Model Explanation

B883 = Modicon 800 intelligent special I/O module; 200 = 10 channels dedicated for thermocouples, distinction between 0XX pulse counting, 1XX absolute value cam series, independent thermocouple acquisition configuration architecture. Technical Specifications

Sampling Channel: 10 isolated analog inputs, each module occupies 3 consecutive input registers of the PLC

Temperature Measurement Type: Software configuration compatible with B/E/J/K/R/S/T/N eight standard thermocouples. It can also directly sample -20 to +80 mV millivolt signals

Measurement Accuracy: Temperature resolution 1℃/1℉, millivolt resolution 0.1mV, built-in hardware cold junction automatic compensation

Backplane Power Consumption: 5VDC @ 400mA, standard single-slot chassis footprint

Power-on Initialization: Self-check and cold junction calibration can be completed in up to 13 seconds

Dimensions: 51 (W) × 203 (H) × 280 (D) mm, net weight 0.58kg

Environmental Indicators: Operating temperature 0~60℃, storage temperature -40~85℃, humidity < 80% RH without condensation, IP20 cabinet installation

Interface and Matching Base

Special matching wiring base: AS-8643-000, cannot be interchanged with B883-001/002/101 universal base.

Core Functions

Full-channel software free switching of thermocouple models or millivolt input; hardware integration of cold junction compensation to eliminate environmental temperature drift at connection terminals; channel open-circuit fault self-check, panel fault LED alarm; 10-channel temperature data automatic conversion and input into PLC registers without external transducer; full parameter PLC program configuration, no hardware code setting. Applicable scenarios

Heat treatment quenching furnaces, kiln temperature control, temperature measurement for chemical reaction vessels, temperature control for plastic and rubber extrusion machine barrel, multi-point temperature collection for metallurgical heat treatment production lines.

Operation and Maintenance

Directly insert Modicon 800 standard I/O slot; priority check for thermocouple breakage is to verify the positive and negative poles of the compensating cable and the shielding grounding; check for abnormal cold end data to verify the installation environment temperature of the base; the same rack can accommodate B875 analog quantity and B883 counting/cam series modules.
