The IoThing Combo 12 modules are professional modules with two Omron G5Q-14 relays and two analog input channels based on an analog digital converter (ADC) from Texas Instruments (ADS1015).
The relays have a maximum switching current of 3A at a voltage of 250 VAC or 30 VDC. The type of switch is SPDT. Galvanic isolation - individual. An electrical insulation strength of 4 kV VAC (within 1 minute between the coil and the contacts) and 1 kV VAC (within 1 minute between the contacts of the same polarity) is ensured. The relay is controlled via the I2C interface using the PCA9536DP,118.
The IoThing Combo 12 boards allow you to measure two differential analog signals, both voltage and current. The two ADCs installed on the module (ADS1015 from Texas Instruments) are  12 bits . Type of ADC - ΔΣ (delta-sigma). Voltage measurement ranges: 0-0.5V, 0-5V, 0-10V, ± 0.5V, ± 5V, ± 10V. Current measurement ranges: 0-20mA, 4-20mA, ± 20mA, 0-40mA. Measurement speed: up to 3300 measurements per second.
mikroBUS modules can be installed on the IoThing Combo 12 modules, for example, BOKRA SoM Lite or Click® modules from Mikroelekronika.
The IoThing Combo 12 module size 65 x 56 mm. The format of the module corresponds to the popular format of the Raspberry Pi 3A+, which greatly simplifies its use with the Raspberry Pi.
Power supply: 9-36VDC.
