General
The RD9021 I/O Interface Module is designed to expand D25 connections from the rear
of MAXPRO-Net I/O subracks to easy-to-use screw terminals on a PCB module.
This module can be used on any of the MAXPRO-Net "MX" range of I/O subracks such
as the HMX1132, HMX1600, and the HMX1676.
MAXPRO-Net I/O Modules compatible with the RD9021 are RD315, RD316, RD400,
MX440, RD490 and RD494.

Installation
The module simply plugs into the female D25 connector on the rear of the subrack and
immediately provides easy-to-use screw terminals for field cable terminations.
Two links (L1 and L2) are provided on-board to alter the type of termination from the D25
connector to terminal strips B & D. Refer to the illustration overleaf for full termination
details.
