TR202 – Relay (2X SPDT and 4…20mA in/out)
The TR-202 is a compact device used to convert 4…20mA signal (2 wire) of the transmitters in Relay (SPDT). It can be easily configured to control or detection level (Min and Max). The set point adjustment allows two independent outputs are set in a range from 0 to 100%. Both configurations as the process variable are displayed on 3 digit display.
The TR-202 has Fail Safe system providing more security against power failure, wire break , short circuit, overflow and others. From some applications is often used as an electronic pressure switch for alarm minimum and maximum pressure point, for actuation and automatic shutdown of pumps in control level and among other applications.
The TR-202 is cost-effective, and can be a great option for replace complex controllers, as well as applied in all the line of Sitron’s transmitters.
