- USB 2.0 interface with up to 480 Mbit
- 16 * A/D inputs with 16-bit resolution each
- voltage ranges: 0-5V, 0-10V, +5V, +10V
- Current ranges optional: 0-20mA, 4-20mA, 0-24mA
- 4 * D/A outputs with 16-bit resolution each
- voltage ranges: 0-5V, 0-10V, +5V, +10V
Analogue inputs
Analog to digital converter modules are suitable for measuring and monitoring voltages and currents. Measuring transducers, for example, convert physical quantities such as pressure, temperature, humidity etc. into corresponding currents (0..24mA) or voltages (0..10V) and can thus be recorded and digitally processed with our A/D modules.
Analogue outputs
With our digital to analog converter modules you are able to control current or voltage controlled actuators such as valves, servomotors or special power supplies. Especially in harsh industrial environments and with very long cable runs, analog signals, especially currents, can be transmitted interference-free.
Fail-safe mode
The fail-safe mode is a safety function in which the DEDITEC module switches to a previously configured, safe switching state in the event of a connection failure.
This is intended to prevent connected installations or systems from continuing to run in an uncontrolled manner.
Three switching states can be defined for each digital output: a) Switched off, b) Switched on or c) Unchanged.
The fail-safe circuit is triggered by a timeout protection function. If the control unit no longer receives any commands from the control PC within a previously defined period of time, the timeout function comes into effect. The cause of a timeout can be a loss of connection between the control PC and the DEDITEC control system or failure of the control PC.
Timeout modes
Three timeout modes are available:
A) “Normal mode” is valid once and must be reactivated manually by software command after each timeout event. The customer application still has access to all controller outputs.
B) In “Auto reactivate mode”, the timeout function is automatically reactivated after communication with the control PC has been re-established. The customer application still has access to all outputs of the control unit.
C) The “Secure outputs mode” blocks access to the outputs after the timeout event. Unlocking can only be carried out by software command. This is an important safety aspect
LEDs
Each digital input and output has a separate LED that lights up when the signal state is active. Furthermore, the status of the operating voltage, the communication with the interface, error events or the occurrence of a timeout can be displayed.
Connectors
A screwless system from the manufacturer WAGO Kontakttechnik is used as the connector. The 1-wire female connectors are 100% protected against mismating and have an eject and locking mechanism. All conductor types up to 1.5mm² can be connected.
