Input/output signal

5         Analog Input (AI)

IN1 is  measurement feedback input terminal of the process parameter ,can receive a variety of thermal resistance, thermocouple, standard signals ,either an input signal. a variety of input signals can be switched between the sub-degree numbers, which is based instant.

IN2 is a feedforward control input terminal(XMRA6000) or auxiliary input terminal(XMRA5000), can receive a variety of thermal resistance, thermocouple, standard signals ,either an input signal, a variety of input signals can be switched between the sub-degree numbers, which is based Ready.

IN3 is the valve position feedback signal input terminal, can receive 0 ~ 10mA / 4 ~ 20mA / 0 ~ 5V / 1 ~ 5V either a standard signal such as the various buttons to switch between the input signal.

IN4 is foreign  given (RSP) signal input terminal, accept 0 ~ 10mA / 4 ~ 20mA / 0 ~ 5V / 1 ~ 5V, etc. any standard signal can be switched between a variety of input signal, which is based instant.

IN5 is redundant tracking input terminal, can receive 0 ~ 10mA / 4 ~ 20mA / 0 ~ 5V / 1 ~ 5V standard signals such as any one of the above can be key to switch between the input signal, which is based instant. IN5 is used to receive as the main controller circuit 100 Special Industrial XMRA5000/6000 hot standby redundant controllers, or PLC / DCS control, industrial machines and other equipment of the loop controller output signal (AO), and DI2 (redundant switch input signal) with the realization of hot standby redundancy control. When DI2 = ON, the control output tracking IN5. When DI1 = OFF when the PID control output by the machine operator decision has nothing to do with IN5.

2         Analog Output (AO)

OUT is adjusting control output, 0 ~ 10mA / 4 ~ 20mA / 0 ~ 5V / 1 ~ 5V output ,optional.

OUT1 is the valve-position transmission output terminal ( opening valve position signal), 0 ~ 10mA / 4 ~ 20mA / 0 ~ 5V / 1 ~ 5V output optional.

2         Switch input(DI)

DI1 used ( XMRA5000/6000) as a regulator  for receiving back-up manual manipulator state signal, and analog input IN3 to achieve back-up operation with the device's hand automatically bumpless switching.

DI2 is redundant switching command input terminal, for receiving as the main controller 100 Special Industrial Loop XMRA5000/6000 hot standby redundant controllers, or PLC / DCS control, industrial machines and other equipment fault status signals. To achieve hot standby redundancy state, and local control bumpless switching.

3         Relay input(DO)

DO1 for PV alarm output, its upper and lower limits can be set to alarm mode, the relay output contact closure.
DO2 output terminal of the machine fault condition, in normal work, the relay output contact closure; when the machine fails, the relay output contacts disconnect.

DO3 is the Control Hand / Auto status output, when the machine is in manual state, the relays are movements, the output contact closure. ,
