As an intelligent co-processor, it handles complex parison profile management and servo-loop execution autonomously, effectively offloading these compute-intensive tasks from the main SLC 500 processor. This module is compatible with various molding architectures, including continuous extrusion, reciprocating screw, and accumulator head systems.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFour independent axes of PID control, supporting flexible configuration for parison and accumulator push-out operations.\u003c\/li\u003e\n\u003cli\u003eHigh-speed loop update rate of 100 microseconds for real-time responsiveness.\u003c\/li\u003e\n\u003cli\u003e256-point profile resolution with advanced interpolation for consistent wall thickness and part quality.\u003c\/li\u003e\n\u003cli\u003eDynamic profile adjustment capability, allowing for weight modification without compromising the integrity of the established parison shape.\u003c\/li\u003e\n\u003cli\u003eIntegrated 14-bit resolution for both analog inputs and outputs, ensuring high-precision signal processing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\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\u003eSLC 500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eBlow Molding Specialty Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog I\/O\u003c\/td\u003e\n\u003ctd\u003e4 Inputs \/ 4 Outputs (14-bit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital I\/O\u003c\/td\u003e\n\u003ctd\u003e4 Inputs \/ 4 Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExcitation Output\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConversion Rate\u003c\/td\u003e\n\u003ctd\u003e10 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5V)\u003c\/td\u003e\n\u003ctd\u003e110 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (24V)\u003c\/td\u003e\n\u003ctd\u003e85 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoop Update Time\u003c\/td\u003e\n\u003ctd\u003e100 µs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e500V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the SLC 500 chassis power is disconnected before installing or removing the 1746-BLM module.\u003c\/li\u003e\n\u003cli\u003eHandle the module using proper ESD precautions to prevent damage to sensitive internal circuitry.\u003c\/li\u003e\n\u003cli\u003eSecure the module firmly into the designated SLC 500 I\/O slot to ensure reliable backplane communication.\u003c\/li\u003e\n\u003cli\u003eRoute signal wiring away from high-voltage cables or high-EMI sources to maintain signal integrity for the 14-bit analog channels.\u003c\/li\u003e\n\u003cli\u003eVerify that the backplane power supply capacity is sufficient to support the 110 mA (5V) and 85 mA (24V) requirements of this module.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat type of blow molding machines does the 1746-BLM support?\u003c\/h3\u003e\u003cp\u003eThis module is versatile and supports continuous extrusion, reciprocating screw, and accumulator head blow molding machinery.\u003c\/p\u003e\u003ch3\u003eDoes the module require the SLC 500 processor to handle the PID loops?\u003c\/h3\u003e\u003cp\u003eNo, the 1746-BLM functions as an intelligent co-processor.
