The module processes two-axis closed-loop hydraulic control using PID with feed-forward and directional scaling. It supports 32-bit floating-point gain resolution, ±10 V analog output, and optically isolated registration inputs. Control execution is synchronized through the ControlLogix chassis backplane with selectable update rates from 500 Hz to 4 kHz.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cp\u003eNo formal suffix segmentation is defined for\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e1756-HYD02\u003c\/strong\u003e.\u003cbr\u003eThe identifier is treated as a single catalog-level module code within the 1756 ControlLogix hydraulic servo family.\u003cbr\u003eAll functional behavior is determined by firmware and chassis configuration rather than suffix expansion.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003ctable class=\"w-fit min-w-(--thread-content-width)\"\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth class=\"last:pe-10\"\u003eParameter\u003c\/th\u003e\n\u003cth class=\"last:pe-10\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1756-HYD02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.23 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e5.5 W (dissipation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eHydraulic Servo Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e1756 ControlLogix\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxes per Module\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxes per Controller\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Output\u003c\/td\u003e\n\u003ctd\u003e±10 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Output Resolution\u003c\/td\u003e\n\u003ctd\u003e16 bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eServo Loop Type\u003c\/td\u003e\n\u003ctd\u003ePID with feed-forward and directional scaling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain Resolution\u003c\/td\u003e\n\u003ctd\u003e32-bit floating point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUpdate Rate\u003c\/td\u003e\n\u003ctd\u003e500 Hz to 4 kHz selectable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLDT Input\u003c\/td\u003e\n\u003ctd\u003ePWM, start\/stop edge detection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRegistration Input\u003c\/td\u003e\n\u003ctd\u003eOptically isolated current sinking input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Outputs\u003c\/td\u003e\n\u003ctd\u003eSolid-state isolated relay contacts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Output Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5 V)\u003c\/td\u003e\n\u003ctd\u003e700 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (24 V)\u003c\/td\u003e\n\u003ctd\u003e2.5 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Blocks\u003c\/td\u003e\n\u003ctd\u003e1756-TBCH, 1756-TBS6H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Location\u003c\/td\u003e\n\u003ctd\u003eControlLogix chassis (any slot)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Width\u003c\/td\u003e\n\u003ctd\u003e1 slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eControlLogix Backplane Bus Synchronization Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe 1756-HYD02 executes real-time axis control through the ControlLogix backplane scheduling layer.
