The Allen-Bradley 1756-PLS ControlLogix Programmable Limit Switch is expertly designed to monitor machine positions via a resolver, efficiently manage actuator activation at various limits, and precisely handle low and high limit setpoints. This module features 16 outputs working within a range of 10 - 31.2V DC, offering a maximum output of 1A per output, while organized into four groups of four outputs, each with separate power and common lines. It also provides 16 single-ended inputs at the same voltage range and configuration, catering to versatile industrial applications with seamless integration into a ControlLogix chassis through a Removable Terminal Block. Operating reliably in environments from 0 to 60 °C and 0-95% noncondensing humidity, the module ensures optimal performance with a thermal dissipation of 6.35 to 9.56 BTU/hr, safeguarding against configuration loss and electrical arcing during insertion or removal when the backplane power is active.
