Product Description

The Delta 16 Input Controller is a Native BACnet Application

Controller that is fully programmable (via GCL+) and

communicates on an RS-485 LAN using the MS/TP BACnet

protocol. The controller includes an easy to mount enclosure

and is designed for a wide range of monitoring applications

requiring no more than 16 inputs. A secondary LINKnet

network is also supported for up to 4 Delta BACstats or other

Delta LINKnet devices.

The 16 universal inputs are jumper configurable.

Important Information

ORCAview OWS and controller firmware must all be of the same version number to be

compatible. When upgrading any of these products from older versions (i.e. 3.22 or 3.30), you

must upgrade all the remaining products. Exception: UL 864 model, DAC-1600-UL864 can be

used with V3.33 and V3.40 firmware.

UL864 Specific Considerations

Wiring to and from the device shall be through power-limited circuits.

Use only Core Components transformer, Model No. 120-024-100-2TF-CB, by Lectro

Components Inc. to power the device. (Delta Part # 440008)

Use only UL Listed Class 2 Power Supplies for auxiliary field devices.

Use only UL Recognized Ethernet Switch, 571-580, by Siemens for Smoke Control Systems

that utilize Ethernet communications.

Impedance value for which ground faults are detected is zero ohms.

Cautions or Warnings

This controller is an Electro-statically sensitive device. Proper ESD protection (ground strap)

should be used when installing this product so that damage to the product does not occur.

Equipment damage or loss of data may occur if these procedures are not followed as specified.

Installations requiring CE conformance: All wiring for CE rated products must use an extra low

voltage (SELV) or protective extra low voltage (PELV) transformer. Use safety-isolating

transformers, (Class II transformer) per EN61558. The transformer must be rated for 100% duty

cycle.

Mounting

The DAC-1600 includes a plastic enclosure that can be quickly mounted with two screws (not provided). This

controller should be mounted in an appropriate location within packaged equipment or another enclosure that

meets code requirements.

Controller Configuration

Derived Network Addressing

The DNA jumper comes ON by default. This allows the controller to

automatically configure a BACnet controller address. This should NOT be

removed unless you are assigning a BACnet controller number through

software. The BACnet controller number should not be confused with the DIP

switch setting, and each controller must still have a unique dip switch address

even when using software to define the controller number.

DNA

Controller Addressing

The Dip Switch is a binary switch. Each individual DIP switch represents a

unique value, which forms the controller address when added together.

To set the address, simply move the switches that add up to the controllers

desired address to the ON position.

Example: If the controller is to be address 5 on the network, set the switch

numbered 4 and the switch numbered 1 (equals 5) to the On position.

Note: Each controller on the same MS/TP segment must have a unique DIP

switch address.

Wiring General

All wiring must conform to NEC and local codes and regulations. Use earth ground isolating step-down Class 2

transformers. Do not use autotransformers. Determine supply transformer rating by summing total VA of product

and output loads.

Risk of Electric Shock or Fire

More than one disconnect switch may be required to de-energize the

equipment before servicing.

Input Class 2 Power Supplies are interconnected. Use only Class 2

sources suitable for interconnections.

All terminals are acceptable for Class 2 Circuit connections only

Use copper conductors only

Apply minimum 6.0 lb-in torque for tightening field wires into the terminal

blocks

Power

This product is designed to use a 24 VAC, Class 2 power supply. The proper specified cabling must be used.

(18 – 16 AWG, 2-conductor wire)

A single transformer may be used to power multiple controllers and/or auxiliary field devices (actuators, etc.)

provided the following conditions are met:

All devices MUST be ½ wave rectified. Mixing power between ½ wave and full wave rectified devices

will damage both the transformer and connected equipment.

The transformer is properly sized, including line losses for the total VA requirements.

Polarity is observed between controllers (with respect to 24~ and Gnd).

Each controller is grounded as shown in the diagram below. This is important to protect equipment and

ensure a common ground reference for RS-485 communications.

The transformer secondary is fused for its maximum rated load (4A max for Class 2 circuits).

Network Communication

The controller communicates on an RS-485 LAN using the BACnet MS/TP protocol. Refer to Delta Controls

Wiring Guidelines for further details.

MS/TP (RS-485) Wiring

For detailed information on MS/TP and LINKnet wiring refer to Delta Controls Wiring Guidelines.

The proper specified cabling must be used to ensure reliable communications. (22 AWG twisted

pair, 100-120 ohms impedance, 17 pF/ft or lower capacitance, with a braided or aluminum foil

shield.)

Controllers should always be wired together in a daisy-chain fashion. Attempting to connect them

using a starred or bus configuration will cause problems on the network.

Networks with a total length greater than 4000 ft or with more than 50 controllers require a

repeater (RPT-768).

LINKnet networks that have only 1-2 controllers, and have less then 100 ft of cable length do not

require network terminators.

Input Wiring

Inputs on the DAC-1600 controller follow the same general wiring requirements as other Delta Controls

products. Recommended cable types should be used as listed below. Refer to the Delta Controls Wiring

Guidelines for more details.

Recommended Cable Type

Where to Use

2 Conductor, 18 AWG, Unshielded

4-20mA, 10KΩ, and 10V input types

2 Conductor, 22 AWG, Shielded

Inputs configured for 5V

Input Configuration

The input must be configured to accept the signal used by

the input device. Place the jumper for each input in the

correct location on the Input Type Selector Block. The

diagram to the right shows the factory default selection of

10 KΩ.

4-20mA For sensors that use a 4 to 20 mA signal.

10K For 10 KΩThermistor temperature

sensors, as well as Dry Contact binary

inputs.

5V For sensors that use a 0 - 5 VDC signal.

10V For sensors that use a 0 -10 VDC signal.
