7300w² Monitor Instruction Manual
4.4.6 Relay Outputs (Alarms)
The relay outputs are 3 way terminal strips, located in the middle of the termination bank. The 7300w²
Monitor offers 3 SPCO relay contacts that are user configurable.
Please refer to the “Alarm Configuration” section of this manual for details of how to configure the relays for
alarms or process control outputs.
The relays can switch non-inductive loads up to a maximum of 5A, and withstand voltages up to 240VAC.
Please note, for “Alarm” applications the relays are fail safe. Once configured, the relays will remain
energised in a non-alarmed state (Healthy), therefore N/C will be “Open Circuit”, and N/O will be “Closed
Circuit”. During an Alarm condition, system fault or power failure the relay will de-energise, returning back to
the state illustrated on the label. If the alarm has not been configured, the relay will remain de-energised.
4.4.7 Analogue Outputs
The 7300w² Monitor provides the user with two 0/4-20mA analogue outputs. The Analogue outputs are
connected to the 4 way terminal strip located towards the right of the terminal bank.
Each analogue output can be configured as either 0-20mA or 4-20mA, and can represent any measurement
configured. This configuration set-up is detailed in the “Output Configuration” section in this manual.
The outputs are Active (self-powered loop, does not require external powering) . Each analogue output can
drive a maximum load of 750 ohms.
