I/O Modules

The following I/O modules are available to create a custom control solution.

 16 Channel Universal IO Module Galavanically isolated Input/Output to chassis (p.27)

 8-point universal analog input modules: Galvanic isolation point to chassis inputs may be mixed on a module and may include multiple thermocouple types,

RTDs, ohms, voltage or mill voltage types – all easily assigned using the Process Control Designer configuration tool. 

High point-to-point galvanic isolation simplifies installation and saves the expense of external isolation hardware (p.6).

 16-point high level analog input module: each point is configurable for V or mA. Galvanically isolated point to

chassis. Galvanically isolated point to point (p.10). 250-ohm shunt resistors can be added per channel.

 4-point galvanically isolated analog output module.

Galvanically isolated point to chassis supports from 0 to 20mA each (p.12).

 8-point analog output, galvanically isolated in 2 groups of 4 points. Galvanically isolated point to chassis.

Supports from 0 to 20mA each (p.13).

 16-point analog output, galvanically isolated in 4 groups of 4 points. Galvanically isolated point to chassis.

Supports from 0 to 20mA each (p.14).

 16-point digital input modules: Contact closure type, DC Voltage, AC Voltage and AC/DC voltage types (p.15).

Galvanically isolated in groups of 8 channel to chassis

 32-point digital input module: DC voltage. Galvanically isolated point to chassis. Galvanically isolated in 2

groups of 16 points (p.1915).

 8-point AC or 16-point DC digital output modules (sinking type). Galvanically isolated point to chassis.

Galvanically isolated in 2 groups of 8 points (p.18).

 32-point digital output: DC voltage (sourcing type).

Galvanically isolated point to chassis. Galvanically isolated in 2 groups of 16 points (p.23).

 8-point relay output module: four form C type and four form A type relays. 

Galvanically isolated point to chassis. Galvanically isolated relay to relay (p.20).

 4 channel Pulse/Frequency/Quadrature I/O module.

Galvanically isolated point to chassis (p.24).

Remote Terminal Panels 

Optional DIN rail mounted Remote Terminal Panels (RTPs) are available for use with pre-wired cables to reduce installation time and labor expense. 

Four types of RTPs are available: analog inputs, relay outputs, redundant I/O and other I/O modules. 

Three cable lengths are also available to match hardware to installation variations. 

Analog inputs RTPs include transmitter shunt resistors and transmitter power terminals with individual circuit fuses. 

The Relay Output RTP includes a fuse and power disconnect switch for each output. 

All the three types of RTP panels also switch power to allow module removal and installation under controller power. 

Key Features
