750-889 WAGO Industrial Automation Components

Wago 750-889 is a Programmable Logic Controller (PLC) CPU unit featuring a 32-bit processor and supports various protocols including HTTP, BootP, DHCP, DNS, AutoIP, SNTP, FTP, SNMP V3, and SMTP. It operates on a supply voltage of 18-31.2Vdc via wiring with a nominal 24Vdc and can connect through 2 x RJ45 connectors for fieldbus, a cage-clamp 2-pin for the system, and a cage-clamp 6-pin for the field. This unit does not require an AC supply voltage and is designed to operate within an ambient air temperature range of C...+55°C and can be stored in temperatures ranging from C...+85°C. It offers communication speeds of 10Mbit/s and 100Mbit/s, supports Modbus TCP, Ethernet, and KNXnet/IP protocols within an IP20 degree of protection. The net width of the unit is 61.5 mm, and it is housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing suitable for DIN-35 rail mounting. The unit's dimensions are H100mm x W61.5mm x D71.9mm, and it can manage up to 250 connections per node and 64 field devices. It features 32kB of non-volatile memory for software, 1024kB for program memory, 1024kB for data memory, and 512bytes for fieldbus input and output memory. The CPU unit is vibration resistant up to 4g and shock-resistant up to 15g according to EN 60068 standards. It has a primary voltage requirement of 500mA at 24Vdc nominal load, 450mA at 5Vdc for system supply, and 1700mA for system supply. The control circuit's rated current supports various programming languages and environments, including Instruction List (IL), Ladder Diagram (LD), Function Block Diagram (FBD), Continuous Function Chart (CFC), Structured Text (ST), Sequential Function Chart (SFC), with WAGO-I/O-PRO V2.3 and WAGO-I/O-CHECK for configuration. It can operate in up to 95% relative humidity (non-condensing) and includes an SD and SDHC card slot supporting up to 32GB.
