Schneider TSXP574823A Dual-Format PL7 Processor

Product Overview

The TSXP574823A executes PL7 programs for Modicon Premium automation systems. You will find this processor in water treatment and material handling plants. It supports both rack-mounted and stand-alone configurations. Additionally, this processor includes a built-in math coprocessor for fast calculations. Therefore, it handles complex PID loops without additional hardware.

The TSXP574823A uses a lithium battery to retain program memory. Therefore, you must replace this battery every 2 to 3 years. Use the RS-232 port for PL7 programming software connections. Meanwhile, the RS-485 port handles Modbus communications with remote I/O.

Installation and Compatibility

You can mount this processor in any Premium rack slot. Insert the TSXP574823A into the chosen slot until the backplane locks. Then connect the 24V supply to the rack power terminals. Always back up your program before replacing the lithium battery.

This processor runs all PL7 programs from older TSX series CPUs. It also supports all Premium I/O modules without modification. The TSXP574823A replaces TSXP57482 models with faster execution speed.

Environmental and Safety Data

The TSXP574823A operates from 0°C to +60°C. It withstands 2g vibration per IEC 60068-2-6 testing. The circuit board has no conformal coating. Consequently, you must install this processor in a clean, dry cabinet. Replace the battery immediately when the LED indicates low voltage.
