Our UC-CAN modules are stand-alone modules with an open CAN protocol. The UC-CAN-O16 has 16 digital inputs for recording voltage levels from +5V to +50V AC /DC.
- CAN interface with galvanic isolation
- Open CAN protocol
- Automatic send/receive mode
- 16 digital inputs: 15V – 30V AC/DC (optional 5V – 15V or 30V – 50V)
- 16-bit counter per channel (up to 10kHz) with latch function
- Filter for counters / flip-flops adjustable from 5ms – 255ms
- LED status display for each input channel

Digital inputs
With our optocoupler inputs, digital signal states can be recorded within a voltage range of 5V to 30V AC or DC. Input and output circuits are galvanically isolated from each other up to 2.5kV.
Digital In Input Filter
With our Digital-In modules, an input filter can be set in a time interval of 1ms…255ms to filter interference pulses.
This means that AC signals can also be detected cleanly.
Counter
Each input has a 16 bit counter that can count up to 65535 pulses. If the maximum counter value is exceeded, the counting process starts again from zero. By means of a software command, the current status of all input counters can be read from the module simultaneously.
Recording of status changes
Status changes that occur between the readout cycles are reliably detected by internal flip-flops and can be read out separately by software. In addition, such an event is signalled by a status LED. Resetting is done automatically after the flip-flops have been read out.

LEDs
There are a number of status LEDs on the front of the modules. This gives you a quick overview of the most important functions of the modules, such as the switching status of the individual I/Os, module status or whether there is proper communication with the module. This can be very helpful for quick error analysis, especially when used in the field.

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.
