The BOKRA I2C 2RO+2DI Pro modules are professional digital I/O modules with two Omron G5Q-14 relays and two digital input channels (based on Texas Instruments ISO1211).
Rated resistive load: 3A at a voltage of 250 VAC or 30 VDC. Contact form - SPDT. The galvanic isolation is individual. The dielectric strength of the insulation is 4 kV AC (for one minute between the coil and the contacts) and 1 kV AC (for one minute between the contacts of the same polarity).
The modules allow you to enter the values of two digital signals, both DC and AC. Supports 9-V to 300-V DC and AC Digital Input. Compliant to IEC 61131-2; Type 1, 2, 3 Characteristics for 24-V Isolated Digital Inputs. Accurate Current Limit for Low-Power Dissipation: – 2.2 mA to 2.47 mA for Type 3. Maximum transient isolation voltage (up to 60 s) – 3600V.
The BOKRA I2C 2RO+2DO Pro module is controlled via the I2C interface using the MCP23008 chip.
MikroBUS modules can be installed on the BOKRA I2C 2RO+2AI Pro modules, for example, BOKRA SoM Lite or Click® modules from Mikroelekronika.
The BOKRA I2C 2RO+2AI Pro 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.
