Key Features
- Converts digital SPI data to industry-standard 4mA–20mA current loop signals with 12-bit resolution for accurate long-distance analog transmission
- Compatible with 7V to 30V loop supply voltage, supporting a wide range of industrial two-wire transmitter power architectures
- Compact mikroBUS add-on board with SPI interface enables rapid prototyping of 4-20mA sensor transmitters on any mikroBUS-compatible development platform
Applications
The MIKROE-1296 4-20mA T Click board is used in industrial process control systems to transmit sensor readings such as temperature, pressure, or flow over two-wire 4-20mA current loops across distances up to several hundred meters. Engineers prototype PLC-compatible analog output modules with this board, connecting it to SPI-capable microcontrollers on any mikroBUS development kit and driving standard 4-20mA instruments or PLCs with 12-bit current resolution. It is also deployed in field instrument prototyping where a 7V to 30V loop-powered transmitter interface is needed without custom analog output circuit design.

Frequently Asked Questions
Over what cable distance can the MIKROE-1296 reliably transmit a 4-20mA signal in an industrial plant environment?
A 4-20mA current loop signal from the MIKROE-1296 can reliably transmit over cable runs of several hundred meters — typically up to 300 meters to 1000 meters depending on cable gauge and loop resistance — because current is independent of line impedance within the 7V to 30V loop supply range. The constant-current output maintains its 12-bit resolution accuracy regardless of cable resistance, which is the primary advantage of 4-20mA loops over voltage-based analog signals in industrial installations.
What SPI clock and data format does the MIKROE-1296 use to set the output current level from a microcontroller?
The MIKROE-1296 uses a standard SPI interface operating at up to several MHz to load a 12-bit digital value into its onboard DAC, which then drives the 4mA to 20mA current output. A 12-bit code of 0 corresponds to 4mA and a full-scale code of 4095 corresponds to 20mA, providing approximately 3.9µA per LSB resolution. The mikroBUS SPI pinout (MISO, MOSI, SCK, CS) maps directly to any compatible host development board without additional level shifters when operating at 3.3V logic.
How does MIKROE-1296 compare to designing a discrete 4-20mA transmitter circuit from scratch for a rapid prototyping project?
The MIKROE-1296 eliminates the need to select, design, and validate a discrete voltage-to-current converter, loop-power regulator, and SPI DAC interface, reducing prototyping time from days to hours. The board integrates a loop supply ranging from 7V to 30V, a 12-bit DAC, and all protection circuitry on a 28.6 mm × 25.4 mm mikroBUS footprint. By contrast, a discrete design requires sourcing a precision V-to-I converter IC, external resistors for current setting, loop-power compliance design, and EMI protection components separately.
