The Allen-Bradley 1756-TBCH is a versatile analog input module designed for the ControlLogix platform, offering eight differential input channels with full support for both voltage and current signals, as well as Highway Addressable Remote Transducer (HART) communication protocols. It supports configurable current inputs such as 0-20 mA and 4-20 mA, alongside voltage inputs that include ±10VDC, 0-5 VDC, 1-5 VDC, and 0-10 VDC. This module features a 16-21 bit resolution and requires a power supply of 300 mA at 5.1 VDC and 135 mA at 24 VDC, consuming a total backplane power of 4.77 Watts. Additionally, it boasts a robust design with overvoltage protection of up to 30 VDC for voltage signals and 8 VDC for current, while providing efficient HART communication capabilities for enhanced system integration and process diagnostics.
