Ex i Counter

Wago has developed an Ex i up/down counter (750-633) I/O module for the Wago-I/O-SYSTEM. The counter records binary signals with NAMUR-compliant levels and transmits the system's counter state to a Wago programmable controller or to the higher-level control system via coupler and fieldbus. The count direction (up or down) can be adjusted via U/D input (Up/Down). A control byte sets or resets the counter. The digital output (DO) is enabled via control byte or is activated based on counter state. The maximum counter's switching frequency is 20 kHz. The 24mm wide module's status is provided via LEDs: green for active up/down input, active CLK input (counter input) and activated DO, as well as red for short circuit/wire break of the up/down and CLK signal lines. Field and system levels are electrically isolated and the output is short-circuit-protected. The module's power is provided via separate Ex i 24VDC power supply.
