Field Devices

Depending on the distance from the controller, field
devices can be supplied with power by the same
transformer used for the Panel Bus I/O Modules, or by a
separate transformer, using cables as specified in Table 22.

24 VAC power 16 AWG (1.5 mm
0...10 V signals 28 – 14 AWG (0.081 – 2.08 mm
For wiring field devices, see section "Powering Panel Bus
I/O Models and Field Devices" on page 19.
Routing Cables to Field Devices
Route low-voltage signal and output cables to field devices
separately from mains cables.
Table 23. Minimum distances to power mains cables
cable min. distance
shielded 0.4' (10 mm)
unshielded 4' (100 mm)
All low-voltage signal and output cables should be
regarded as communication circuits in accordance with
VDE 0100 and VDE 0800 (or NEC or other equivalent).
• If the general guidelines for cable routing are observed,
it is not necessary to shield field device signal and
power supply cables.
• If, for whatever reason, the routing guidelines cannot be
observed, the field device signal and power supply
cables must be shielded.
– Shielding of cables leading to field devices must be
grounded only at one end.
– Do not connect the shield to the CIPer Model 50
controller.
LONWORKS
COMMUNICATIONS

General Information

The CIPer Model 50 can be connected to L
networks. This requires the use of an IF-LON (see section
"IF-LON" below), which is then plugged into to the CIPer
Model 50 controller's USB 2.0 Host Interface (see also
section "USB 2.0 Host Interface" on pg. 7).
This permits individual CIPer Model 50 controllers to be
connected / disconnected from the L
without disturbing the operation of other devices.
The L W network is insensitive to polarity, eliminating
ON ORKS
the possibility of installation errors due to miswiring.

conductor wire.
When possible, use Honeywell AK3781, AK3782, AK3791,
or AK3792 cable (US part numbers). See Excel 50/500

IF-LON2
Optionally, communication with physical I/O modules, with
room and zone controllers, and with WEBS Spyder
controllers can utilize LonTalk.
The IF-LON is equipped with a free-topology transceiver
(FTT10A) for communication (at a data transmission rate
of 78 kbps) on L
protocol).
