1TNE968900R0220 is PM564-TP CPU unit of ABB AC500-eCo PLC series with pluggable terminal design. It is high-performance medium-range controller used for medium-size automation system construction and obsolete equipment spare replacement.

1TNE is fixed part prefix for ABB AC500 PLC coding. 968900 refers to base hardware specification of PM564 CPU platform. Suffix R0220 represents factory standard plug-in terminal variant with commercial model PM564-TP.

DC24V operating power supply, 256kB program memory and 128kB data memory. Onboard 8DI /6DO transistor output with single channel 0.5A load capacity. DIN rail mounted, working ambient temperature 0℃~+55℃, storage temperature -25℃~+70℃, IP20 protection for cabinet installation.

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

Execute user programs developed under Control Builder with LD, ST, FBD, SFC programming languages. Realize field signal acquisition, equipment interlock and closed-loop automatic regulation. Transmit operating data and fault logs to upper HMI or DCS via network or serial bus, support SD card program backup and firmware upgrade, maximum expandable total I/O up to 512 points.

Applied for medium-sized wastewater treatment projects, pump and fan group centralized control, automated packaging production lines and HVAC automation systems, cooperating with ABB low voltage components for complete control solution.

Disconnect DC24V power before module removal or wiring modification. Perform quarterly maintenance to clean dust with dry compressed air and check terminal tightness. Regularly back up user program to SD card. Verify communication wiring and field loop firstly before module replacement when communication failure happens.
