4 Channel Multifunction Relay Module

Description - With 4-channel input and output control, each channel can be set separately 18 kinds of features to meet the needs of more applications - With power anti-reverse function, and does not damage the wrong power supply module - Support DC 8V-32V wide voltage input - At least 0.1 seconds can be set timing, timing accuracy better than 0.01 seconds - Add automatic power saving feature, users can set up their own; All settings option can automatically save the set of non-volatile content - Signal input terminals X1-X4 allows users to select high or low trigger pulse;     Specification  - Operating voltage: recommended DC 8-32V (limit operating voltage DC 6-40V) - Rated power: static power (when the relay does not pull) less than 0.2W; the maximum power (when the relay is fully pull) is less than 1.8W - Operating temperature: recommended -20 ℃ - 60 ℃ (limit operating temperature range -30 ℃ - 70 ℃) - Load capacity: the maximum load capacity of relay normally open port: DC 0-30V / 10A, AC 0-250V / 10A - The maximum load capacity of relay normally closed port: DC 0-28V / 10A, AC 0-125V / 10A Use restrictions: - Relay service life is full load action 100,000 times, so it is more suitable for use in the high current control occasions of lower on-off frequency, not suitable for use in the fast repeated action occasion; - Pay attention to consider the relay port load margin, pure resistive load needs to stay more than 1 times the margin, ordinary inductive or capacitive load must have more than 3 times margin. Module interface: Module voltage / signal input: there is a 7-wire interface, all interfaces have terminals. 1. DC +: DC power supply positive 2. DC-: DC power supply negative 3. XCOM: photoelectric isolation signal input common end 4. X1: input signal detection interface 1 5. X2: input signal detection interface 2 6. X3: input signal detection interface 3 7. X4: input signal detection interface 4   Download
