ABB 3BSE008508R1 DI810

3BSE008508R1 DI8 has 16 digital inputs. The input voltage range is 18 to 30 volts d.c., and the input current is 6 mA at 24 V. The inputs are divided into two individually isolated groups with eight channels and one voltage supervision input in each group. Every input channel consists of current limiting components, EMC protection components, an input state indication LED and an optical isolation barrier. The process voltage supervision input gives channel error signals if the voltage disappears. The error signal can be read via the ModuleBus.

Core Functions and Signal Acquisition Capabilities

Digital Signal Acquisition: Focused on receiving dry or wet contact digital signals from external devices (such as switch on/off status, valve start/stop status, etc.), supporting 8 independent digital input channels, each capable of independently monitoring signal status, meeting the needs of parallel monitoring of multiple devices.

Wide Voltage Adaptability: Input signals are compatible with multiple voltage ranges, mainstream support for 24V DC (common industrial standard), and adaptable to 12V DC or 48V DC in some scenarios (specific requirements depend on system configuration). It can interface with digital output signals from different types of sensors or actuators.

High-Speed ​​Response and Filtering: Possesses fast signal response capabilities, with typical response times in the millisecond range (specific times may vary slightly depending on signal type). It also supports software-configurable digital filtering functions, effectively suppressing electromagnetic interference and impulse noise in industrial environments, ensuring the accuracy of signal acquisition.
