CIO-ERB08
The CIO-ERB is a family of
electromechanical relay racks
designed to be compatible with the
CIO-DIO family of digital I/O plug-in
boards. There are three models in
the family: the CIO-ERB48 contains
48 relays, the CIO-ERB24 contains
24 relays and the CIO-ERB08
contains 8 relays. All relays are
form C electromechanical capable
of handling 6 A at 24 Vdc or 3 A at
120 Vac. Field wiring is accomplished using screw terminals for
each relay. The screw terminals
allow you to connect signals via
12-22 AWG wire. The digital I/O
board connects to the CIO-ERB
racks via a standard 37 conductor
cable, or 50 conductor cable
depending on the CIO-ERB model.
CIO-ERB08
The CIO-ERB08 is an 8 channel
electromechanical relay board.
It features 8 form C relays. Field
connections are made through
screw terminals. The connection
to the digital I/O board is through
a standard 37 pin D connector. A
second connector is provided as a
pass through. The CIO-ERB08 can
connect directly to a CIO-DIO24,
CIO-DIO24H or CIO-DIO24/CTR3
using a C37FF-2 cable.
CIO-ERB24
The CIO-ERB24 is a 24 channel
electromechanical relay board. It
provides connection to the digital
I/O board using either a 37 or 50
pin connector. The 37 pin connector
is used to connect to 24 channel
digital I/O boards such as the
CIO-DIO24, CIO-DIO24H and CIODIO24/CTR3. The C37FF-2 cable
may be used for connection to
these boards. The 50 pin connector
is used to connect to the
CIO-DIO48, 96 and 192. The
C50FF cable is used for the
connection. Since the 50 pin connectors on the digital I/O boards
carry 48 digital I/O lines, a second
50 pin connector is located on the
CIO-ERB24 to connect a second
CIO-ERB24. The second connector,
labeled “OUT”, swaps the digital I/O

CIO-ERB48
The CIO-ERB48 is a 48 channel
relay board designed for high density applications. The 50 pin connector is laid out to connect directly to
the CIO-DIO48, 96 & 192 with a
C50FF-2 cable.
BUFFERS & PULL-DOWNS
The CIO-ERB inputs, from the digital
I/O board, are pulled to a steady
state by circuitry on the board, so
they will not randomly open or close
on power-up. Also, buffer/drivers
on board accept signals from simple
8255 type digital I/O boards.
POWERED FROM THE PC
The CIO-ERB racks do not require
110 Vac power. They run on the
personal computer’s 5 V power
supply or an external 5 V supply.
Power is connected through a 4 pin
connector, just like that found on all
PC power supplies.
CONTROL WIRING
The CIO-ERB racks have screw
terminals for connecting your field
wiring to the relays. Each relay has
three connections; Common,
Normally Open and Normally
Closed. The screw terminals are
high-quality jaw type that will not
bind when removing wires. Wire
gauges 12-22 AWG may be used.
INDUCTIVE LOAD WARNING!
The CIO-ERB boards are excellent
for switching inductive loads, but
only with the correct DIO board.
Do not use 82C55 based DIO
boards because these may be reset
by the ‘inductive kick’. Choose
instead the new CIO-DO48H, 96H
or 192H, which cannot be reset.
