ABB optical fiber adapter RDCO-02C module is brand new

Description

RDCO-02C In hazardous locations, I/O Station power must be turned off before inserting/removing module.

Failure to observe this precaution may result in personal injury, system malfunction and/or damage

to the equipment.

Warnings

Explosion hazard. RDCO-02C When in hazardous locations, turn off power before

replacing or wiring modules. Do not remove or insert external modules with

power applied. Personal injury, system malfunction and/or damage to the

equipment may occur.

In non-hazardous areas, for personal safety, field power should be off while

removing or inserting a high-voltage I/O module. Avoid contact with module

wiring and with the exposed connectors on the I/O Terminal Block.

Equipment labeled with reference to Class I, Groups A, B, C, and D, Div. 2

hazardous locations is suitable for use only in non-hazardous locations or in

Class I, Div. 2, Groups A, B, C, and D locations.

Explosion hazard: Substitution of components may impair suitability for

Class I, Division 2.

The module receives power from the Bus Interface Unit for its own operation.

An external 120VAC supply is needed to power the input devices. Module inputs respond to

voltage levels from 0 VAC to 132 VAC.

LEDs

RDCO-02C Individual LEDs, visible through the transparent portion of the module top, indicate the on/off

status of each input. The PWR LED is on when backplane power is present.

Host Interface

Intelligent processing for this module is performed by the Bus Interface Unit or elsewhere in the

system. This includes configuring features such as input defaults and fault reporting. The module

has 8 bits (one byte) of discrete input data. A Bus Interface Unit is required to provide this input

data to the host and/or local processor.

RDCO-02C A network of resistors and capacitors establishes input thresholds and provides input filtering.

Optoisolators provide isolation between the field inputs and the module’s logic components. Data

from all 8 inputs is placed into a data buffer. The module’s circuit LEDs show the current states of

the 8 inputs in this data buffer.

A parallel-to-serial converter change input data from the data buffer into the serial format needed

by the Bus Interface Unit.

After checking the Board ID and verifying that the module is receiving appropriate logic power

from the Bus Interface Unit (which is reflected by the state of the module’s Power LED), the Bus

Interface Unit then reads the filtered, converted input data.
