1TNE968900R0200 is PM564-T main CPU module belonging to ABB AC500-eCo PLC series with fixed screw terminal structure. It is high-performance upgraded model of PM554 series, designed for medium-size automated control systems, widely used for cabinet assembly and obsolete automation equipment spare replacement.

1TNE is unified part number prefix for ABB AC500 series PLC coding standard. 968900 represents base hardware specification of PM564-T CPU. Suffix R0200 stands for factory standard fixed terminal version, official trade name PM564-T.

Operating power supply DC24V. Program memory 256kB, data memory 128kB. Onboard 8-channel digital input and 6-channel transistor digital output with per channel 0.5A rated load. DIN rail installation, working ambient temperature 0℃~+55℃, storage temperature -25℃~+70℃, cabinet inner protection grade IP20.

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

Process user programs programmed by LD, ST, FBD, SFC languages via Control Builder software. Collect field discrete signals to realize equipment interlock, timing and closed-loop regulation control. Upload runtime data and fault records to upper HMI or DCS via Ethernet or serial bus, support SD card program backup and offline firmware upgrade, maximum expandable total I/O up to 512 points.

Suitable for medium-sized water treatment plants, complete pump and fan cluster control, packaging production lines, HVAC system and small process automation projects, matched with ABB low voltage electric components to build full set control solution.

Cut off DC24V power supply before module dismounting or wiring adjustment. Implement quarterly maintenance to clear module and terminal dust with dry compressed air and inspect terminal tightness regularly. Back up control program to SD card periodically. Check bus cable and field circuit firstly instead of direct replacement once communication error occurs.
