes, making it suitable for a diverse array of monitoring and control tasks. Its consumption is specified at 130 milliamperes sourced from the backplane, which helps maintain consistent functionality in the system it integrates into.

With an input impedance of 100 ohms, the module is designed to minimize loading effects on signal sources. It ensures safety and reliability through channel-to-channel isolation rated at 400 volts DC and channel-to-bus isolation rated at an impressive 1,000 volts DC. This degree of isolation is crucial in environments requiring robust protection against electrical interferences.

The output format is dictated by the corresponding bus interface unit, providing flexibility in how the signals are interpreted or processed downstream. For accuracy, the module achieves a maximum error margin of +/- 1% of full scale when operating at 25 degrees Celsius, along with a resolution of 12 bits, ensuring the fidelity of the data captured.

Designed to function efficiently in a relative humidity range of 5% to 95% without condensing, it is also rated for operation in temperatures between 0 and 75 degrees Celsius, making it well-suited for industrial environments that may experience fluctuations in climate. The HE670ADC840 module combines precision and versatility for various automation applications.
