◆ size valve control, alternating with two barrels of control
◆ pulse input or analog input
◆ DI Channel 4, DO Channel 3, configuration
◆ temperature compensation, and 10 of the broken line compensation
◆ control accuracy: ± 1digit
◆ Modbus communication I (photoelectric isolation) optional

● two bulk control.
● pendulum control, with a barrel for the turn. On the relay, electromagnetic valve delay dynamic correction, quantitative increase accuracy.
● a fluid automatic temperature compensation.
● there (9) broken line of Correction, to the sensor, the transmitter of the non-linear automatic error correction.
● band for 24 V DC and 12 V DC power supply (a short-circuit protection) to simplify the system, saving investment.
● rich self-diagnostic features that make instruments easier to use and maintain.
● passwords to prevent unauthorized personnel change has been set of data.
● any instrument with no internal potential, such as adjustable switch coding devices, thereby enhancing the instrument's vibration-resistant and reliability.
● specially designed WDT circuit, a power-on reset circuit, to ensure the normal operation of electricity meters, the data after power is not lost.
● power back-up batteries do not have data protection, the protection of the time 10.
● communication with the host computer.
● Metal Case ensure good electromagnetic shielding.
