RMC-T300 - 4 Thermocouple Inputs, 4 Relay and 4 PWM Output ModBus RTU Module
Haidar's  RMC-T300 is 4-ch thermocouple inputs ,4-ch PWM outputs and 4-ch relay output ModBus module. Different from other modules, RMC-T300 is not only used to monitor a process temperatures but also can be used to control the process temperatures and up to 4 zones or loops. Three types of control modes: P, ON/OFF and Manual, accepts 7 types of thermocouples, 4-ch PWM or general purpose digital outputs and 4 general purpose relays. Moreover, the user can read the status of the termocouples (open, shorts), relays and digital outputs from the on board LEDs. Built-in full-duplex RS485 ModBus RTU or ModBus TCP interface.
