Series 8 IO Specifications

Specifications for Series-8 I/O modules are shown below.

2.2.1. TC/RTD

Function

The TC/RTD IOM module supports up to 16 channels of temperature inputs.

Notable Features

• TC and RTD operation

• Remote cold junction compensation capability

• 1 Second PV scanning with OTD protection

• Configurable OTD protection (See below)

• Temperature points can be added in 16 point increments

Temperature Support

The Temperature variable is collected from all points at a 1 second rate. The 1 second update includes a

configurable check for Open Thermocouple Detection (OTD) (see below) before propagation of the

temperature variable. All TC inputs include integral Cold Junction Compensation (CJC).

Sampling and Open Sensor Detect

The TC/RTD IOM supports a configuration parameter for Open Sensor Detect before PV delivery. With the

OTD configuration active, the PV is sampled and held while an OTD cycle is performed within the same

measurement window. If the OTD is negative, the PV is propagated up through the system. If the OTD is

positive, the PV is set to NAN and the input channel soft failure is set. In this way, no inappropriate control

action occurs for PV values that are invalid due to an open thermocouple. PV sampling/reporting incurs no

added delays from OTD processing.
