Product Description
The 0G0012.00-090 is an I/O module having twelve digital outputs and designed for 24 VDC 1-wire connections. Modules contain extensive status indicators that display the operational condition, overall module state, and I/O function per channel. For instance, diagnostic possibilities are presented through module run/error indicators and output error status monitoring with LED indicators as well as software. In total, the power consumption of this internal I/O is 1.15 W while that from the bus is at 0.26 W and an additional 0.63 W comes from actuators.
This 0G0012.00-090 product carries approvals by CE, UKCA, ATEX Zone 2 and cULus (E115267) for use in hazardous areas as well as a range of industrial applications. These digital outputs derive their power from current-sourcing FETs, which have a nominal voltage of 24 VDC. They have switching voltage ranges to operate within +/-15% / +20% around their nominal values of ~24VDC. The switching currents on each output should be less than or equal to half an Ampere while they can carry up to six Amperes total current at any given instant in time if necessary.
The output circuit has thermal shutdown protection against short circuits and overcurrent's. Apart from source connections, it likewise has the freewheeling diodes internal to the module enabling it to switch inductive loads. Diagnostic status monitoring is deferred by ten milliseconds (10ms). Leakage current when the output is off is approximately 5 uA with RDS(on) being about 210 m1/2. Peak short-circuit current here does not exceed twelve amperes, whereas switch-on delay during overloads or short-circuits totals about ten ms.
