I/O module for expanding the modulo 6 automation system
SAUTER expands the modulo 6 system family. A new I/O module called the modu672-IO provides the automation station with universal inputs and outputs for measurement and control with current signals.
The new modu672-IO module complements the modu660-AS and modu680-AS automation stations as well as the modu612-LC IP coupler to extend their scope of functions. It enables actuators to be controlled using standard current signals (0…20 mA or 4…20 mA) or voltage signals (0…10 V), as well as measurement and recording of binary and analogue input variables (current, voltage and resistance). Local operating options complete the main features of the modu672-IO module.
Advantages of 0…20 mA current signals
- Immunity to interference: Current signals (0…20 mA) are less susceptible to electromagnetic interference and voltage losses over long cable runs compared to voltage signals (0…10 V). This makes current signals more reliable in industrial environments with a lot of electrical interference.
- Constant signal strength: The current remains constant along the entire line, while the voltage can drop over long distances due to the resistance in the cables. This means that 0…20 mA signals can be transmitted more accurately and consistently over longer distances.
- Unambiguity of the signal: With current signals (4…20 mA), an interruption in the line (such as a cable break) can be easily detected, as the current then drops to 0 mA, which is interpreted as an error.
- Avoidance of earthing effects: Since current loops, unlike voltage measurements, are not directly connected to earth, there are fewer problems with earthing loops that could lead to measurement errors.
These advantages make 0…20 mA (or 4…20 mA) signals a preferred choice in industrial control and automation applications, especially when it comes to accuracy, reliability and long-distance transmission.
An addition to the SAUTER system family
The SAUTER modulo 6 system generation combines building technology that has been established for many years with the digitalisation of buildings. With the modu672-IO, SAUTER offers a powerful and flexible solution for expanding existing automation systems which meets the requirements of modern HVAC technology.
The modu672-IO is available as of now.
