Description

Product Introduction

1TNE968900R1210 is PM573-R CPU unit under ABB AC500-eCo PLC series with fixed relay terminal design and integrated onboard analog plus digital I/O. It is a high-spec compact controller for medium-sized automated equipment, applied in cabinet assembly and obsolete automation system spare replacement.

Model Definition

1TNE is fixed part number prefix for ABB AC500 PLC range. 968900 represents core hardware platform of PM573 CPU. Suffix R1210 stands for factory fixed relay terminal configuration, commercial model name PM573-R.

Technical Specifications

Power supply DC24V, program memory 512kB, data memory 256kB. Onboard I/O consists of 6 digital inputs, 6 relay outputs rated max 2A per channel, 2 analog inputs and 1 analog output. DIN rail mounting, operating ambient temperature 0℃~+55℃, storage temperature -25℃~+70℃, IP20 protection grade for cabinet installation.

Interface and Communication Configuration

One built-in 10/100Mbps Ethernet port and one RS485 serial port supporting Modbus RTU, CS31 and ASCII protocols. Two expansion slots for optional communication modules, expandable with S500/S500-eCo remote I/O modules.

Core Functions

Run user programs based on IEC61131-3 standards including LD, ST, FBD, SFC via Control Builder software. Collect field analog and discrete signals to realize equipment interlock, sequential control and PID closed-loop control. Transmit operating data and fault records to upper HMI or DCS through Ethernet or serial bus, support SD card program backup and offline firmware upgrade, maximum expandable total I/O up to 1024 points.

Application Scenarios

Suitable for medium-sized wastewater treatment units, centralized pump and fan control, packaging production lines and HVAC automation systems, matched with ABB low voltage devices to build complete compact control cabinet solutions.

Operation and Maintenance Instructions

Cut off DC24V power supply before module disassembly or wiring modification. Perform quarterly maintenance to remove dust with dry compressed air and check terminal fastening regularly. Back up user program into SD card periodically. Check communication cables and field sensor loops before replacing the module when communication or analog signal abnormality appears.
