The 8310-845 is a programmable 3 relay logic module that may be used for multiple applications, including simple timing, door mounted sensor inhibiting and advanced relay sequencing. The 8310-845 contains 12 different programmable functions which allow the technician to carry one and only one module. In addition to the ability to provide up to 3 Amps through the first two relays and 1 Amp through the third relay used in ‘‘DRY’’ mode, the 8310-845 provides the ability to select a ‘WET’ voltage output of up to 1 Amp on Relay 1 to power electric strikes and magnetic locks without the need for an external power supply. This feature can greatly simplify the installation (as long as the power supply powering the 8310-845 is rated for 1 Amp).

The ‘WET’ output can also be set using jumpers to output DC if the 8310-845 is supplied with AC, otherwise it will just pass the AC voltage that is supplied. Similarly if powered by DC, the ‘WET’ output will only output DC. The module provides removable screw terminal connectors which help to reduce extra wiring.

Another feature of the 8310-845 is that it also provides an easy 2-button digital programming with a user-friendly display, hold times being adjustable from 0 to 60 seconds, and delay times being adjustable from 0 to 60 seconds with ¼, ½ and ¾ also available to the applicable functions.
