Product description
The YS1700 Programmable Indicator controller is a single-loop controller that can be programmed by the user to suit a variety of applications. It combines Yokogawa Electric's unique high-reliability technology with ease of use and scalability. The basic model is smaller and lighter than the traditional model, helping to save installation space, and is also compatible with various standards such as the CE mark, FM and CSA explosion-proof standards (additional specifications). In addition, compatible forms are available, emphasizing compatibility with traditional models in terms of panel cutting and depth.
Product characteristics
Improved visibility through TFT LCD even in the morning and evening with direct exposure to sunlight
The lower panel surface also ensures good visibility. In addition, you can select and display operation screens such as meter display, trend display, bar display, alert display and event display. Parameter setting is a complete frontal operation.
Modular operation combination programming is compatible with traditional products in addition
In addition to text, we now also support module coupling, which is a graphical programming approach. The user program uses the optional PC configuration software YSS1000.
Large volume programming text method
The program capacity is up to 1000 steps, and the program capacity of the module coupling method is up to 400 modules.
Control and computing capabilities are enhanced practically
Quantity calculations can be performed in 4-byte floating-point (IEEE754) format. It is equipped with more than 100 arithmetic modules such as exponential and logarithmic functions, temperature compensation, and pressure compensation.
Function selection mode (no program)
Common control functions are integrated into function selection modes (single loop control, cascade control, selector control). Various digital input/output (DI/DO) and analog input/output functions can be assigned by parameters.
Use extended I/O
In the basic form (with extended I/O), you can use 8 analog inputs, 4 analog outputs, 10 DI, and 10 DO (14 DI/DO points in total).
Fail-safe function
Dual CPU configurations (primary CPU and display CPU) allow manual operation, even if one CPU is abnormal. In addition, because of the built-in hard manual circuit independent of the digital circuit, the output can continue to run even if the digital circuit, including the CPU, is abnormal. (Not provided if the hard manual (basic specification code -2 ) is not specified.)
Non-volatile memory is used for memory backup
No batteries and backup capacitors are used, so regular maintenance is not required.
Wide operating voltage range, AC/DC shared power supply
AC (100 VAC) and DC (24 VDC)
