The PT8DIO module is an 8 channel digital input and 8 channel digital output module.

The inputs are isolated from the logic by bi-directional opto-couplers. The common is connected internally to either the -volts or +volts field power supply terminals using a jumper link which is situated inside the housing.

The inputs have internal counters associated with them. These counters are 32 bit counters allowing a count value from 0 to 4294967295. The count value can be cleared by writing a zero to the associated registers or preset to any other value using the same method.

Note: The count values are not battery backed-up and will be lost if power is turned off.

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.
