1771-DS
The Allen-Bradley 1771-DS is a latching digital input module from the PLC-5 series, designed for reliable detection of discrete signals in industrial automation systems. It features 8 input channels operating within a voltage range of 10 to 27 Volts DC. The module latches input states, allowing it to retain signal information until it is reset, which is useful for monitoring transient or momentary events. Logic levels are defined as 10-27 VDC for a logical high (1) and 0-4 VDC for a logical low (0). This module is compatible with standard 1771 I/O chassis and is suitable for diverse control applications.
