Arduino Songle 5v 30a 1 Channel Relay Module

30a relay module, normally open interface maximum load: ac 250 v/30a, dv 30 v/30a optical coupling isolation, driving ability strong, stable performance

The module may have a current of 5ma, high or low level triggered by the jumper (green), relay status indicator light (red). module size: 50mm * 33mm * 24mm. technical parameters: voltage version: 5 v. static current: 5ma. working current: 190ma. trigger current: 2-4ma. module interface features: dc +: dc power source positive pole. dc-: dc power source negative pole. in: signal trigger pin. jd +: relay control voltage positive. jd-: relay control voltage negative. with short jumper cap between dc + and jd +, short jumper cap between dc- and jd-, the same voltage between this trigger terminal and relay control terminal, and selection of high and low level trigger mode. Jumper and l pin connection, trigger in pin is low leveljumper and h pin connection, pin is high level trigger in normally closed pin (nc): relay normally closed pin common pin (com): relay common pin normally open pin (no): relay normally open pin rated current interface is 16a
