Schneider ASB846002 Analog Module for Modicon Series 8000

The Schneider ASB846002 converts analog field signals for Modicon Series 8000 PLC systems. You can install this module directly into any standard rack slot. It accepts current or voltage inputs from transmitters and sensors. This module suits temperature, pressure, and flow monitoring applications.

Technical Specifications and Hardware Layout

The Schneider ASB846002 measures 254 mm in height. Its width reaches 48 mm, and the depth equals 178 mm. The Schneider ASB846002 weighs approximately 0.55 kilograms. A single internal PCB holds all signal conditioning and conversion circuits. The module contains no energy storage capacitors or batteries. One 48-pin front connector handles all field wiring connections. Four analog input channels provide signal acquisition for field devices. Eight green LEDs display channel activity and fault status.

Input Specifications and Performance

The Schneider ASB846002 accepts 0 to 20 mA or 4 to 20 mA current signals. It also handles voltage inputs from 0 to 10 V DC. Each channel provides a configurable input impedance of 250 ohms for current mode. For voltage mode, the impedance reaches 100 kohms. The module delivers a 12-bit digital resolution for precise measurements. Accuracy stays within 0.2 percent of full scale at 25°C. Consequently, this module captures process variables with excellent repeatability. An internal low-pass filter removes high-frequency noise from each input.

Installation and Calibration Guidelines

You must insert the Schneider ASB846002 firmly into a standard Series 8000 rack slot. Transitioning to wiring, use twisted-pair shielded cables for optimal signal integrity. The module requires no external power supply for loop-powered transmitters. A DIP switch bank lets you select current or voltage per channel. Eight front LEDs show power, input status, and fault conditions clearly. The operating temperature range spans from 0°C to 60°C reliably.
