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.
Part Number Description
S3-60644 Basic board with no jumpers installed
S2-60694 Board with standard jumpers installed
E1-E8: B1 installed (I/O Line 1 controls relays)
E9-E16: (2) jumpers installed in park position
S2-XXXXX Board with custom jumpering
Note: The MCN RYB-8 Relay board is pin-compatible with the IOB module and
is fully supported for operation with it. Although it is also pin- compatible with
the CIB Comparator Interface Module (in Spectra-TAC mode only), it is not
supported for use with CIB modules. References are made within this document
to the CIB Comparator Interface Module only for completeness, especially with
the MCNRCD PC Software.

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
Relay I/O Bit Relay Board
Pin
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
Function
I/O bits 1 or 3 can be used as inputs to drive the coil of the relay (see Figure 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:

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:

Relay I/O Bit Jumper CIB Signal IOB Mode 1
Signal
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.
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.
MCNRCD
Bit Weight
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.

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

3.3 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 25pair 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.

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).
