IC660BBD023 IC693MDL654 DC 16 circuit source block

Description

A DC 16-Circuit Source/Sink I/O Block is an intelligent, configurable
block that can interface to a wide range of discrete DC sensors and
actuators.
There are two DC 16-circuit source blocks, which provide current to field
output devices:

24 VDC Source block (IC66*BBD022), for use with 2-wire and 3-
wire solid state sensors and electromechanical sensors.

24/48 VDC Source block (IC66*BBD020), for use with 3-wire solid
state sensors and electromechanical sensors.
There are also two DC 16-circuit sink blocks, which receive current from
field output devices:

24 VDC Sink block (IC66*BBD023), for use with 2-wire and 3-wire
solid state sensors and electromechanical sensors.

24/48 VDC Sink block (IC66*BBD021), for use with 3-wire solid
state sensors and electromechanical sensors.

Features
DC 16-Circuit Source/Sink I/O Blocks have 16 discrete circuits, each
easily configured to be an input, tristate input, or output. Output circuits
can be connected directly to input circuits without the use of other
components or inversion of logic states.
Control power is tapped off the input/output device voltages wired to the
terminals. No separate block power supply is needed.
Configurable features include:

Output Pulse Test capability

Selectable Input Filter Time from 10ms to 100ms

Output powerup defaults

Output Hold Last State or default
The block’s advanced diagnostics can pinpoint causes of installation and
run-time errors. Diagnostics features of these blocks include:

Electronic short circuit protection

Overtemperature protection

Failed switch detection

Open wire detection for tristate inputs

Overload detection and shutdown

No-load detection
