The PM8AI/I ISO 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 currents which are isolated from each other and cannot be connected to a common point of reference.

The standard setting for the PM8AI/I ISO 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.


PROMUX RS485 (I/O Modules)

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

The PROMUX system consists of stand-alone Digital and Analog Input and Output modules which are connected together on a RS485 two wire multi-drop network. The modules communicate using the MODBUS RTU protocol.

A 32bit ARM CPU is used in the modules to provide high speed data processing and fast communications turn around times. Multiple baud rates are selectable from 2400 to 115200 baud.

All PROMUX modules plug directly onto an industry standard DIN rail. All modules have a minimum isolation of 1000VAC rms between the field and logic. The modules have been equipped with status led’s which are used to indicate the status of the Inputs or outputs. This visual indication assists with fault finding and diagnostics.
