Product description

With their improved interface, technical functionality and field flexibility, the WEST 6100, 8100 and 4100 give you the best comprehensive control for most temperature and process control loops.

They have a universal input and are available with a red and green displays. Plug-in modules allow up to 2 alarm relays (latching or non-latching), PV retransmission, remtote set point (RSP) or transmitter PSU





Control types

Full PID with Pre-tune, Self-tune, manual tuning, or On-Off control.
Heat only or heat & cool.



Selectable from front panel or via digital input, with bumpless transfer.


Output configuration

Up to 3 possible, for control, alarm, 24VDC transmitter power supply or retransmit of process value or setpoint.


Alarm 1 & 2 types

Process high, process low, SP deviation, band, logical OR / AND.
Also 1 loop alarm for process control security.
Process alarms have adjustable hysteresis.


Human Interface

4 button operation, dual 4 digit 10mm & 8mm high (6100+, 8100+) and 13mm & 10mm high (4100+) LED displays,
optional choice of colours (Red/Red, Red/Green, Green/Red or Green/Green), plus 5 LED indicators


PC configuration

Off-line configuration from PC serial port to dedicated config socket (comms option not required).
Configuration Software for Windows 98 or higher.
West Part Number: PS1-CON
