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 24-

module board, etc.

•

8, 16 and 24-module I/O boards are connected to J2 and J3 on the RIB.

•

32-module boards connect to J4 only.

The system safe and global alarm outputs are available via J2 and TB1 only. To con-

nect to all of the digital inputs and outputs, use two 24-module boards.

A 32-module board connected to J4 provides outputs for 32 heat-only loops or for 16

heat/cool loops.

MLS300 and CLS200 controllers have a 50-pin, SCSI-II, female connector for digi-

tal I/O. You will have to make or obtain from Watlow Anafaze a cable that connects

from SCSI to ribbon cable in order to use the RIB with these controllers.
