Allen Bradley 1756-HYD02 ControlLogix Hydraulic Servo Module

Product Overview

The Allen Bradley 1756-HYD02 functions as a high-precision interface between your ControlLogix system and hydraulic actuators. This 2-axis module provides closed-loop control, utilizing sophisticated PID algorithms with feed-forward and directional scaling to manage complex hydraulic motion. We offer this unit as 100% Brand New and original factory sealed, ensuring maximum reliability for your critical infrastructure.

Technical Specifications

The 1756-HYD02 integrates seamlessly into any standard ControlLogix chassis slot. The following table highlights its core technical capabilities:

Engineering Advantages

• Precision Motion Control: The 32-bit floating-point gain resolution eliminates rounding errors during high-speed calculations. This ensures smooth, jitter-free movement for hydraulic cylinders even in high-tonnage applications.

• Optimized Response Times: With selectable loop rates up to 4kHz, the module allows engineers to tune the system for ultra-fast response. This capability solves the common industrial pain point of lag in hydraulic positioning.

• Rugged Signal Integrity: The optically isolated registration inputs protect the module from ground loops and electrical noise common in heavy industrial environments. The solid-state isolated relay contacts for discrete outputs provide a wear-free switching solution that outlasts mechanical alternatives.

• Simplified Installation: The module fits into any available slot in the 1756 Chassis. Utilizing the 1756-TBCH Removable Terminal Block allows technicians to wire the system before installing the module, reducing downtime during maintenance or commissioning.

FAQs

Q: Can a single ControlLogix controller manage multiple 1756-HYD02 modules?

A: Yes. A single controller supports up to 32 axes. Since each 1756-HYD02 manages 2 axes, you can install up to 16 of these modules in a single system to handle complex, multi-axis hydraulic synchronized motion.

Q: What types of feedback sensors does the module support?

A: The 1756-HYD02 specifically interfaces with Linear Displacement Transducers (LDT) using PWM or Start/Stop signals. It supports both rising and falling edge triggers for maximum sensor compatibility.

Q: Is the 1756-HYD02 compatible with existing 1756 chassis?

A: This module occupies exactly one slot width and operates within the standard ControlLogix backplane architecture. It requires either the 1756-TBCH or 1756-TBS6H terminal block for field-side wiring connections.

Q: How does the module handle directional scaling?

A: The firmware includes directional scaling within the PID loop to account for the inherent physical differences in hydraulic cylinder speed and force between extension and retraction, providing symmetrical performance in both directions.
