WARNING: Disconnect all power to the unit before
installing Plug-in cards.
Adding Option Cards
The PTC900/PTC/901 series meters can be fitted with up to three optional
plug-in cards. The details for each plug-in card can be reviewed in the
specification section below. Only one card from each function type can be
installed at one time. The function types include Setpoint Alarms (LDP6-CDS),
Communications (LDP6-CDC), and Real-Time Clock Card (LDP6-RTC). The
plug-in cards can be installed initially or at a later date.
COMMUNICATION CARDS (LDP6-CDC)
A variety of communication protocols are available for the PTC900/PTC/901
series. Only one of these cards can be installed at a time. When programming
the unit via the Windows
® based software program, the RS232 or RS485 Cards
must be used.
SERIAL COMMUNICATIONS CARD
Type: RS485 or RS232
Isolation To Sensor & User Input Commons: 500 Vrms for 1 min.
Working Voltage: 50 V. Not Isolated from all other commons.
Data: 7/8 bits
Baud: 300 to 19,200
Parity: No, Odd or Even
Bus Address: Selectable 0 to 99, Max. 32 meters per line (RS485)
Transmit Delay: Selectable for 2 to 50 msec or 50 to 100 msec (RS485)
MODBUS CARD
Type: RS485; RTU and ASCII MODBUS modes
Isolation To Sensor & User Input Commons: 500 Vrms for 1 minute.
Working Voltage: 50 V. Not isolated from all other commons.
Baud Rates: 300 to 38,400.
Data: 7/8 bits
Parity: No, Odd, or Even
Addresses: 1 to 247.
Transmit Delay: Programmable; See Transmit Delay explanation.
PROGRAMMING SOFTWARE
DP6-SOFT is a Windows ® based program that allows configuration of the
PTC900/PTC/901 meters from a PC. This software offers standard drop-down
menu commands, that make it easy to program the meter. The PTC900/PTC/901
program can then be saved in a PC file for future use. A serial plug-in card is
required to program the meter using the software.
SETPOINT CARDS (LDP6-CDS)
The PTC900/PTC/901 series has 4 available setpoint alarm output plug-in
cards. Only one of these cards can be installed at a time. (Logic state of the
outputs can be reversed in the programming.) These plug-in cards include:
LDP6-CDS10 - Dual Relay, FORM-C, Normally open & closed
LDP6-CDS20 - Quad Relay, FORM-A, Normally open only
LDP6-CDS30 - Isolated quad sinking NPN open collector
LDP6-CDS40 - Isolated quad sourcing PNP open collector

QUAD RELAY CARD
Type: Four FORM-A relays
Isolation To Timer & User Input Commons: 2300 Vrms for 1 min.
Working Voltage: 250 Vrms
Contact Rating:
One Relay Energized: 3 amps @ 250 VAC or 30 VDC (resistive load), 1/10
HP @ 120 VAC, inductive load
Total current with all four relays energized not to exceed 4 amps
Life Expectancy: 100K cycles min. at full load rating. External RC snubber
extends relay life for operation with inductive loads
Response Time: 5 msec. nominal with 3 msec. nominal release
Timed Output Accuracy: ±0.01% -10 msec.
QUAD SINKING OPEN COLLECTOR CARD
Type: Four isolated sinking NPN transistors.
Isolation To Timer & User Input Commons: 500 Vrms for 1 min.
Working Voltage: 50 V. Not Isolated from all other commons.
Rating: 100 mA max @ V
SAT
= 0.7 V max. V
MAX
= 30 V
