753-638 WAGO Programmable Logic Controllers

Wago 753-638 is an I/O unit designed with pluggable 2 x Up/Down counter slice module functionality. It operates on 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 features push-in spring cage-clamp connections for secure and efficient connectivity. It is designed to operate within an ambient air temperature range of -25°C to +55°C and can be stored in temperatures ranging from -25°C to +85°C. The 753-638 supports a control voltage (DC) and utilizes an IP20 communication protocol. It is built for a rated insulation voltage (Ui) of 12 mm and can be mounted on a DIN-35 rail. The unit's dimensions are H100mm x W12mm x D69.8mm, and it is housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing. It features a 500Hz switching frequency and includes 2 x digital inputs for counter operations, supporting 16-bits phase-to-neutral rated voltage (AC). The device is designed to withstand shock resistance according to EN 60068-2-27 at --15g and operates with a minimal resistance of 10mA (5Vdc, system supply) and 8mA (field supply, no external load). It is built to handle 95% relative humidity (RH, non-condensing) for climatic resistance.
