The EDA9018A module can be widely used in various industrial control and measurement systems. It can measure PT100, PT500, PT1000. Its output is RS485
Product details
main features
●EDA9018A is measurable: 5Road three line systemPT100 (PT500, PT1000, etc.) input; 1Built in ambient temperature measurement on the road (channel number:)5）The module does not have the function of measuring thermocouple sensors.
●EDA9018A also has:2-channel relay output,(Temperature upper and lower limit alarm, can be set to either alarm or no alarm, alarm value can be set, etc.); Relay output 0 (J0C, J0K) represents the temperature upper limit alarm output, and relay output 1 (J1C, J1K) represents the temperature lower limit alarm output.
●The EDA9018A module can be widely used in various industrial control and measurement systems. It can measure PT100, PT500, PT1000. Its output is RS485 bus mode, supporting three communication protocols: MODBUS-RTU, ASCII code, and hexadecimal LC-04 protocol. The three protocols can be recognized and used simultaneously without configuration;
●Its ASCII instruction set is compatible with modules such as NuDAM and ADAM, and can be hung on the same RS485 bus as control modules from other manufacturers, making it easy for computer programming.
Temperature signal input:
●5 independent temperature signal inputs; Amplify and AD convert the input signal sequence; Signal processing: 16 bit A/D sampling;
●Measurement cycle: 0.15 seconds per channel, digital filtering, 6-channel cyclic measurement.
Relay output:
●Relay output 0 (J0C, J0K) represents the temperature upper limit alarm output, relay output 1 (J1C, J1K) represents the temperature lower limit alarm output, and the output contact capacity is 5A/250VAC; 5A/30VDC；
