MultiCon multichannel controllers and recorders are clearly the right choice for multi-point measurement systems.

The support for simultaneous monitoring of various parameters is not limited just to physical integrated inputs. MultiCon is also capable of reading measurement signals in a Modbus network through an integrated RS-485 interface so that it can be used in systems with considerable distances between the subsequent measurement points.

The following model works well in the example application: CMC-141-PS42/ACM/UN5/UN5/UN5-0B1

Signal inputs:

Each UN5 module consists of 5 isolated universal inputs (U/I/RTD/TC/mV). Ten of the available inputs read measurements from temperature sensors whereas the other five from AO transmitters.


The ACM module is equipped with RS-485, RS-485/232, USB and Ethernet ports, providing many options for real-time communication with the device. For instance, the RS-485 interface ensures connection to the Modbus network for on-line measurements transfer, whereas the Ethernet port enables connection to a corporate network to provide a continuous remote preview of the recorded data.


The device is designed for recording values both from 15 integrated inputs and 45 other values read from a serial communication network. It, therefore, utilizes its full potential by recording data from 60 measurement channels at the same time.

Special features:

For ease of use the USB port is located on the front panel of the device.
