REES52 DC 12V 2-Way Programmable Relay Board/2-Way Voltage Detection Control - RS1859 Micro Controller Board Electronic Hobby Kit

DESCRIPTION Coil Voltage: DC 12V. Two set of conversion (normally open and normally closed). Contact load: 10A/277V AC or 10A/30V DC Contact resistance: ? 100m? (1A 6VDC). Mechanical durability: 10 millions. Electricity durability: > 100,000 (10A-250VAC). Operating Temperature: -40 ~ 85?. Set display shut, the minimum current values are 7mA/12V (delay released). Each group of relay contacts to a common and normally open, normally closed, two sets of conversion. Dual voltage detection control relay, the detection voltage range: DC 0 ~ 99.9V, each channel can be set to detect movement of the voltage on the lower voltage value (DC 0 ~ 99.9V). SPECIFICATION Digital LED display, set by three keys, simple, powerful, has reset function. High-performance microcontrollers, industrial-grade reliability, high process stability, low power, digital display can be automatically turned off , the minimum operating current at 7mA/12V, with reverse power protection , surge current shock. Dual time relay, timer range: 0.1 seconds ~ 9999 minutes adjustable, close/ release cycles is adjustable from 0 to 999 ( “0” means infinite loop ) , timer relays can be set to close first or release first. Dual relay can take turns running, after the end of timer relay A then timer relay B began to run, turn the cycle , can be triggered by high level or switch to start and forced stop (P-3 mode ). Dual relay which can be run independently, can be high or switch to trigger the start (P-4 mode) ; All parameter settings can be saved, the next time modes and parameters continue to the last running.
