753-404/000-003 WAGO Programmable Logic Controllers

Wago 753-404/000-003 is an I/O unit designed as a pluggable frequency counter slice module. It operates with 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 wiring. It is designed to work within an ambient air temperature range for operation from 0°C to +55°C and for storage from -25°C to +85°C. The module supports a communication protocol of IP20 and has a rated insulation voltage (Ui) of 12 mm. It is equipped with short-circuit protection for AC control voltage and is designed for mounting on a DIN-35 rail. The dimensions are H100mm x W12mm x D69.8mm, and it is housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing. The module features a 100kHz switching frequency, 1 x digital input (counter, 24Vdc), and 2 x digital outputs (24Vdc / 500mA) with output voltage ranges of -3...+5Vdc (OFF) / 15-30Vdc (ON). It has a power dissipation/losses with vibration resistance according to EN 60068-2-6 -- 4g and shock resistance according to EN 60068-2-27 --15g. The resistance is 70mA (5Vdc, system supply), and it can operate in up to 95% relative humidity (RH, non-condensing).
