Modules of remote input/output

Radio connection to DI-DO CILK-RF446-DI-DO


Radio module is designed for organization of the condition transfer of discrete inputs and data through the radio connection at the distance up to 500 meters in the unlicensed range of frequency 446 MHz.

Variant of radio connection module for transfer the condition of DI (DI repeater).
In this mode the set of two devices is used which are tuned to each other for data transfer through the radio channel. The sensor of the type “dry contact” or active signal with the output to the alternate current under the voltage up to 200 Volt are connected to the discrete inputs, to the discrete outputs - actuation device. When the sensor operates at one device the appropriate discrete output on the paired device is switched on and vice verse. The functional scheme of this mode of operation is shown underneath.

Variants of operation in the mode of data transfer

In this mode the module works as a radio modem for data transfer from the radio connection of telemechanics, getting the information about the condition of discrete inputs and the control of discrete inputs. The protocol of data transfer through the radio channel is RTM/RTMVar, through the COM port is RTM/RTMVar or MODBUS.

Additional opportunities 

Radio module has the opportunity of line supply 220 V or from the source with the voltage of 12 V. There is a built-in accumulator for operation when the supply voltage is lost. Operation time of the built-in accumulator is up to 15 minutes.

Series of remote input/output modules CILK PAC IO

Modules of remote input/output allow to work with the signals of discrete and analog input/output through RS-485 interface on the protocol Modbus/RTU. To one controller CILK PAC with regard to inner plates of expansion and outer modules can be connected: discrete inputs – 1024, discrete outputs – 1024, analog inputs – 1024, analog outputs – 1024. The size of address space with the access to the protocols of data transfer – 125 kilo addresses. Quick installation and module change without disconnexion of the group of devices is made due to connector HBUS or 2-wire type interface.
Variative set of modules of remote input/output has scales according to demands: from 8 up to 48 DI for module; from 4 to 16 Al for module; from 4 to 16 AO for module; from 4 to 16 DO for module.
