750-403 WAGO Industrial Automation Components

Wago 750-403 is an I/O unit functioning as a standard DC digital input slice module. It operates with a supply voltage of 5Vdc provided by the system and an adjustable supply voltage of 18-32.5Vdc to field sensing devices. This unit features push-in spring cage-clamp connections and is designed for operation in ambient air temperatures ranging from -40°C to +55°C, with storage temperatures from -40°C to +85°C. It supports a control voltage marked as "C" and utilizes an IP20 communication protocol. The rated insulation voltage (Ui) is specified at 12 mm, and it is designed for mounting 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 includes 4 x digital inputs (24Vdc transistor) with high-side switching and supports both 2-wire and 3-wire output voltage (DC). The digital inputs voltage ranges from -3 to +5Vdc (OFF) and 15-30Vdc (ON), with a trip current rating of 7.5mA (5Vdc, system supply). It features a 0.2ms filter for digital inputs, vibration resistance according to EN 60068-2-6 at 4g, and shock resistance according to EN 60068-2-27 at 15g. The unit is designed to withstand 95% relative humidity (RH, non-condensing).
