About the product

SFAR-1M-1TI1DO has 1x TI (Temperature Input) and 1x
DO (Digital Output). Temperature Input can work with the most popular temperature sensors: PT100, PT500, PT1000, NI100, KTY81-110. Besides Temperature Input supports also a wide range of thermocouples types: J, K, T, N, S, R, B. Digital Output is NPN type open collector
with maximum load max. 250 mA, 55 V DC. Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O. The use of 32-bit ARM core processor provides fast processing and communication with the baud rate from 2400 to 115200 bps. The module is equipped with a set of LEDs used to indicate the status of inputs, outputs, power supply and RS485 communication. This feature is useful for diagnostic purposes and helping to find errors. Built-in miniUSBallows for initial configuration of the unit without power supply.
