The PT8AIIS is a 8 channel current input module. The inputs are fully isolated from input to logic and between inputs. This module is ideal for monitoring existing 4-20mA current loops which are isolated from each other and cannot be connected to a common point of reference.

The standard setting for the PT8AIIS module is 0 – 20mA input current which represents an output value of 0 – 4095 (12 bits) in the corresponding Modbus register. To obtain an output value of 0 to 4095 for an input signal of 4 to 20mA the offset switch is switched on. This module can also be configured for a 0 – 20.000mA input range or +/- 20.000mA input.

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.
