{"product_id":"allen-bradley-1771-qh-force-control-module","title":"Allen Bradley 1771-QH Force Control Module","description":"\u003cp\u003eThe \u003cstrong\u003e1771-QH\u003c\/strong\u003e is a specialized force control module engineered for the Allen-Bradley PLC-5 automation platform. It functions as a single-axis hydraulic controller, enabling high-speed, transparent transitions between speed control and pressure control modes. This module optimizes machinery performance by delivering fast operations and supporting auxiliary outputs for hydraulic pump controllers and proportional valve amplifiers.\u003c\/p\u003e\n\u003ch3\u003eFunctional Features and Performance\u003c\/h3\u003e\n\u003cp\u003eThe module features a 12-bit binary I\/O resolution equipped with four analog inputs and four analog outputs. It delivers a fast update period of 2 milliseconds for servo loops, position tracking, and pressure measurements. All operational parameters are stored directly within the PLC processor data table, significantly reducing setup time and eliminating the need for frequent recalibration.\u003c\/p\u003e\n\u003ch3\u003eMechanical and Electrical Specifications\u003c\/h3\u003e\n\u003cp\u003eThe unit requires a 1.2 A backplane current at 5 VDC and operates within a frequency range of 47 Hz to 63 Hz. It is protected by a 3 A, 250 V normal-blow fuse and features a thermal dissipation of 21 BTU\/hour with outputs fully energized. The physical dimensions measure 4.5 x 12.4 x 6.3 inches, occupying a single slot within the chassis.\u003c\/p\u003e\n\u003ch3\u003eAccessories and Compatibility\u003c\/h3\u003e\n\u003cp\u003eSystem connectivity relies on the designated 1771-WF wiring arm for secure field termination. For remote applications, the module supports the 1771-PSCC cabling option spanning 5.5 feet. It is engineered for stand-alone deployment within compatible PLC-5 backplane environments while allowing operators to make necessary adjustments during live operation without system shutdowns.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\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\u003e1771-QH\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\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003ePLC-5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eForce Control Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlots Required\u003c\/td\u003e\n\u003ctd\u003e1 Slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Requirement\u003c\/td\u003e\n\u003ctd\u003e1.2 A at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd\u003e4 Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Update Period\u003c\/td\u003e\n\u003ctd\u003e2 ms (Scan, Auto Tune PID and Velocity)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal Dissipation\u003c\/td\u003e\n\u003ctd\u003e21 BTU\/hour (Outputs Full ON)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Frequency\u003c\/td\u003e\n\u003ctd\u003e47-63 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse Rating\u003c\/td\u003e\n\u003ctd\u003e3 A, 250 V, Normal-Blow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWiring Arm\u003c\/td\u003e\n\u003ctd\u003e1771-WF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCabling\u003c\/td\u003e\n\u003ctd\u003e1771-PSCC Remote 5.5 ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4.5 x 12.4 x 6.3 inches (115 x 317 x 160 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.31 lbs (0.60 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: Can parameter adjustments be made while the 1771-QH module is running?
