Modbus 4 opto-coupled, 9 relay outputs and 3 temperatures and humidity measurement unit
Dimensions: 145mm x 90mm x 70mm Clickable on a DIN rail General descriptionThe ACC4I9O3TRHMod allows you
The ACC4I9O3TRHMod is Modbus compatible.
The inputsThe inputs are optocoupled, giving the state of a voltage free contact.
The outputsThe outputs are 230V/2A NO one contact relays.
Temperature and humidity measurementThe measurement of temperature and humidity is done with digital sensors communicating with the ACC4I9O3TRHMod. Due to the digital nature of the dialog between the sensor and the ACC4I9O3TRH, the communication is very robust. The precision does not depent on the wires length neither on the connections.
Temperature only measurementIn using temperature sensors, only the temperature information will be available. The measurement of temperature is done with digital sensors communicating with the ACC4I9O3TRHMod. Due to the digital nature of the dialog between the sensor and the ACC4I9O3TRH, the communication is very robust. The precision does not depent on the wires length neither on the connections. Compatible with all our program temperature sensors (based on DS18B20 or on Pt1000).
The sensors are connected to the ACC4I9O3TRHMod on a screw connector.
Modbus Baud rate: 2400 bauds to 19200 bauds. Address 1 to 255 (the adresse 0x3A or 58 is not available, it is the start of message in ascii mode). 2 or 4 wires with or without termination resistor. RTU or ASCII dialog. Recognized commands: command 03 (read register(s)), command 06 (write register), command 16 (write register(s)) Registres allocation for command 03:
Registers allocation for commands 06 and 16:
Power supply: The ACC4I9O3TRHMod is powered by a 8 to 35V DC voltage.
