IC660BBD110  115VAC 16-Circuit Discrete Input Block

Compatibility

The 115VAC Discrete Input Block (lC66*BBD110) is an intelligent,configurable module that provides an interface to 115VAC discreteinput sensors. The block has sixteen 115VAC circuits – two banks ofeight circuits each.
Typical inputs to this block are contact closures from switches,pushbuttons, or limit switches. The block can be used with both 2-wire and 3-wire proximity switch inputs. Control power for the blockcomes from the power line that supplies the inputs. No separateblock power supply is needed.

Features

Block features include:

Selectable thresholds

Advanced diagnostics

Software Configurable Features

The 16 Circuit 115 VAC Input Block provides configurable detection of Open Wire and Shorted Wire faults. Selectable thresholds extend the use of Open Wire and/or Shorted Wire diagnostics to circuits with many types of input devices and sensors.

There are separate On/Off thresholds for each group of eight inputs. On/Off thresholds are configurable from 25% to 85% of the incoming line voltage, allowing the use of a wide variety of input sensors.

Optional Open Wire detection can be selected for individual inputs. The Open/Off threshold can also be configured at 25% to 85% of the incoming line voltage. Separate Open/Off thresholds can be selected for each group of eight inputs.

Optional Short Circuit detection at 10% and 90% of the incoming line voltage can also be selected for individual inputs.
For most applications, the default thresholds and recommended resistor values are not changed.
Fault reporting can also be enabled or disabled circuit-by circuit.
