2023-01-27

Ericat portable flow calibrator is an accurate and repeatable instrument, which can help you complete flow control and calibration more quickly and easily. With only one Ericat product, the Allen Bradley programmable controller market has eight characteristics.

● Programmable relay and electric operating mechanism: available for. Process Control, Valve Monitoring, Sequencing, On Start and Toggle Switches. As a key component of online fault monitoring.

● Programmable relay, electric operating mechanism (motor is a protective motor with limited service time), programmable relay, valve monitoring, etc. It has the characteristics of simple structure, reliable action, high degree of automation, transparency, and will not damage the product. It is applicable to: close - motor circuit - press SB1 button - end a cycle - the programmable controller starts to work - the trigger is on - the control circuit completes a RC process.

Workflow: The output control of the servo controller is too fast. When the SB1 trigger pulse causes KMB to trigger CMK control pole → RC ground fast firing, that is, the control output is at high level, so as to control the motor to shift to high speed until KMB pulse stops; KMB triggers CM (place) → RC ground to slow down for 30 seconds, that is, the control output is at high level, so as to control the motor to shift load at high speed and drive the ground to slide. At this time, the control motor reverses.

KM2N series of high stability and high precision constant current source, especially in the case of a high-resolution encoder, the constant current source uses ultra-high precision half wave square wave technology. When the measurement signal frequency is not less than 02Hz, the measurement results of high-precision constant current source can be obtained in the entire carrier range.

The current output of all current output points of KM2N series is realized by diffusion pulse width modulation, which can completely meet the compensation of all control currents, and is very suitable for system applications with special requirements for real-time measurement process.

EDB-YD series RS485/232 conversion voltage is completely matched with the I/O port of the single chip microcomputer, and the I/O function of RS485/232 with the single chip microcomputer can be realized without adding external expansion units.

When the instrument panel is working, the WACHIN35 series 2K/50 data acquisition board (A/D conversion) frequency converter can perform digital control on various on-site instruments, PLC, and data acquisition equipment through the serial data line port, and collect the digital signals on the panel through the output port.
