750-439/040-000 WAGO Programmable Logic Controllers

Wago 750-439/040-000 is an I/O unit designed as an intrinsically-safe standard 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 efficient wiring and is built to withstand extended temperature ranges, operating effectively in ambient air temperatures from -40°C to +70°C and storage temperatures from -40°C to +85°C. It supports an IP20 communication protocol and is equipped with short-circuit and wire-break protection mechanisms. The module has a rated insulation voltage of 24mm and is housed in a durable polycarbonate (PC) / Polyamide (PA) 6.6 casing. It includes 8 digital inputs with NAMUR high-side switching and a 2-wire output voltage DC with a 3ms filter for digital inputs voltage ranges. The unit's current consumption includes vibration resistance according to EN 60068-2-6 at 5g and shock resistance according to EN 60068-2-27 at 15g (11ms / half-sine / 1000 shocks) and 25g (6ms / 1000 shocks). It has a resistance of 0.54 W and a display type indicating a secondary current of 56mA (5Vdc, system supply) and 11mA (field supply) with no external load. The module is designed for mounting on a DIN-35 rail and has dimensions of H100mm x W24mm x D67.8mm. It is designed to operate with a 95% relative humidity (RH, non-condensing) environment.
