PV and SV Retransmission
PC900 can retransmit measured value or setpoint as a 4-20mA or 0-10V analog signal over the SPL to SPH range, making it easier to connect recorders and synchronized control equipment.
Setpoint Data Transfer
The controller can transmit SV to lower-level instruments through RS485. This is useful for multi-stage or multi-zone systems that need coordinated settings.
Analog Setpoint Input
A second 0-10V analog input can be used as the controller setpoint, with the input range mapped to SPL through SPH.
Print Format
The print function supports fixed record formats for process logging.
Non-Linear Correction
Non-linear correction improves display and control behavior where the sensor or process relationship is not naturally linear.
