750-640 WAGO Programmable Logic Controllers

Wago 750-640 is an I/O unit featuring a Real-time clock (RTC) module. It operates with a supply voltage of 5Vdc provided by the system and offers an adjustable supply voltage of 20.4-28.8Vdc to field sensing devices. This unit utilizes push-in spring cage-clamp connections for secure and efficient connectivity. Designed with 32 channels and switch points for on/off operations, it does not require an AC supply voltage, functioning solely on DC. The ambient air temperature suitable for operation ranges from 0°C to +55°C, while for storage, it can withstand temperatures from -25°C to +85°C. The degree of protection is marked as IP20, and it has a rated insulation voltage (Ui) of 12 mm. The unit's dimensions are H100mm x W12mm x D69.8mm, housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing, suitable for mounting on a DIN-35 rail. It features 1 x digital input with digital input voltage ranges from -4 to +1Vdc (OFF) and 3-24Vdc (ON). The primary voltage is designed to resist shocks according to EN 60068-2-27 at --15g, and it operates with a current of 20mA at 5Vdc from the system supply and 11mA from the field supply, without requiring an external load. The unit can operate in environments with up to 95% relative humidity, non-condensing.
