OTEK, the innovator and leader of Loop Powered Instruments, brings you another World's First! The LPT (Loop Powered RF Transceiver) is a Patent Pending system that combines the reliable 4-20mA current loop and the wireless technologies. No more wires, conduits, safety barriers and expensive certifications. (read more)

Model TLS 4-20 mA Loop Splitter / Retransmitter splits one 4-20 mA input loop into three independently scalable 4-20 mA output loops. Device removal or failure of any output loop will not affect the other loops. The unit mounts on a DIN rail and is available for 95-265 Vac or 11-30 Vdc power. It can power a 2-wire transmitter at 20 Vdc and drive loads up to 600 ohms at 20 mA. (read more)

Current Sensing Relays provide an effective and highly stable method for monitoring electrical current. Current Transducers and Transmitters are for AC or DC Voltage & Current Voltage, Current, Power, Power Factor, Energy and Frequency can all be monitored in a single package. The sensed information is then provided to the system via an RS485 serial bus. (read more)
