SCADA Devices for Analog Signals

SCADA Devices for Analog Signals

GDA8A is a data acquisition module that powers eight 4-20 mA loop power devices, conditions and measures their signal with very high accuracy. It has a RS485 MODBUS RTU port and can be read by a MODBUS master many times a second. The port represents 1/8 of a standard load which allows up to 247 devices to be connected to the same 2 wires of the RS485 network. GDA8A also has an accurate stop watch with a start/stop input. Using it the master can measure duration, time, can log the data collected from the devices or just use this input as a general digital input to monitor a contact closure or some other signal.

Features
  • ALL INPUTS ARE MEASURED 100 TIMES PER SECOND
  • THE MASTER CAN READ ALL DATA UP TO 40 TIMES PER SECOND
  • EACH ANALOG SIGNAL IS MEASURED WITH AN ERROR 0.01% FS TYP.
  • ALL INPUTS HAVE RELIABLE PROTECTION
  • WORKS WITH 7-40 VDC POWER, REVERSE POLARITY AND SURGE PROTECTED
  • STOP WATCH TIME ERROR IS LOWER THAN 1 ms
  • VERY HIGH PROTECTION ON THE RS485 PORT
  • BUILT-IN TERMINATION RESISTOR, JUMPER SELECTABLE
  • MODBUS RTU COMPLIANT
  • HIGH EFFICIENCY, LOW POWER CONSUMPTION
  • SMALL SIZE


Our GpH140 series transmitters offer up to two pH inputs, up to two mV inputs that can be programmed to also accept 11 types of thermocouples, one Pt1000 RTD input and one 4-20 mA input. All with typical error of 0.03% FS and a great flexibility. Always available is also the built-in cold junction compensation with an absolute error of 0.2 oC.


pH + dissolved oxygen transmitter

GpH140-11 has two inputs with an extremely high impedance, specially designed to measure pH and / or REDOX / ORP.

GpH140-12 has one input for pH / REDOX / ORP and one for mV / thermocouples.

GpH140-22 has two inputs for mV / thermocouples.

All of them have as a standard one Pt1000 RTD input, the built-in cold junction compensation and one 4-20 mA two wire loop power input.
