Allen-Bradley 1756-PLS/B ControlLogix Programmable Limit Switch Module

Allen-Bradley 1756-PLS/B ControlLogix Programmable Limit Switch Module

Description

The ControlLogix PIS module energizes and deenergizes an output based onresolver position. For example, the PIS module can monitor machine positionvia a resolver and activate actuators at various limit switch Low Iimit and HighLimit setpoint positions.

When the axis position measured by a resolver reaches the predefined LowLimit setpoint, the PLS module energizes the output. As the axis continues itsrotation, the resolver reaches the High Limit setpoint, and the PLS moduledeenergizes the output.

Programmable Limit Switch Module (3-20 Pin)：

• Mounts in a ControlLogix® chassis
• Requires either a removable terminal block (RTB) or a Bulletin 1492 wiring interface module (IFM) to connect all field-side wiring
• Inherent time-stamping capabilities for sequence of events (SOE) applications
• Comprehensive I/O diagnostics for detection of both system and field-side failures
• Removal and insertion under power (RIUP) for ease of maintenance
• Electronic keying to help prevent replacement errors
• I/O wizards in the Studio 5000® (formerly called RSLogix™ 5000) Logix Designer application enable quick and easy module configuration
• Configurable flow meter modules
• High-speed counter modules
