Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

In chemical plants and refineries, engineers rely on the WAGO 750-439 to safely acquire signals from NAMUR sensors in hazardous areas. This 8-channel digital input module is intrinsically safe (Ex i), allowing direct connection to proximity switches and contacts in Zone 0/1 or 2/22 without external isolators. Its CAGE CLAMP® spring pressure connection technology ensures vibration-proof, maintenance-free wiring, while per-channel LEDs provide immediate status indication. The module integrates seamlessly into WAGO 750/753 fieldbus nodes via DIN-rail mounting, delivering robust performance for demanding process automation.

Key specifications

  • 8 digital inputs for NAMUR sensors (EN 60947-5-6)
  • Intrinsic safety: II 2 G Ex ia IIC T4 Gb, II 2 D Ex ib IIIC T135°C Db
  • Sensor supply: 8.2 VDC internal; input current ON >2.1 mA, OFF <1.2 mA
  • Fault detection: wire break (<0.15 mA), short circuit (>6.5 mA)
  • Channel-to-channel and channel-to-system isolation
  • Operating temperature: -20 to +60 °C
  • Per-channel green/red status LEDs
  • Input delay: typ. 3 ms
  • Protection: IP20, DIN-rail (TS 35) mounting

Why choose it

This module simplifies hazardous area wiring by providing intrinsic safety barriers directly at the I/O level, eliminating the need for external isolators. Its CAGE CLAMP® spring pressure connection technology ensures vibration-proof, maintenance-free wiring, while the per-channel LEDs offer immediate status indication for commissioning and troubleshooting.

Ideal use cases

  • Monitoring valve positions, level switches, or proximity sensors in chemical plants
  • Interfacing with NAMUR sensors in pharmaceutical manufacturing
  • Signal acquisition in oil and gas facilities with hazardous areas

Good to know

The module supports 2- or 3-wire NAMUR sensors and provides channel-to-channel, channel-to-system, and channel-to-supply isolation for enhanced safety and reliability. It consumes typically 100 mA from the 24V system supply and is designed for DIN-rail mounting in control cabinets.
