Description _____________________________________

The 115VAC Low-leakage I/O Block (IC66*BBD101) is an intelligent, configurable module that interfaces discrete sensors and actuators
to a communications bus. The block has eight identical 115VAC circuits. Each circuit can be used as either an input or an output.

Features

Block features include:

Selectable input Filter Time from 10ms to 100ms.

Output feedback for monitoring.

Output powerup defaults.

Outputs hold last state or default.

Pulse Testing for outputs.

Bus Switching Module control.
Control power for the block is tapped off the input/output device voltages wired to the terminals. No separate block power supply is
needed.
Each circuit has electronic fusing that shuts down the circuit in 5ms if output current exceeds 30 Amps with the output turned on, or 20
Amps after 2 cycles. The circuit is easily restored by command from a Hand-held Monitor or the CPU.
Block diagnostics include:

Overtemperature

Failed Switch

Open Wire for tristate inputs

Overload Detection and Shutdown

No-load Detection
Fault reporting can be enabled or disabled circuit by circuit.
