XMTA-1000 series intelligent PlD regulator

Overview: The OW-XMTA series intermittent or continuous PID regulator can have up to 5 switch outputs, including one dedicated to controlling the input part's resistance, coupling, and disconnection, and the other 4 for switch, control, or programmable dual timers, counters, or programmable intelligent sound and light alarms

◆ Characteristics

Various analog inputs or frequency inputs can also be subjected to square root and small signal cutoff (specified when ordering).

● Triple display of process quantity indication, given value, and control quantity indication.

● PID regulation positive and negative action selection.

● Manual automatic bidirectional undisturbed cutting and manual automatic status indication.

● Process quantity (transmitter with adjustable measurement interval and reverse action) analog output.

Both intermittent and continuous PID regulators can control analog output.

● Set the analog output to 0~10mA or 4~20mA at will.

The action pattern of each positional control point can be set in 8 different ways (such as upper limit alarm, lower limit alarm, absolute value alarm, etc.)

● Output faults such as broken resistance, broken couple, and broken wire.

The automatic adjustment of proportion P, the adjustment of re adjustment time I, and the adjustment of pre adjustment time d are the adjustment methods I.

PID parameter self-tuning or independent self-tuning of P parameter.

● Control upper limit and lower limit output control range can be set separately.

● Power on automatically or manually (manual output value can be preset).

● Manual and automatic status indication and output.

● Simulate output with internal given value (specified when ordering).

● Two or three analog outputs (specify when ordering).

● The first analog output can be set as frequency output mode (full scale is 3~10000Hz).

One switch can be set to selectively monitor the other two switch values, achieving intelligent sound and light alarm function with silencing time (specified when ordering).

The third and fourth set values can be combined to achieve organic control of a relay, simplifying the external wiring or components of the instrument and reducing the occupation of internal hardware resources. If there are different controls for water pumps or sewage pumps (please specify the associated method when ordering).

The 50Hz synchronous bidirectional thyristor zero crossing compensation control algorithm is used to achieve optimized control of each sine wave, avoiding high-order harmonic pollution of the power grid caused by high-power loads.

● Remote switch quantity control set value displacement (SP=SP1 ± P1h or=SP4).

●The intermittent PID regulator instrument can directly control single-phase resistive loads with AC power below 2KW or output 3 sets of synchronous signals triggering bidirectional thyristors below 500A for users with built-in 40A bidirectional thyristors.

8 sets of given values SP1 and P, I, D parameter storage and calling.

The control output of the remote switch quantity control regulator is PID regulation mode or hold state, with bidirectional disturbance free switching.

● Set the given values and PID parameters online without disturbance.

The control input and output of the remote switch quantity control regulator are PID regulation mode or tracking state, with bidirectional disturbance free switching.
