High sensitivity transmitter of photocurrent to 4-20 mA current loop.
Transmitter (current amplifier) with output current of 4-20 mA to include photodiodes into an industrial 4-20 mA data bus
maximum photocurrent: 18 nA
Please contact us for further information on this product.
The AMPCON converts a photocurrent into an output current between 4 and 20 mA. The module is designed for integration into 4-20 mA databusses.
The present module works with a high gain factor and converts a photocurrent of 18 nA (adjustable +/-35%) to an output of 20 mA. This means, a current higher than 18 nA will cause saturation.
Other modules with medium gain (AMPCON_MED, up to 2,5 μA) and low gain (AMPCON_LO, up to 250 μA) are available. Alternatively, please refer to the below instruction for changing the gain.
The datasheet for the AMPCON_HI is available in pdf format:
