1. RYB-8 Relay Board
1.1 Introduction
The MCN-RYB-8 board is a relay board accessory to the MCN Monitoring and
Control Network product family.
The MCN-RYB-8 board has the following features:
•(8) DPDT Relays (Configured to switch circuit pairs).
•Hi-reliability long-life sealed relays.
•Relays rated for low-level (dry circuit) audio switching, up to 2A.
•Selectable 600 Ohm terminations for the Normally Open, Normally Closed, or
Common circuits (may be de-selected).
•LEDs to indicate which relays are active.
•Control Connector (relay coil inputs) which is pin-compatible with the MCN
IOB modules.
•25-pair telco connectors used for control inputs and relay outputs.
•Jumpers to control adjacent relays.
•Jumpers for Sub-Category strapping for MCNRCD variable status text
messages.
•Optional EIA 19” rack-mount panel available for mounting (4) MCN-RYB-8
boards.

1.2 Circuit Description
The MCN-RYB-8 board has 8 identical circuits. The following will describe the
first such circuit.
Relay K1 has the following I/O bits associated with it:
J2
Pin Relay I/O Bit Relay Board Function CIB Module Signal IOB Mode 1 Signal
21 1 1 Input/Output VOTE 1 Input/Output 1
22 1 2 Output RECEIVE 1 input 1
20 1 3 Input/Output DISABLE 1 Input/Output 9
23 1 4 Output FAIL 1 input 9
I/O bits 1 or 3 can be used as inputs to drive the coil of the relay (see Figure 1).
1.2.1 Relay Control Inputs E1-E8 “B” Side
Each relay has its own jumper block (E1-E8) to select the input that will drive the
relay coil. Each relay can be controlled from either I/O bit 1 or 3 associated with
it, depending upon the position of the B1 or B3 jumper in jumper blocks E1-E8.
The following table shows the jumper configuration for relay K1:
J2 Pin I/O Bit Jumper
21 1 E1-B1 In (Default)
20 3 E1-B3 In
Only one jumper (E1-B1 or E1-B3) should be installed at a time.

CTI Products, Inc. MCN RYB-8 Relay Board Manual
1.2.2 Sub-Category Jumpers E1-E8 “A” Side
When you use the MCN Relay Board with an MCN IOB module and the
MCNRCD PC Software, you can use the “A” side of jumper blocks E1 through
E8 to provide static sub-category status text selections. This will allow you to
specify different status text messages (On/Off, Up/Down, Main/Standby, etc. as
defined in the MCNRCD.CFG file) for different relays on the MCN-RYB-8
board.
For relay K1, the jumpering is shown in Table 1:
J2
Pin Relay I/O Bit Jumper CIB Signal IOB Mode 1 Signal MCNRCD Bit Weight
21 1 1 E1-A1 In VOTE 1 Input/Output 1 1
22 1 2 E1-A2 In RECEIVE 1 input 1 04
20 1 3 E1-A3 In DISABLE 1 Input/Output 9 10
23 1 4 E1-A4 In FAIL 1 input 9 40
Table 1 - Sub-Category Jumpers
Since I/O bit 1 is normally used to control the relay, I/O bits 2-4 are available for
sub-category selection. Up to (8) sub-categories can be configured with these 3
bits. When a jumper is inserted, the bit is active. See the MCNRCD Software
Manual and IOB hardware manual for more details on sub-categories.
1.2.3 Adjacent Relay Drive Jumpers E17-E23
In some applications you may need to drive two relays from the same input
signal. You can use jumpers E17-E23 to connect a relay's coil to an adjacent
relay's coil.
E17 jumpers the coils for relays 1 & 2 together. E18 jumpers relays 2 & 3, and so
on.
Caution
When you insert the Adjacent Relay Drive jumpers (E17-E23), be sure that you
have only one input active (E1-E8 "B" side) for each set of relays that are
connected together.
These jumpers are normally not installed from the factory, unless a custom
configuration is ordered.

