753-434 WAGO Programmable Logic Controllers

Wago 753-434 is an I/O unit designed as a pluggable DC digital input slice module. It operates with a supply voltage of 5Vdc provided by the system and a fixed 14Vdc supply to field sensing devices. This unit features push-in spring cage-clamp connections for easy installation. It is designed to work within an ambient air temperature range for operation from -40°C to +55°C and for storage from -40°C to +85°C. The 753-434 supports an IP20 communication protocol and has a rated insulation voltage (Ui) of 12 mm. Its dimensions are H100mm x W12mm x D69mm, and it is housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing, ensuring durability. The unit offers 8 x digital inputs (5Vdc/12Vdc transistor) with high-side switching and an output voltage for 1-wire communication. It is designed for mounting on a DIN-35 rail and features a response time with a 0.2ms filter. Digital inputs voltage ranges from -3 to +5Vdc (OFF) and 2.5-15.4Vdc (ON), with a trip current rating that ensures vibration resistance according to EN 60068-2-6 -- 4g and shock resistance according to EN 60068-2-27 --15g. The unit is also climatically resistant, supporting up to 95% relative humidity (RH, non-condensing).
