CTI Products, Inc. MCN RYB-8 Relay Board Manual

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:
