Input/output signal

6         Analog Input (AI)

IN1，IN2 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.

IN3 is a feedforward control 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

IN6 is redundant tracking input terminal, can receive 0 ~ 10mA / 4 ~ 20mA / 0 ~ 5V / 1 ~ 5V standard signals

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.

4         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. ,
