Ctek I/O Modulesand Options

Over the years Ctek's SkyRouters have demonstrated  interoperability with every major RTU and PLC on the market. Now Ctek has introduced a series of  I/O modules that are fully integrated with the SkyRouter and NetServer application platforms and scaled for real world endpoint requirements.

Ctek's SkyRouter Integrated I/O Modules provide the flexibility required to serve a wide range of analog and digital input requirements, and industrial rated output control to manage everything from indicator lamps to motor start/stop operations.

The 16-port I/O module has 8 open collector digital outputs and 8 high impedance digital/analog inputs. Each output is capable of sinking 350ma of current individually and with all 8 outputs active 250ma of current sink is available on each of the 8 driven outputs. In addition each of the digital outputs can be Pulse Width Modulated (PWM) at 7.8KHz with an 8 bit resolution. Overall, the output capabilities of the 16-port  I/O module provides a generic interface to output devices such as relays, solenoids, strikes, low voltage lamps, and stepper motors.

On the input side the16-port module has 8 inputs that can be configured that can be configured under software control as 5 volt digital inputs or 0 - 5 volt analog inputs. Analog to digital conversion resolution on the analog inputs is 12 bit at a sampling rate of  20Hz. A pulse latching and counting mode of operation detects and counts pulses 3 msec and larger and maintains an onboard count (32767 maximum) of the pulses that can be read under software control. Pulse counting allows the digital inputs to directly interact with a wide range of utility meters including water, electric, and gas metering systems.

For applications requiring a more robust output interface Ctek's relay module has 4 independent SPDT mechanical relay circuits, each under software control. Each relay is capable of handling up to 5 amps at either 30VDC or 250VAC. Switching speed on a relay circuit is 100msec or less. Ctek's relay module is ideal for managing mid range lighting, motor control, and digital signage circuits. 

Ctek Automation Controllers also offer a SPST  15 amp relay for higher current applications. Use this option to switch on pumps, motors, or to perform remote resets on equipment racks.