1.2.4 600 Ohm Termination Jumpers E9-E16
A selectable 600 Ohm termination is available for each relay. The termination is
used in some telephone line applications when you need to terminate an unused
phone line. Jumper blocks E9 to E16 control the terminations. You can terminate
the Normally Open, Normally Closed, or Common pair as shown in Table 2 and
Figure 2

1.2.8 Relay Input Connections - J2
The relay input connections appear on a 50-pin female micro-ribbon telco-style
connector, J2. The relay input connector is laid out to match the MCN IOB
module pin-for-pin. J2 can be connected to the IOB module directly through a
25-pair straight-through male to male cable.
Since the MCN CIB module was originally set up to match the Digitac P805
pinout, the signals are a bit scrambled. For convenience, the pinouts are as shown
in two tables, the first sorted by relay and function, and the second sorted by pin
number. The corresponding signal names for the CIB and IOB modules are also
shown.

1.3 Mounting and Cabling
The following options are available for the MCN-RYB-8 Relay Board:
S2-60646 Relay Board quad rack-mounting panel
S2-60645 Ribbon Cable assembly for CIB or IOB to Relay Board
(25-pair)
The Mounting Panel mounts in an EIA 19” rack. It can hold 4 MCN RYB-8
boards. It has snap-in standoffs for board mounting and includes tie-points for
use with cable ties. It is 10.5” high (6 Rack Units).
Figure 3 shows a view of the Mounting Panel from the front side of the equipment
rack. Since the Relay Boards are mounted to the opposite side, they are shown as
if the panel and boards were transparent. This figure also shows the ribbon cable
used to connect the relay boards with an IOB or CIB module.

2. Hot-Standby Power Supply Option
2.1 Introduction
The Hot-Standby Power Supply Option is a redundant 12Vdc supply to power the
relay coils of the RYB-8 Relay Boards. This option consists of dual 100/240Vac
to 12Vdc Power Supplies (81-11665), a Relay Power Distribution Board (S3-
61193), and mounting hardware. A single (non-redundant) Power Supply is also
available. For this option, the information in Section 5.1 should be ignored.
Part Number Description
S2-61084 Hot-Standby Power Supply Option
S2-61390 Hot-Standby Power Supply Option with Rack Panel
S2-61240 Single Power Supply Option
S2-61117 Single Power Supply Option with Rack Panel
2.1.1 Power Distribution
The outputs from the redundant power supplies are independently connected to
inputs on the Relay Power Distribution Board. Each supply input on this board is
separately fused with an automotive style fuse, and has an “OK” and “FAIL”
LED indicator. When the input supply is present (and the input fuse is intact), the
corresponding green “OK” LED is lit. If either input supply is not present, or the
fuse is blown, the green “OK” LED for that input is turned off, and the red
“FAIL” LED is lit. In addition, an on-board buzzer sounds when either supply
input is not present, or if any of the input (F5, F6) or output (F1 – F4) fuses are
blown. The buzzer may be disabled by moving Jumper E4 to the “OFF” position.
The Relay Power Distribution Board passes the supply current from the input
supplies to four outputs (one for each relay board on the mounting panel). Each
supply output is separately fused, and has an “OK” and “FAIL” LED indicator.
When the output supply is present (and the output fuse is intact), the
corresponding green “OK” LED is lit. If an output supply is not present, or the
fuse is blown, the green “OK” LED for that output is turned off, and the red
“FAIL” LED is lit.
2.1.2 Status Indication
Three status signals are available to inform monitoring equipment if the redundant
power supplies are functioning or if any fuses are blown. The three status signals
are driven from solid state relays, with an output rating of 60V, and protected
with 0.5A fuses. (These fuses are non-field replaceable, since they are soldered.)
These signals can either be referenced to the GND signal by installing the
appropriate jumper, or isolated by removing the jumper. Table 11 lists the
terminal connections for these signals and jumpers for referencing to GND.
