The Turck BL20-4DI-24VDC-P is a high-performance electronic module designed to provide reliable digital input capabilities for industrial automation systems. This module features four digital inputs with PNP switching, making it suitable for a wide range of applications that require precise and efficient signal processing.
Operating at a nominal voltage of 24 VDC, the BL20-4DI-24VDC-P ensures stable performance with a low power dissipation of approximately 1 W. The module is engineered to handle signal voltages ranging from -30 to +5 V for low-level signals and 15 to 30 V for high-level signals, with corresponding current levels of 0 to 1.5 mA and 2 to 10 mA, respectively. The input delay is less than 0.2 milliseconds, ensuring rapid response times for critical operations.
The BL20-4DI-24VDC-P is designed with robust electrical isolation to protect the electronics from field-level interferences. It offers flexible connectivity options, including screw and tension spring connections, to accommodate various installation preferences. The module's compact dimensions of 12.6 x 74.1 x 55.4 mm allow for easy integration into existing systems without occupying excessive space.
Certified to meet CE and cULus standards, the BL20-4DI-24VDC-P is suitable for use in Zone 2 and Class I, Division 2 hazardous locations, ensuring compliance with stringent safety regulations. The module operates within a temperature range of 0 to +55 °C and can be stored at temperatures between -25 and +85 °C. It also withstands relative humidity levels of 15 to 95%, provided there is no condensation.
The BL20-4DI-24VDC-P is part of Turck's BL20 series, known for its modular design that simplifies maintenance and enhances system flexibility. By separating the connection level from the module electronics, the BL20 series allows for easy replacement and upgrades without disrupting the overall system. This module is compatible with various base modules, offering a choice between tension spring and screw connection technologies.
Ideal for industrial environments, the Turck BL20-4DI-24VDC-P provides reliable digital input functionality, ensuring efficient and accurate data acquisition for automation systems.

| Functional Principle | BL20 electronic modules are plugged into passive base modules for field device connection. Maintenance is simplified due to the separation of the connection level from the module electronics. The base modules offer a choice of tension spring or screw connection technology. The electronic modules are independent of the higher-level field bus type through the use of gateways. |
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
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.Sean Conlin
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
