MOD 30ML Operation
INTRODUCTION

without loop power. The analog output module supplies 4-20mA or 0-20mA. All analog I/O
modules are individually, optically isolated to 250Vrms continuous.
Digital I/O
Digital I/O is selected by the user through use of digital I/O modules. Options include both isolated
and non-isolated modules. Solid state relay versions offer high isolation voltage capability. Non-
isolated modules are compatible with TTL logic levels and provide the ability to interface between
similar modules without the need for an external power supply. The Mechanical Relay output
module supports Form A, Form B and Form C relays.
Remote I/O (requires Application Builder Software support)
Remote I/O input and output modules expand the I/O capability to a total of 100 discrete points.
The module communicates over the Remote I/O Network, an RS-485 fieldbus which connects to
the instrument via a 2020N RIO module. The RIO module does not need to use a
communications position leaving those two positions open for communications modules. Refer to
IB-23C601.
1.2.5 Communications (requires Application Builder Software support)
Two serial communications channels on each instrument allow up to two independent
networks to function simultaneously. The first channel is built-in and is selectable for either
Instrument Communications Network (ICN), RS-232 Modbus or RS-485 Modbus. The second
channel uses an ICN, RS-232 Modbus or RS-485 (2-wire or 4-wire forms) module.
