Specifications
Design
RS422/485 Modbus RTU
Communications Interface
(Optional)
Baud Rate: 4800, 9600,19,200 or 38,400 baud selectable
Data Format: Floating point or integer
Length of Link:
2000 ft (600 m) max. with Belden 9271 Twinax Cable and 120 ohm termination
resistors
4000 ft. (1200 m) max. with Belden 8227 Twinax Cable and 100 ohm termination
resistors
Link Characteristics: Two-wire, multi-drop Modbus RTU protocol, 15 drops maximum or
up to 31 drops for shorter link length.
Ethernet TCP/IP
Communications Interface
(Optional)
Type: 10Base-T
Length of Link: 330 ft. (100 m) maximum
Link Characteristics: Four-wire, single drop, five hops maximum
IP Address: IP Address is 10.0.0.2 as shipped from the Factory
Recommended network configuration: Use Switch rather than Hub in order to maximize
UDC Ethernet performance.
Configuration: Ethernet parameters are configured via the Process Instrument Explorer.
Email: The capability to send an Email is provided. This must be configured via the
Process Instrument Explorer.
Infrared Communications
(Optional)
Type: Serial Infrared (SIR)
Length of Link: 3 ft. (1 m) maximum for IrDA 1.0 compliant devices
Baud Rate: 19,200 or 38,400 baud selectable
Controller Output Algorithms On-Off or Time Proportional
One relay or open collector output. Control action can be set for direct or reverse.
Time Proportional Relay Resolution: 3.3 msec
On-Off Duplex, Three Position Step Control, or Time Proportional Duplex
Two relays or open collector outputs. Control action can be set for direct or reverse.
Time Proportional Relay Resolution: 3.3 msec
Current Proportional
A single 4-20 mA current output signal which can be configured for direct or reverse
action.
Current Proportional Duplex
This can be a single current output can providing both heat and cool signals (4-12 mA
cool, 12-20 mA heat) or a combination of both current outputs with the First Current
Output providing the Heat output (Heat = 50 to 100% of range) and Second Current
Output providing the Cool output (Cool = 0 to 50% of range). Both are 4-20 mA signals
which can be set for direct or reverse action.
Current/Time Duplex
Variation of time proportional duplex for Heat/Cool applications. Time proportional output
(heat or cool) is a relay. Current proportional output (Heat or Cool) is a 4-20 mA signal
that can be fed into a negative or positive grounded load of 0 to 1000 ohms and is
operational over 50% of range or the entire range.
Digital Displays Vacuum fluorescent, alphanumeric
A four-character upper display dedicated to the process variable (4 digits).
Alternate information displayed during configuration mode.
A six-character lower display primarily shows key selected operating parameters (4
digits). Alternate information displayed during configuration mode.
Indicators Alarm Relay Status (ALM 1 or 2)
Control Mode (A or MAN)
Temperature Units (F or C)
