S-UNC-AI – Analogue Input Card
S-UNC-DI – Digital Input Card
Analogue Input Card
Allows the monitoring of up to 16 Analogue Inputs (per card), which allows it to
monitor most transducers and sensors used in the building services industry: 0 to 10V,
0 to 20mA and 0 to 10k
Ω
selectable via jumper selection.
Digital Input Card
This card allows the monitoring of up to 16 Digital Inputs (per card). The card will
monitor normally open or normally closed voltage free contacts.
The digital input card can also be used for up to 16 totalising pulsed inputs (frequency
10Hz) received from utility meters, thus providing an efficient method of monitoring
energy consumption of buildings and installed plant.
Software programmes also permit up to 8 maximum demand meters to be monitored
and automatically provide load shedding routines to ensure that maximum demand is
not exceeded.

S-UNC-CMD – Digital Output Interface Module
Analogue Output Card
Analogue Outputs provide modulated control of valves and dampers, Variable Speed
Drives (VSDs) and inverters.. The Analogue Output Card allows up to 16 channels,
providing a 0 to 10Vdc or 0-20mA output (two per card).
Digital Output Card
A Digital Output Card enables individual items of plant such as pumps, fans, boilers
etc. to be switched on or off in response to the programmed control requirements.
Up to 16 outputs are available from each card to switch the plant via the Command
Interface Module.
Digital Output Interface Module
This module provides a relay interface between the Digital Output Card and the
switched plant. Up to two modules (8 channels per module) can be fitted within each
S-696 controller. Additional modules may be mounted in adjacent interface panels or
control panels. Each relay is provided with Hand/Off/Auto switches.
