H0430 temperature transmitter and regulator with RS485 output

Temperature transmitter is designed for two-state control of e.g. heating, ventilation, humidifier, dehumidifier, etc.
Transmitter is equipped with two relay outputs for alarm indication or control of external devices. For each relay setting of delay, hysteresis, audible alarm is enabled.
Measured values are converted to galvanically isolated RS485 serial output.
Transmitter contains built-in temperature sensor.
Degrees Celsius and Fahrenheit are user selectable.
Parameters are easy adjustable from regulator keyboard or from the computer. Large dual line LCD display is an advantage.
Transmitter is also equipped with three binary inputs for detection of two-state events - e.g. water, smoke, glass break detection, door contact.
 

THERMOSTAT APPLICATIONS
- temperature control
- monitoring of temperature and three binary signals at:

• building management and automation
• server rooms
• telecommunication devices
• warehouses, glasshouses
• manufacturers
• museums, archives, galleries
• air-conditioned rooms, HVAC

Serial output RS485 is galvanically isolated from other circuitry to prevent collisions on the RS485 bus. The transmitter works with ModBus RTU communication protocol or with Advantech ADAM compatible protocol. Protocol is user selectable in special configuration mode by means of the PC. Serial link enables to read actual readings and modify transmitter configuration. Instrument works always in slave mode, i.e. responds only to master device query. Transmitters have the address space available from 0 to 255. Communication speed is 110 to 115200Bd.

For acquiring values from several transmitters connected to RS485 bus, third party software is necessary to use.

Tested functionality is with programs:

LabVIEW from National Instruments, TIRS.NET, ControlWeb, EasyView.
