750-837 WAGO Programmable Logic Controllers

Wago 750-837 is a Programmable Logic Controller (PLC) CPU unit designed for automation tasks. It operates on a supply voltage of 18-31.2Vdc via wiring with a nominal 24Vdc and can be connected through a 5-pin male connector for fieldbus, a 2-pin cage-clamp for the system, and a 6-pin cage-clamp for the field. This unit does not operate on AC supply voltage and is designed to function within an ambient air temperature range of 0°C to +55°C for operation and can be stored in temperatures ranging from -25°C to +85°C. It supports a communication speed of 10kbit/s to 1Mbit/s and utilizes the CANopen communication protocol. The unit's dimensions are H100mm x W50.5mm x D71.1mm, and it is housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing suitable for DIN-35 rail mounting. It features 64 connections per node and 110 in fieldbus mode on the controller (master), with an 8kB non-volatile memory for software, 128kB for program memory, 64kB for data memory, and 512bytes for fieldbus input and output memory. The unit is vibration resistant according to EN 60068-2-6 at 4g and shock-resistant according to EN 60068-2-27 at 15g. It has a control circuit rated current of 500mA at 24Vdc nominal load, 350mA at 5Vdc system supply, and 1650mA system supply. The 750-837 supports various programming languages including Instruction List (IL), Ladder Diagram (LD), Function Block Diagram (FBD), Continuous Function Chart (CFC), Structured Text (ST), and Sequential Function Chart (SFC), with a programming environment based on WAGO-I/O-PRO V2.3 (CODESYS V2.3) and configuration options through EDS device description file and WAGO-I/O-CHECK. It operates efficiently in environments with up to 95% relative humidity, non-condensing, and is powered by a 16-bit processor.
