The Allen-Bradley 1771-E1C PLC 5 Analog Input Expander is designed for cost-effective expansion of analog inputs in programmable controllers. It integrates seamlessly in a 1771 I/O rack, offering eight single-ended 12-bit inputs with selectable voltage and current ranges, including +1 to +5V DC and 4-20mA. The module features a high accuracy with a deviation of just ±0.05% for voltage and ±0.07% for current, robust over-voltage and current protection, and circuit isolation up to 1500V RMS, making it a reliable choice for industrial environments with operational temperatures ranging from 0°C to 60°C.
