Modbus RTU Module Industrial Data Acquisition and Control Module

Introduction Modbus RTU Module (A) is an industrial standard mixed input and output module, supports 2-ch relay outputs, 2-ch digital inputs, 2-ch analog current outputs, and 2-ch analog current/voltage inputs. Adopts Modbus RTU protocol with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS Features Supports 7V ~ 36V wide voltage power supply, configurable device address (1 ~ 255), multi devices can be cascaded on RS485 bus Supports power isolation and magnetical isolation, enabling power and signal dual isolation for communication, with high reliability and strong anti-interference capability Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & ESD protection Supports passive and active digital input, with bi-directional optocoupler isolation, built-in debouncing algorithm. The relays support digital input linkage control or toggle control Supports 12-bit high-precision acquisition with multiple range input modes, supports single-ended/differential input, supports voltage and current simultaneous acquisition Adopts high-precision resistors and zero-drift high-precision operational amplifier for more accurate data output or acquisition High quality relay, contact rating: ≤10A 250V AC or ≤10A 30V DC Rail-mount PC flame-retardant case design, easy to install and safer to use 3 × LEDs for indicating the MCU status and signal transceiving status Package Content Modbus RTU Module (A) x1 Screwdriver x1 Note: Online Dev Resources and Tutorials to help you easily get started.
