4.3.4 Digital Output to a Relay – Recommended connection for all 12-30V DC Relays
Note: Wiring connection from voltage supply to +24V terminal on instrument is not
compulsory, however it will prolong battery life.
4.3.5 Digital Output to a Relay – For up to 50V DC and 50V AC Relays
Note: This output type is not internally protected from voltage spikes from inductive loads, a
diode must be fitted as shown for DC loads, or a Metal Oxide Varistor fitted for AC circuits.
