Product Description
The A Series ® Lighting Controller (cat. no. 10092046P2)
is a fully programmable Native BACnet/MODBUS System
Controller. Standard communications ports are RS-232
and RS-485, with an Ethernet option. The unit is easily
mountable in a GE enclosure and is designed to control
up to 66 breakers. The device comes standard with 16
digital inputs for light switch control, three universal
(analog) inputs, and one dry contact output. It also
contains a second RS-485 subnet port to communicate
with expansion modules providing expansion and local
programming capability.
Time-of-Day and Day-of-Week Scheduling. The A Series
Lighting Controller has an on-board real-time clock
calendar, which can be used to control the breaker by time
of day and day of week, including daylight savings time,
leap year, and astronomical time. The controller has 16
standard schedules, which can have up to eight clock
periods per day, 16
ON / OFF transitions, independent
programming for the seven days of the week, plus two
holidays. Each holiday calendar can have up 90 holiday
dates.
Input Control. The Lighting Controller has 16 standard
switch inputs. Each input can be configured as two-wire or
three-wire with momentary or maintained input. There
are also three analog inputs that can be used to control
breakers or groups of breakers.
Lighting Zones. The GE Lighting Controller has 16
standard zones or groupings of breakers. The lighting
grouping is used to bind Schedules, Breakers, and Inputs
to control a group of breakers.
Product Specifications
Power Requirements
• 24 Vac ±15%, Class II
• 50 VA
• 50/60 Hz
• One per controller
• Remote modules powered separately
Ambient Ratings
• –20° t0 70° C
• 10 to 90% RN (noncondensing)
Communication Ports
Ethernet (optional)
• Optional twisted pair (10BaseT) @ 10 Mbps
• Installation onto local Ethernet/IP network should
use standard IT installation and security practices.
Lighting Controllers must be installed behind a NAT
(Network Address Translation) and firewall.
NET1 – Main LAN (BACnet MS/TP)
• BACnet MS/TP Communications Speed @ 9,600,
19,200, 38,400, or 76,800 bps; default 76,800 bps
• MODBUS Communications Speed @ 9,600, 19,200,
or 38,400; default @ 9600 bps
• Maximum of 99 nodes per MS/TP segment (50
without a repeater)
NET2 – SubLAN (LINKnet)
• LINKnet @ 76,800 bps
• Maximum of seven LINKnet devices (four Remote
Input Expansion Modules, one Standard Input
Expansion Module, two dimming modules) per
controller plus remote keypad interface.
Serial RS-232
• PC connection for up to 38,400 bps with a serial
straight cable. The cable should have DB9 male and
female connectors at the ends. Pins 2, 3, and 5 are
connected.
• RS-232 baud rate settings can be changed by
selecting port3 PTP type in the BACnet Settings
object (NET1). The controller must be reset for the
changes to take place. Communication with it must
use the new settings.
Serial RS-485
• Use 22–24 AWG twisted pair with a termination of
100–120 ohms, capacitance of 17 pF/ft or lower, with
a braided shield.
• Maximum length of an RS-485 daisy chain is 4000 ft
(1200 m). This will only work reliably for data rates
up to 100,000 bps.
• Use maximum data rate of 76,800 bps.
Service Port
• RJ-11 jack for service tool
• LCD keypad directly uses the service port with the
enclosed cable.
Inputs
Universal Analog Inputs – Jumper configurable for the
following input types:
• 0–5 Vdc
• 0–10 Vdc
• 10 K thermistor
• Dry contact (using 10 K thermistor jumper setting)
• 4–20 mA
Local Override Input and Switch Inputs
• 16 light inputs per module, for use with switches,
push button, and/or maintained light switch
• Standard three-wire connection or two-wire with
jumper, as illustrated in Figure 1, Figure 2, and
Figure 3.
