"Extremely Helpful. Shipped me a replacement unit next day and i was up and running within 24 hours. Replacement new from machinery manufacturers was on a 7 day lead time."
The Turck BL20-4DO-24VDC-0.5A-P is a versatile and reliable electronic module designed to enhance the functionality of automated systems. This module features four digital outputs with PNP switching, capable of handling a current of up to 0.5 A per channel. It operates at a nominal 24 VDC from the supply terminal, ensuring compatibility with a wide range of industrial control systems.
Constructed with a focus on durability and performance, the module boasts a compact design with dimensions of 12.6 x 74.1 x 55.4 mm, making it suitable for space-constrained applications. The BL20-4DO-24VDC-0.5A-P is engineered to withstand challenging industrial environments, with an operating temperature range of 0 to +55 °C and storage temperatures from -25 to +85 °C. Its robust build is complemented by a protection class of IP20, safeguarding the module's internal components from dust and other particulate matter.
The module's outputs are designed to handle resistive, inductive, and lamp loads, with specific load resistances for each type. It features short-circuit protection and a simultaneity factor of 1, ensuring reliable operation even in complex circuits. The output delay is a minimal 0.25 ms, allowing for rapid signal processing and control.
For ease of maintenance and enhanced flexibility, the BL20-4DO-24VDC-0.5A-P allows for separation of the connection level from the module electronics. This separation is facilitated by the use of purely passive base modules, which can be chosen with either tension spring or screw connection technology. The electronic modules are completely independent of the higher-level field bus, thanks to the use of gateways, providing a versatile solution for various industrial applications.
The module is equipped with LEDs that indicate status and diagnostics, offering a clear visual representation of the module's performance. Additionally, the electronics are galvanically separated from the field level via optocouplers, ensuring signal integrity and reducing the risk of electrical interference.
With a Mean Time To Failure (MTTF) of 1237 years at 20 °C, as per SN 29500 (Ed. 99), the Turck BL20-4DO-24VDC-0.5A-P is a reliable choice for long-term use in automated systems. It has received CE and cULus approvals, and is suitable for use in zone 2, Class I, Division 2 hazardous locations, demonstrating its compliance with stringent safety and quality standards.
The Turck BL20-4DO-24VDC-0.5A-P is an ideal solution for those seeking a high-quality, dependable electronic module for their automation needs. Its robust design, flexible connectivity options, and reliable performance make it a valuable addition to any industrial control system.

Thumbs up to Rob for helping out with an urgent requirement we had on a Friday afternoon. The part we wanted was over in Europe and Rob went out of his way to get it ordered and on site here for the following Tuesday.City Bearings
Absolutely fantastic service. Rob was very helpful. Great communication. Requested part was shipped in no time.Konrad Eliaszuk
Found the component i was looking for ad a great price. Great support from the staff as I was paying using a wire transfer. - Quick delivery and very good packaging.Adriano Tiberi
Found the part we needed at the best price. Spoke to Rob to make sure the part was actually in stock, as many companies don't actually have the part available to ship. It was in stock ready and the part was checked and shipped and received within a couple of days from their German stock. Would definitely use again and recommend.Chris Sentance
FIRST TIME WORKING WITH MARVO. THEY HAD WHAT I NEEDED AND TOOK GREAT CARE OF ME AND GOT MY ORDER OUT IMMEDITELY. WAS VERY IMPRESSED WITH THE SERVICE AND THE PERSON I SPOKE WITH. I WILL DEFINITELY WORK WITH THEM QGAIN IN THE FUTURE.Robert Cohen
After ordering an urgent part from Marvo i received a great level of customer service and Rob was very helpful.Claire Hinchliff
