UNIVERSAL INPUT (UI) CIRCUITS
See Table 2 for UI circuit specifications.
Table 2. Universal input circuit specifications
Air Outdoor Air Temp.
One Universal Input (UI-1*) is selectable as a fast digital pulse
NTC 20kOhm are recommended for use with these con-
trollers, due to improved resolution and accuracy when
compared to the PT1000.
The controller is available in eight models (see Table 1).
Before installing the controller, review the power, input, and
output specifications in section "Technical Data".
Hardware driven by Triac outputs must have a min.
current draw, when energized, of 25 mA and a max.
current draw of 500 mA.
Hardware driven by the analog current outputs must have
a max. resistance of 550 Ω, resulting in a max. voltage of
11 V when driven at 20 mA. If resistance exceeds 550 Ω,
voltages up to 18 Vdc are possible at the analog output
Electrical Shock Hazard.
Can cause severe injury, death or property
To prevent electrical shock or equipment damage,
disconnect power supply before beginning wiring or
making wiring connections.
The controller must be mounted in a position that allows
clearance for wiring, servicing, removal, connection of the
BACnet MS/TP Molex connector and access to the MS/TP
MAC address DIP switches (see Fig. 12).
The controller may be mounted in any orientation.
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of the
controller, or in areas where escaping gas or other
explosive vapors are present. See Fig. 4 and Fig. 6 for
