Designed for wireless data logging and wireless on-off control for any variable converted to V/mADC, this addition to Otek's wireless product line offers eight 4-20mA inputs/outputs and alarms. The model TR550 transmitter can be used as stand-alone wired data logger or as a serial link (RS232/485) with a selectable baud rate from 1200 to 19.2KB, 8N1. Since the transmitter has its own offset and scale controls, the data can be sent serially in engineering units format, i.e., pressure in psi, voltage in volts, etc.
Features include multiple transmitters and receivers (255 addresses), serial data of each channel, on demand or polling. Hi/Lo limits are programmable for each channel.
