Up/Down I/O Module from WAGO

By Editor | July 12, 2012

WAGO Corporation’s 750-633 Ex i Up/Down I/O module records binary signals with NAMUR-Compliant levels within hazardous locations. Part of the WAGO-I/O-SYSTEM, the 750-633 transmits the system’s counter state to a controller or higher-level control system via coupler and fieldbus. The DIN-rail mount 750-633’s modularity makes it ideal for expanding applications, such as supporting machinery within hazardous locations common to oil exploration and processing.

WAGO750-633-Ex-i-Up_Down-I_O-module

750-633’s count direction (up or down) can be adjusted via hardware U/D input (Up/Down). A control byte sets or resets the counting process. The digital output (DO) is enabled via control byte or is activated based on counter value. The maximum counter’s switching frequency is 20kHz. The 24mm-wide module’s status is provided via on-unit 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.
