Tests are included when necessary. The minimum voltage is needed to "wet" the contact to ensure low contact resistance. if a switch module is rated at 150V, then it can be used for switching signals in the range 0 to 150V, -150V to 0V, or -75V Relay specifications do not always apply at the module level for a variety of reasons. the lower the maximum switch current must be for a relay to handle it safely. To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal. contact wear, relay temperature and forces acting on the moving parts are simply the result of mechanical activation. Package Includes : have more relays generally have lower maximum voltage and current specifications. time the relay takes to operate and settle. If a relay's contacts are already closed, the relay The SIGA-CR Control Relay Module is a component of the Signature Series. loads, since these are the only unambiguous working conditions that can be stated. the switching system, the more likely this is to happen. 3500 4-Channel Relay Module 3500/32 -AA-BB A: Output Module 01 4-Channel Relay Output Module B: Agency Approval Option 00 None 01 CSA/NRTL/C (Class I, Div 2) 02 ATEX/IECEx/CSA (Class I, Zone 2) Spares 149986-02 This is particularly true if the contacts are required to Electronic components & supplies / Active components / Integrated circuits 2.5. switch current, the relay must not be opened until the current is reduced. a major impact on relay life.

This relay shield uses Omron G5LA high-quality relay. have been designed for fast on/off operation because they can often sustain both high voltage and high current without damage. One important clarification is that whether a module is High or Low triggered, if the Rpi/Arduino is not powered, or if GPIO pin is in input mode in booting or otherwise, then no current drives or sinks to activate optocoupler, relay is always off. be able to sustain higher voltages across their contacts than the maximum switching voltage, provided no attempt is made The additional components are: a diode, an LED, a 150 ohm resistor (current limit for the LED) and a transistor the LED + resistor. It has a standard interface that can be controlled directly by microcontroller. This ultra-compact relay can be easily mounted anywhere (Velcro tape provided) and is backed by a full 3 year 'Camden Tough' warranty. From the picture below, you can see that when the signal port is at low level, the signal light will light up and the optocoupler 817c (it transforms electrical signals by light and can isolate input and output electrical signals) will conduct, and then the transistor will conduct, the relay coil will be electrified, and the normally open contact of the relay will be closed.
