Relay Interface Board Installation Guide Relay Interface Board Installation Guide Introduction The Relay Interface Board (RIB) replaces the standard I/O terminal board. It connects a Watlow Anafaze controller to a third-party I/O board with 8, 16, 24, or 32 relays. This document lists system requirements, specifications and explains how to install and wire the RIB.
Relay Interface Board Installation Guide System Requirements Choose which of the controller’s digital inputs and outputs are needed. Refer to Table 3 and 4 for connections for 24-module I/O boards or Table 5 for connections for a 32-module I/O board. An 8-module I/O board contains the first eight modules of the 24-module board, a 16-module board contains the first 16 modules of the 24module board, etc. • 8, 16 and 24-module I/O boards are connected to J2 and J3 on the RIB.
Relay Interface Board Installation Guide Hardware Requirements Choose I/O modules designed to operate with +5 Vdc power. Watlow Anafaze systems are designed to operate at this voltage. Choose I/O boards which have 50-pin headers with long latch levers. Short latch levers will not Watlow Anafaze cables. Calculate the maximum current requirement of the desired I/O boards. If they require more current than the controller can supply, use an external power supply.
Relay Interface Board Installation Guide Installation These instructions assume the controller has previously been installed. Tools Needed Mounting 4 Four, #6 screws Screwdriver 1. Choose a mounting location large enough to accommodate the RIB, the I/O board or boards, the ribbon cable or cables and wires that connect them. 2.

Relay Interface Board Installation Guide Wiring These instructions explain how to connect the RIB to the Watlow Anafaze Controller and to the I/O board. Ribbon Cable Connect the ribbon cable to the controller. Plug the other end of the ribbon cable into the header labeled J1 on the Relay Interface Board. The red stripe on the ribbon cable should line up with Pin 1 on the board. Plug one end of the I/O board ribbon cable into the I/O board and the other end into the RIB.
Relay Interface Board Installation Guide Power Connections Choose one of the following options for installing and configuring the jumper on JU1 appropriately for your I/O board. • Option 1: 8, 16, and 24-module I/O boards only: Jumper JU1 in position A to get power from the controller to the I/O boards via the ribbon cable. • Option 2: 8, 16 and 24-module I/O boards only: Jumper JU1 in position B to disconnect the controller power supply. Jumper the I/O boards to get power from the ribbon cable.
Relay Interface Board Installation Guide Additional Terminals The Relay Interface Board contains a 5-pin terminal block (TB1) with these functions: TABLE 1. TB1 Functions TB1 Function 1 +5 Vdc power 2 Power common 3 Global alarm output 4 CPU Watchdog output 5 Pulse input These terminals are directly connected to the controller. They allow connection to separate sensors, SSRs, PLCs and safety controls. Jumpers The RIB has three sets of jumpers: JU1, JU2 and JU3.
Relay Interface Board Installation Guide TABLE 2. Jumper Positions Jumper Jumper Position A Jumper Position B JU1 Controller supplies +5 Vdc to power both 24-module I/O boards. TB1 terminal 1 can supply power to a 32-module I/O board. Controller power supply is disconnected. TB1 terminal 1 can connect +5 Vdc power from an external supply to both 24-module I/O boards. JU2 Module 3 (on the I/O board connected to connector J2) is connected to the controller’s digital input 1.
Relay Interface Board Installation Guide Applying Power After wiring the I/O board modules and selecting the appropriate jumper positions, power may be connected to the system. If power is present at the RIB, the green LED labeled RLY PWR will light. Testing Your System Test the system after connecting power. For specific information on testing controllers, refer to your controller manual. • To test a PID control output, set the appropriate loop to Manual mode and set the output to 100%.
