Isolated Type 16 Channel Relay Module Interface Board HighLow Level Trigger (DC 24V)

Isolation Type 16 Channel Relay Module can select highlevel or lowlevel signal triggering, and only needs 5mA current to drive the relay with 10A control capability to pull in. The module adopts genuine highquality power relay, highquality smallsized package optocoupler, highpower high dielectric strength triode, red and blue signal indicator, militarygrade doublesided PCB board, and with reasonable layout and stable performance, can be widely used in a variety pf powers control. Features: 1. With power supply reverse connection function to prevent damaging the module. 3. Using smallsized twoway isolated optocoupler, with strong antiinterference ability and stable performance; trigger current is only 5mA. 4. Users can select the control level of the relay, which can be high level pullin or low level pullin. 5. The module has builtin finite current resistor. The positive and negative pole control of the power supply can be used directly, or use the IO port of the singlechip to control. 6. Power indicator (red), relay status indicator (blue) 7. Userfriendly interface design, all interfaces can be directly connected by the wiring terminals, very convenient. 8. Designed with 4 3mm fixed bolt holes for easy mounting. Specification: Trigger current: 5mA Mounting hole diameter: 3mm Module size (L*W*H): 15.3*10*2.0cm 6.0*3.9*0.8in Package weight: Approx. 246g8.7oz Module interface: Module control interfaces have 16 wiring terminals. 2. DC: Connect to DC power supply 3. XM: Common terminal of optoelectronic isolation chip If use high level control: This interface should be connected to the negative pole of control board power supply. If use low level control: This interface should be connected to the positive pole of control board power supply. 4. X1X16: Relay control interface Relay output interfaces have 48 wiring terminals. 1. NO1NO16: Normally open interfaces of the relays 2, COM1COM16: Common interface of the relays 3. NC1NC16: Normally closed interfaces of the relays Package l ist: 1 * 16 Channel Relay Module .With power supply reverse connection function to prevent damaging the module.
