750-439 WAGO Industrial Automation Components

Wago 750-439 is an I/O unit designed as an intrinsically-safe DC digital input slice module. It operates with a supply voltage of 5Vdc provided by the system and a fixed 24Vdc supply to field sensing devices. This unit features push-in spring cage-clamp connections for secure and straightforward installation. It is designed with an 8.2Vdc sensor supply output and supports an ambient air temperature range for operation from 0°C to +55°C, and for storage from -25°C to +85°C. The module is equipped with IP20 protection and utilizes a communication protocol that ensures compatibility with various systems. It has a rated insulation voltage (Ui) of 24mm and includes short-circuit and wire-break protection features. The module's dimensions are H100mm x W24mm x D67.8mm, and it is housed in a durable polycarbonate (PC) / Polyamide (PA) 6.6 casing. It supports 8 x digital inputs (NAMUR) with high-side switching and has an output voltage for 2-wire connections. The mounting location is designed for DIN-35 rail with a response time that includes a 3ms filter. Digital inputs voltage ranges are ≤ 1.2mA (OFF) and ≥ 2.1Vdc (ON) for digital outputs. The current consumption includes vibration resistance according to EN 60068-2-6 -- 4g and shock resistance according to EN 60068-2-27 --15g. The resistance is rated at 0.54 W, and the display type indicates a current of 56mA (5Vdc system supply) and 11mA (field supply) with no external load. The unit is designed to operate in environments with up to 95% relative humidity (RH), non-condensing.
