Notes: 1. The digital inputs can either be used as voltage monitoring inputs (pull-up disabled) or as impedance sensing inputs (pull-up enabled). See section 4 for details. 2. Typical external resistance values for impedance sensing line monitoring applications (pull-up enabled). 3. Individual 0.12 ma current sources per digital input. Can be enabled/disabled per group of 8 digital inputs. 4. Typical differential input impedance at DC. 5. The sensor supply output pins are hardwired linked and connected via a Polyfuse self-resettable PTC to the internal +5 V supply. 6. Software configurable for each output individually, requires firmware v4.80 or higher to be installed. 7. For supporting additional failure relay outputs (de-activate) or redundant amplifier control (activate). 8. 8 priority levels are available for mutually exclusive output assertion, as required for redundant amplifier control. Additionally priority level 0 corresponds to no priority which allows multiple outputs to be asserted simultaneously. 9.
