Environmental Parameters: Operating 0~60℃, Storage - 40~85℃, Humidity < 80% RH without condensation, IP20 cabinet installation

Interface and Matching Base

Special Wiring Base AS-8643-000, same as AS-B883-200 universal, cannot be compatible with B883-0XX/1XX series cams, counter modules bases.

Core Function

Full Channel Software Switching of American Standard / National Standard Pt100 parameters, no need for hardware dip switch; Built-in automatic compensation of three-wire lead resistance, eliminating long cable voltage drop error; Single-channel open circuit fault self-check, panel fault LED indicator; Temperature measurement data automatically converted to engineering temperature values and stored in PLC registers, no need for external RTD transducer; Double-precision mode programmable switching, balancing conventional temperature measurement and precise temperature control conditions. Applicable scenarios

The extruder barrel is precisely temperature-controlled, and the chemical reaction vessel has multi-point temperature measurement. The heat treatment continuous furnace, the fiber spinning box body has temperature control, and the paper drying roller temperature is collected.

Operation and Maintenance

Plug directly into the Modicon 800 standard I/O slot; priority check for temperature drift is the resistance value of the three-wire thermoresistor wiring, shielding grounding; check for sensor breakage by troubleshooting the thermoresistor body and the terminal block at the base; the frame can be mixed-installed with B875 analog quantity and B883 cam / counter full series modules.
