Specification: Item Type: Remote I/O Controller Description: The network remote I / O controller HF6508 is a controller for remote input (DI), output (DO) control and analog input (AI) acquisition via Ethernet. This section adds the P2P function, which can be used to control remote relays, switch quantity collection, and analog quantity collection through PC or mobile phone P2P software anywhere. Contains 8 channel D1, 8 channel DO, 8 channel AI inputs. Among them, DI supports dry node (switching amount) and wet node (voltage amount), wearing optocoupler isolation; DO is a relay output with 10A 250V or 10A 30V control capability; AI analog quantity can be voltage, such as 0-5V. 0-10V, etc. It can also be a current such as 4-20mA, or it can be a resistive sensor such as a temperature sensor Parameter: Size: L x W x H = Approx. 11.5 x 19.7 x 2.5cm / 4.5 x 7.8 x 1in Upper Layer Protocol: TCP / RTU Low-Level Communication: Ethernet, RS485 Relay Transmission Speed(ie Response Time): <30ms AI Input Form: Current Input: 4-20mA Voltage Input: 0-5V, 0-10V Resistance Input: 0-10K, resistance temperature and humidity sensor, etc. Power Consumption(relay non-sucking state): <124mA at 24V Operating Temperature: -40-85 Storage Temperature: -45-165 Humidity Range: 5-95% relative humidity Package List: 1 x Remote I/O Relay Controller 1 x Serial Wiring Cable
