The PT4RO module has 4 normally open/ normally closed relay outputs. These modules may be used when a higher drive capability is required, or when isolation between outputs are required.

Each output can be individually switched on or off, or all outputs can be set up at the same time by writing a single number to the output register which represents the status of all outputs.

An output watchdog timer can be configured to switch off all the outputs if there has been no communications with the module for up to 255 seconds. A value of 0 seconds will disable this timer and the outputs will remain in the last programmed state.

PROMUX TCP (TCP/IP I/O Modules)

PROMUX TCP is an innovative modular I/O system which provides a simple solution for distributed I/O requirements.

The PROMUX TCP system consists of stand-alone Digital and Analog Input and Output modules which are connected together on an ETHERNET 10/100Base-T network using the MODBUS TCP protocol.

The PROMUX TCP modules also have built in web servers. This enables configuration and diagnostic data to be accessed via a standard web browser.

All PROMUX TCP modules plug directly onto an industry standard DIN rail. All modules have isolation between the field and logic.
