I/O Modules
The ROC800 and EXPs support various types of Input/Output (I/O)
modules, which can satisfy a wide variety of field I/O requirements
(refer to
Chapter 4, Input/Output Modules
). You can place I/O
modules in any available slot. I/O modules include:
Analog Inputs (AI).
Analog Outputs (AO).
Discrete Inputs (DI).
Discrete Outputs (DO).
Digital Relay Outputs (DOR).
Advance Pulse Module (APM).
Alternating Current I/O (ACIO).
Multi-variable Sensor (MVS I/O).
Highway Addressable Remote Transducer (HART
®
) Module.
Pulse Inputs (PI) – High/Low Speed.
Resistance Temperature Detector Inputs (RTD).
Thermocouple (TC) Inputs.
IEC 62591.
APP 485.
