Option Modules

Every controller comes with a "concise" set up guide. If you would like a full manual that covers the three controllers, order it here!

A maximum of two additional relays may be fitted to a controller, provided no re-transmission or transducer power supply is required. They can function as alarms or one can be a second control output (for Heat/Cool applications)
Rating is 2A 240Vac non inductive

An analogue retransmission module that can be configured for 0/4-20mA, 0/1-5V or 0/2 -10V. It can be ranged over a reduced portion of the total instrument range - if the instrument is set for 0-760C, the retransmission can be configured to to be say 0-300C for the full 4-20mA

This module gives a nominal 24Vdc 20mA supply suitable for powering two wire transmitters. The advantage of using the internal supply is that wiring is simplified and single loop integrity is maintained. NOT SUITABLE FOR THE 6100

This module allows up to 32 instruments to be connected on one 2 wire RS485 data highway using West ASCII protocol.
Modbus protocol is available, but to special order only. Please email your enquiry.

This module allows the remote selection (by contact closure) of a second setpoint value. Note that this module is mutually exclusive with the RS485 comms module.
