EM-M41 is an optical isolator designed for 4...20 mA input signal isolation of PLCs and control systems. Unit provides high isolation voltage. EM-M41 accuracy is sufficient for use in 12-bit applications and supply range is wide. Unit acquires its operating energy from the current loop. Input stage is protected against over current and output stage is protected against over voltage and incorrect polarity. Unit is packed in a rail-mountable housing and is available in 2-channel version as well. With 2-channel model the need for space is only 10mm/channel. The type code for 2-channel model is EM-M41-2.
