Pantech’s Model 831U is an extended version of its Single channel model 821U. In this 831U model, the user gets all the facilities of 821U but in multiples. Model 831U, is a multi-channel Signal Isolator with a dedicated set of input and output per channel. In universal input mode, the user can select any one of the below mentioned inputs, for each of the channel by front keys. The module is an ideal choice when fanning out of process signal is required. All these outputs are isolated from each other, input and power supply. All these outputs are also isolated from each other. This ensures isolation between various subsystems and protects the system from all grounding problems.
The high end programmed microcontroller allows the user to configure all the parameters of the instrument. All the calibrations, fine tuning of the output can be done without opening the instrument. All the types of inputs, acceptable by the instrument are mentioned further. The unique design of the module requires only one single positive barrier at the input from a two-wire transmitter for intrinsic safety and isolates the control room. The cold junction compensation is built in and up scale burn out is provided as standard features for thermocouple input ranges.
