Function: SDSS-FEX-4A is mainly used for the output control of frequency converter, which can process analog signals, such as 0 ~ 10V/5V voltage signals or 0/4 ~ 20mA current signals.
Connection mode:
Impedance matching: Select the PLC output module according to the input impedance of the inverter to achieve impedance matching between the two.
Voltage range: When the voltage signal range of the inverter and PLC is different, appropriate measures need to be taken, such as series resistance for voltage division, to ensure that the two work within the normal voltage range.
Shielding measures: In order to prevent the weak current control signal from interference by external strong signals, it is recommended to use shielded cables or stranded cables.
Versatility: The CMA198 module supports many types of input and output signals, such as analog signals, digital signals, switching signals, etc., and can adapt to different application requirements.
Signal processing: The module can process and convert input signals, such as converting analog signals to digital signals, or filtering, amplifying and other operations to ensure data accuracy and stability.
Data acquisition: The CMA198 module can collect data of sensor signals in real time and transmit it to the control system or monitoring system in order to monitor the status of industrial processes in real time.
Control function: In addition to data acquisition, the module can also be used to control the actuator and perform corresponding actions according to preset logic conditions and control algorithms, such as adjusting valves, adjusting motor speed, etc.
Communication interface: The CMA198 module is equipped with various communication interfaces, such as Modbus, Ethernet, etc., to achieve data exchange and communication with other devices or systems.
Transmission speed: 9.6-12,000 kbit/s is supported, but 31.25 and 45.45 kbit/s is not supported. The default transmission rate is 1.5 Mbit/s.
Redundancy: Supports line redundancy and module redundancy.
Hot swap: Supports hot swap and can be replaced without interrupting CEX communication. Hot remove and reinsert automatically configs hardware information.
Usage scenario: Can be used with HI controllers and supports connection to remote I/O and fieldbus meters via PROFIBUS DP.
Power supply: 24 V.
Environmental adaptability: Operating temperature 55 degrees Celsius, protection level IP20 (according to EN60529, IEC 529).
Compliance: Compliance with RoHS compliance Directive 2011/65/EU (en 5081:2012) and WEEE compliance Directive 2012/19/EU.
Program processing time – Block copy time: Digital output (A) : Basic run time 33µs+5µs per set of outputs (A) +30µs Analog output via CS31 bus (AW) : Basic run time 20… 32µs+6µs AW per group.
Function: This module is usually used in gas turbine control systems to monitor, protect and control the operating status and performance of gas turbines.
